An interesting Matt Cutts interview from December
Stephen Spencer has a great interview with Matt Cutts of Google, from last month’s Pubcon. Almost all of it is SEO-related. But it also contains a few tidbits that may be interesting even if one doesn’t care about SEO, such as:
- Google now indexes up to 1/2 a megabyte per page, up from the old 101K limit.
- Google needs to do a fair amount of image recognition, but they’re going fairly plain-vanilla. For Flash they use an Adobe-supplied SDK. For detecting hidden text (e.g., white-on-white) they use what Matt characterizes as pretty simple heuristics.
- As I noted recently, Google seems to have a lot of heuristics for identifying particular types of pages. In this interview, the example was that a page that would otherwise seem spammy because it consisted only of links would be fine if it were serving as a true site map or archive.
SEO highlights included:
- Thousands of links on a page: Bad. Hundreds of links: Might be OK.
- 3-4 hyphenated keywords in a URL: Fine. 15 keywords: You’ll get less credit for each keyword than if there were fewer. (I imagine WordPress blogs are a big reason the penalty isn’t more draconian.)
