You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our consolidated financial statements and the notes thereto included elsewhere in this report. The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this report, particularly in the "Risk Factors" section.

Overview

We operate a consumer-driven service for our members to research, hire, rate and review local professionals for critical needs, such as home, health care and automotive services. Our ratings and reviews, which are available only to our members, help our members find the best provider for their local service needs. We had more than 1.7 million paid memberships as of December 31, 2012. We allow local service providers who are highly rated by our members to advertise discounts and other promotions to our members.

We generate revenue from both our members and our service providers. We derive membership revenue from subscription fees and, in certain cases, non-refundable initiation fees for monthly, annual and multi-year memberships. These fees typically are charged in advance. Subscription fees are recognized ratably over the subscription period and initiation fees are recognized ratably over the expected life of the membership. As of December 31, 2012, approximately 91% of our total membership base had purchased annual or multi-year memberships. These subscription fees represent a significant source of working capital and provide a relatively predictable revenue stream.

We derive service provider revenue principally from term-based sales of advertising to local service providers. Our members grade local service providers on an "A" to "F" scale, and we invite local service providers with an average grade of "B" or better and at least two reviews submitted in the last three years to advertise to our members through any or all of our website, email promotions, monthly magazine and call center. As of December 31, 2012 approximately 332,000 local service providers rated by our members were eligible to offer discounts and other promotions to our members based on these criteria. Service provider contracts can be prepaid or invoiced monthly at the option of the service provider and carry an early termination penalty. We recognize service provider revenue ratably over the period in which an advertising campaign is run. We are expanding our service provider sales force to drive increased service provider revenue. Our high service provider renewal rates, both in number of service providers renewing and as a percentage of initial contract value renewed, have provided us with a relatively predictable revenue stream.

In addition to traditional advertising on our website and publications, our e-commerce solutions offer our members the opportunity to purchase services through us from service providers rated on our website. These offerings are available through both email promotions and through postings on our website. When the member purchases the service, the transaction is processed through Angie's List. The member then can work directly with the service provider to schedule the service. These e-commerce offerings provide our members a discount and an easier way to fulfill their service needs.

To establish a new market, we begin by offering free memberships and actively soliciting members' reviews of local service providers. As the number of members and the number of reviews of service providers grow, we begin charging membership fees and offering advertising opportunities to eligible local service providers. Historically, we have begun to convert most markets to paid membership status within 24 months after launch.

Increasing new paid memberships is our key growth strategy. Increased penetration in a market results in more member reviews of local service providers, which increases the value of our service to consumers and

As described further in the "Market Cohort Analysis" below, we believe that our estimated penetration rate and average revenue per market will increase as markets mature, and over the long term, we believe that these increased revenues will more than offset our operating expenses. In addition, our advertising spending, which is our single largest operating expense, is related to the acquisition of new members, rather than the maintenance of existing members. Because our advertising contracts typically are short-term, we can rapidly adjust marketing expense, and thus decrease total operating expenses to reduce cash used in operations or generate cash and profits from operations should we begin to experience adverse trends in marketing cost per paid membership acquisition or wish to optimize for profitability at the expense of rapid growth. We believe that our high membership renewal rates and "word of mouth" referrals from existing members, combined with effective purchasing of lower volumes of advertising and increasing utilization of search engine optimization, or SEO, would enable us to maintain and potentially grow the size of our paid membership base at a lower level of overall advertising spending.

From our inception in 1995 through 2000, we operated primarily as a call center service in mid-sized markets such as Indianapolis, Charlotte, Cleveland and Tampa. In February 2001, we launched our website, www.AngiesList.com, in all 10 of our then-established markets, and almost immediately www.AngiesList.com became our primary service platform. In 2006, we set out to expand our operations to cover all major U.S. metropolitan markets and establish a national footprint, and today Angie's List is operating in 219 paid membership markets across the country.

