ReachLocal has moved beyond its core search engine marketing technology to offer a display advertising product aimed at local businesses.

The new product, dubbed ReachDisplay, allows advertisers to target consumers geographically, demographically and contextually. The service pushes ads across major national sites but only displays them for local visitors who match advertiser-specified criteria.

One interesting feature we haven’t seen elsewhere is the ability to serve specific ads to users who have previously interacted with a Web site. ReachDisplay also shares data with the company’s PPC product – ReachSearch – to track if a customer has previously searched Google, Yahoo, AOL and other engines for a particular business.

All of ReachLocal products aim to walk potential local businesses, who may be new to online advertising, through the entire process, from ad placement and creative bidding through performance tracking of their campaigns. The company offers unique phone numbers to measure conversions.

ReachLocal has 30 offices four countries – the U.S., U.K. Canada and Australia. The company was founded in 2004 and has raised $68 million.
