I’ve been doing Search Engine Marketing (SEM) since 1995 and founded Didit in 1996. I write a column, Paid Search Strategies, and recently decided to add video on iMediaConnection and on this site. My latest book, Search Engine Advertising, has been well received and includes $200 in Bing (adCenter) credits. Didit runs the D&B online Business Directory, plus I’ve launched a social entrepreneurship venture, We-Care.com, which delivers passive donation revenue to nonprofits.