Recent Developments

Follow-on offering of stock

In May 2012, we completed a secondary public offering of 8,629,797 shares of our common stock, which included 703,235 shares of common stock sold by us and 7,926,562 shares of common stock sold by the selling stockholders (inclusive of 189,374 shares of common stock from the partial exercise of the over-allotment option granted to the underwriters). The price to the public of the shares sold in the offering was $13.00. Proceeds to us were approximately $8.7 million, net of underwriting discounts and commissions. Proceeds to the selling stockholders were approximately $98.2 million, net of underwriting discounts and commissions. We did not receive any proceeds from the sale of shares by the selling stockholders. Total underwriting discounts and commissions were $5.3 million. We incurred fees resulting from the transaction of approximately $0.8 million, of which $0.1 million is included in additional paid-in-capital and $0.7 million is included in general and administrative expenses.

Technology developments

In order to improve our product offerings and grow our technology platforms, we established a technology presence in Palo Alto, California in 2012. With the addition of these new technology engineers in Palo Alto, along with other technology hires, we are working to improve our website functionality and product offerings for our members and service providers and the efficiency of member acquisition in our overall operations.

Selling expense developments

In the fourth quarter of 2012, we commenced the transition to a new compensation plan for our sales force responsible for new advertising originations whereby we have begun to pay commissions as cash is collected

Market Cohort Analysis

To analyze our progress in executing our expansion plan, we compile certain financial and operating data regarding markets we have entered grouped by the years in which the markets transitioned to paid membership status. The table below summarizes this data for 2012 by the following cohorts. The pre-2003 cohort includes our ten most established markets, where we initially built out our business model. The markets in this cohort include several mid-sized urban markets in the midwest as well as Chicago and Boston. The 2003 through 2007 cohort includes the first major subset of markets, including many of our largest potential markets, that we targeted in our national expansion strategy. The markets in these older cohorts have begun to achieve penetration rates that allow us to transition beyond introductory membership and advertising rates. The 2008-2010 and post-2010 cohorts include markets that have most recently converted to paid status and that still have predominantly introductory membership and advertising rates. The markets in these cohorts generally are smaller markets that we entered to fill out our national presence.

(1) Average revenue per market is calculated by dividing the revenue recognized for the markets in a given cohort by the number of markets in the cohort at year end.

(2) Membership revenue per paid membership is calculated as our membership revenue in the cohort divided by the average number of paid memberships in the cohort. We calculate this average per market to facilitate comparisons among cohorts, but it is not intended to represent typical characteristics of actual markets within the cohort.

(3) Service provider revenue per paid membership is calculated as service provider revenue in the cohort divided by the average number of paid memberships in the cohort. We calculate this average per market to facilitate comparisons among cohorts, but it is not intended to represent typical characteristics of actual markets within the cohort.

(4) Average marketing expense per market is calculated first by allocating marketing expense to each cohort based on the percentage of our total target demographic for all markets in such cohort, as determined by third-party data, and then dividing the allocated cohort marketing expense by the number of markets in the cohort at year end. We calculate this average per market to facilitate comparisons among cohorts, but it is not intended to represent typical characteristics of actual markets within the cohort. According to a January 2013 demographic study by Merkle Inc. that we commissioned, there were approximately 31 million households in the United States in our target demographic, which consists of homeowners aged 35 to 64 with an annual household income of at least $75,000. Approximately 27 million of these households were in our markets. The average number of households per market in our demographic target were 425,000, 435,000, 60,000 and 20,000 for the pre-2003, 2003-2007, 2008-2010 and post-2010 cohorts, respectively.

(6) Estimated penetration rate is calculated by dividing the number of paid memberships in a given cohort as of December 31, 2012 by the number of households meeting our target demographic criteria in such cohort.

(7) Annual membership growth rate is the rate of increase in the total number of paid memberships in the cohort between December 31, 2012 and 2011.

