Item 7.01 Regulation FD Disclosure.

On May 10, 2011, Russell C. Horowitz, Marchex’s Chairman and Chief Executive Officer, established a new sales plan in accordance with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (“Rule 10b5-1”) with sales commencing thereunder following the termination of all sales under Mr. Horowitz’s previously established sales plan and John Keister, Marchex’s Executive Vice Chairman of the Board, established a new sales plan in accordance with Rule 10b5-1 with all previously established sales plans by Mr. Keister having expired or been terminated.

Under the new Rule 10b5-1 plans, (i) Mr. Horowitz will sell up to a maximum of 405,000 shares over a period of up to nine (9) months commencing September 1, 2011 which, if the maximum is sold, represents approximately 4.9% of Mr. Horowitz’s current direct and indirect holdings of Marchex common stock, approximately 1.5% of the currently outstanding Class B common stock of Marchex and approximately 1.1% of the currently outstanding total common stock of Marchex, and (ii) Mr. Keister will sell up to a maximum of 540,000 shares over a period of up to six (6) months commencing June 10, 2011 which, if the maximum is sold, represents approximately 21.9% of Mr. Keister’s current direct and indirect holdings of Marchex common stock, approximately 2.0% of the currently outstanding Class B common stock of Marchex and approximately 1.5% of the currently outstanding total common stock of Marchex.

These plans provide (i) for pre-determined sales of a portion of their Marchex common stock as part of their individual long-term asset diversification and liquidity strategies, subject to certain contingencies, and (ii) for sales of specified share amounts at specific market prices, subject to specified limitations, and require that such sales be disclosed publicly through appropriate filings with the Securities and Exchange Commission.

Marchex permits its directors, officers and certain employees to enter into stock trading plans with respect to Marchex common stock which are intended to qualify for the safe harbor under Rule 10b5-1, subject to Marchex’s applicable guidelines and policies on insider trading. The Rule 10b5-1 plans identified above were adopted in accordance with Marchex’s Code of Conduct for all officers, directors and employees. Rule 10b5-1 permits the implementation of written, prearranged stock trading plans by insiders when the insiders are not in possession of material non-public information. Such plans allow insiders to diversify their holdings and to minimize the market impact of stock sales by spreading them out over time.

The information in this Item 7.01 is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section. Such information shall not be incorporated by reference into any registration statement or other document pursuant to the Securities Act of 1933 or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
