- Jonathan Trenn, president of Abraham Harrison, a digital marketing company in the DC area, said that if he's starting from scratch with a client he'll use free tools like blog search engine Technorati to locate the bloggers he wants to contact. Specifically, he searches for the tags that the bloggers use with their posts, because this is an indicator of whether the person writes regularly on a particular subject.
"It'll give you a list of blogs to look at," he told me. "You basically start clicking through, and it's essential that you read the blog and get to know it a bit, maybe start categorizing it or put it in a database. But essentially you want to get to know what they are about, see if they're updated frequently."
Technorati and other search tools allow him to then rank the blogs by authority. He said he begins with focusing on the most influential blogs. But he hastened to add that this is only a starting point, and that he can then begin clicking through these blogs' blogrol