Our average revenue per market and total revenue per paid membership generally increase with the maturity and corresponding increased penetration of our markets. However, we may experience declining total revenue per paid membership overall or in some market cohorts. A decline reflects a lag in our ability to leverage increased penetration in a market into increased advertising rates as our average advertising contract term in effect as of December 31, 2012 was more than 12 months and we are only able to increase rates for a given participating service provider upon contract renewal. In addition, the decline reflects rapid membership growth in less penetrated markets where the average membership and service provider revenue per paid member is lower than in more penetrated markets. We also have adopted a dynamic pricing model in 68 of our mature markets to offer members the opportunity to purchase only those segments of Angie's List that are most relevant to them. These segments continue to be offered in all other markets as a single bundle. We anticipate unbundling our offerings in more of our markets as market penetration increases and the number and categories of local service providers reviewed by members in such markets grow. We believe this pricing model will enable us to offer a better value proposition to our members and preserve cross-selling opportunities as members' needs evolve. Although we expect that this strategy may result in lower average membership fees per paid membership overall, we believe the new members generated by this pricing model should ultimately produce increased service provider revenue per paid membership.

As a market matures, our penetration rate typically increases. Historically, while the absolute number of paid members may grow faster in large markets, our small and medium markets have often achieved greater penetration over a shorter time period than our larger markets. We believe that a principal reason for our lower penetration rates in large markets is the manner in which we market Angie's List to our target demographic in such markets. We have chosen to spend 100% of our marketing dollars on national advertising. We believe that this advertising strategy provides us the most efficient manner of acquiring new paid memberships. However, advertising nationally means we deliver the same volume of advertising regardless of the size of the market. Since each market differs in terms of the number of advertising outlets available, the impact of our spending on national advertising varies across markets. In our experience, smaller markets typically have fewer advertising outlets than larger markets. We believe the same volume of advertising in a smaller market is more effective in building brand awareness and generating new memberships than in larger markets. We expect to continue to see lower relative penetration rates in our larger markets for these reasons.

At least annually, we receive updated demographic data in the total addressable market and in the markets in which we offer paid memberships. In periods where there is a significant increase in the demographic base in a particular cohort, our penetration rate may remain steady or fall. From 2011 to 2012, the total addressable demographic in the United States increased from approximately 29 million to 31 million households, and our total addressable demographic in the markets in which we offer paid memberships increased from approximately 25 million to 27 million households.

Key Operating Metrics

In addition to the line items in our financial statements, we regularly review a number of other operating metrics related to our membership and service provider bases to evaluate our business, determine the allocation of resources and make decisions regarding business strategies. We believe information on these metrics is useful

                                                            Years Ended December 31,

Total paid memberships. Total paid memberships reflects the number of paid memberships at the end of each period presented. Total paid memberships also includes a de minimis number of complimentary memberships in our paid markets for all periods presented. We generally expect that there will be one membership per household and, as such, each membership may actually represent multiple individual consumers.

Gross paid memberships added. Gross paid memberships added reflects the total number of new paid memberships added in a reporting period. Gross paid memberships added increased substantially in each period presented, which we believe has been driven by our increasing investment in national advertising and, to a lesser extent, by "word of mouth" referrals from our existing members.

Marketing cost per paid membership acquisition. We calculate marketing cost per paid membership acquisition in a reporting period as marketing expense divided by gross paid memberships added in that period. Because we advertise in national media, some of our marketing expense also increases the number of unpaid memberships. On a comparative basis, marketing cost per paid membership acquisition can reflect our success in generating "word of mouth" referrals and experimentation and adjustments to our marketing expense to focus on more effective advertising outlets for membership acquisition. We typically have higher marketing expense in the second and third quarters of the year in order to attract consumers during the periods when we have found they are most actively seeking Angie's List services. Our marketing expense is normally reduced in the fourth quarter, reflecting reduced consumer activity in the service sector and higher advertising rates generally due to holiday promotional activity.

