SEO Gyan by Matt

• Matt claims that Google treats URLs with a query string the same as static URLs. Caveat: as long as there are no more than two or three parameters in the URL, that is! Put another way, you won’t take a hit in your Google rankings if you have a question mark in your URL; just don’t have more than two or three equals signs in the URL.
• Matt stated that the number of slashes in your URL (i.e. the number of directories deep your page is) isn’t a factor in your Google rankings. He went on to say that although it doesn’t matter for Google, it is rumored to matter for Yahoo and MSN (Live Search). Matt addressed this because I specifically asked the question from the audience.
• According to Matt, the file extension in your URL won’t affect your rankings. So it’s inconsequential whether you use .php, .html, .htm, .asp, .aspx, .jsp etc. The one extension you should avoid for your Web documents? .exe.
• Matt stated it was myth that Google uses its status as a domain registrar to access domain registration data to use it as a ranking signal. According to Matt, being a registrar doesn’t grant one special access to other registrars’ customer data. Note that Matt didn’t state whether Google is or isn’t using WHOIS data as a signal. I believe they are.
• When asked about how to get one’s blog into Google News, Matt shared one of Google’s requirements for inclusion: the blog must have multiple authors. So those of you wanting your blog showing up in Google News results, I hope it’s a group blog!