Membership renewal rates. First-year membership renewal rate reflects the percentage of paid memberships expiring in the reporting period after the first year of membership that are renewed. Average membership renewal rate reflects the percentage of all paid memberships expiring in the reporting period that are renewed. Renewal rates do not include monthly memberships, which comprised approximately 9% of our total membership base as of December 31, 2012. Given the correlation between increased penetration and higher total revenue per paid membership, we view first-year membership renewal rate and average membership renewal rate as key indicators of expected operating results in future periods.

Participating service providers. We include in participating service providers the total number of service providers under contract for advertising at the end of the period.

Total service provider contract value. We calculate service provider contract value as the total contract value of active service provider contracts at the end of the period. Contract value is the total payment obligation of a service provider to us, including amounts already recognized in revenue, over the stated term of the contract.

In addition, we also track contract value backlog as a key metric. Contract value backlog consists of the portion of service provider contract value at the stated date which has not yet been recognized as revenue. At December 31, 2012 and 2011, our contract value backlog was $82.1 million and $46.2 million, respectively.

Revenue

Membership revenue. Our members sign up for monthly, annual or multi-year subscriptions to our service. Membership revenue includes subscription fees and, in certain cases, non-refundable initiation fees charged to new members. We charge the full price of membership at the commencement of the subscription period and at each renewal date (whether monthly, annual or multi-year), unless the member chooses not to renew the membership before the renewal date. Our members prepay their membership fees at the commencement of the subscription period. We record prepaid membership fees as deferred revenue and recognize the fees as revenue over the subscription period. We charge a non-refundable initiation fee in connection with monthly memberships and the lowest cost annual memberships in less penetrated markets. We recognize revenue from non-refundable initiation fees over the expected life of the membership, which we currently estimate to be 12 months for monthly memberships and 68 months for annual and multi-year memberships, based on our historical experience.

Service provider revenue. Local service providers generally pay for advertisements in advance on a monthly or annual basis. Our average advertising contract term in effect as of December 31, 2012 was more than twelve months. The vast majority of our service provider contracts cover a period of twelve months. This term allows us to have a predictable revenue stream while providing us an opportunity to adjust advertising rates at the renewal period as our membership penetration of a given market increases.

We recognize revenue from the sale of website and call center advertising ratably over the time period in which the advertisements run. We recognize revenue from the sale of advertising placement in Angie's List Magazine in the month the advertisement is published and distributed. As our penetration of a given market increases, we are typically able to charge higher rates for advertising because service providers are able to reach a larger base of potential customers. However, because we only increase advertising rates at the time of contract renewal, increases in service provider revenue in a given market may trail increases in market penetration.

Our e-commerce offerings primarily consist of Big Deal and Storefront, which allow our members to purchase services or products from our service providers through us. We receive a portion of the offer price at the time of the purchase, recognizing the revenue net of the total transaction. Revenue is recognized in the period the offer is sold to members and is included in service provider revenue. While we are not the merchant of record with respect to our members for these transactions, we do offer members refunds in certain circumstances. Revenue from e-commerce transactions is recorded net of a reserve for estimated refunds.

Operating expenses

Operations and support. Operations and support expense consists primarily of costs associated with publishing Angie's List Magazine, operating our call center and providing support to our members and service providers, including wages and other employee benefits, credit card processing fees for member enrollment and other transactions on our website, report transcription and data entry, and amortization of the cost of acquired data. Operations and support expense does not include the cost of maintaining our website, which is included in technology expense. With the growth of our membership base, we expanded our call center staff to maintain high levels of customer service and encourage high renewal rates. We also use third-party marketing research firms to enable our members to submit reviews by telephone to enrich the content available to our members and expand the number of service providers eligible to advertise with us. We expect our operations and support expense to increase in absolute dollars in the future as we continue to grow our membership and scale our operations.

Selling. Selling expense consists primarily of commissions, wages and other employee benefits for personnel focused on selling and renewing advertising to eligible service providers. We pay substantially higher commissions to our service provider sales force for contracts with first-time participating service providers than we pay for renewals. Our e-commerce sales personnel earn commissions based on the net revenue received from the sale of Big Deal and Storefront offerings. Selling expense also includes the cost of service provider marketing
