Randfish has an excellent summary of the various sessions he attended at SES NY. This is a must read. You can find it at www.socengine.com/seo/guide/ses-nyc/ses-nyc-2005.html. I've pulled out just a few of the snippets of info that I thought were interesting, but there is a lot more there, so be sure to take the time to read it all.
What Matt Cutts from Google had to say:
- Make URLs static or dynamic w/ 2 or fewer URL parameters.
- Just because a link is shown in the link command doesn't mean it carries any weight at all.
- Google still does use PR (PageRank), but that it is only one of over 100 ranking factors in the algorithm.
- Its important for links to come from separate C-blocks of servers if they want to be counted as unique.
What Yahoo reps had to say:
- 301s - leave these in place indefinitely, or at least as long as possible so that link credit can be passed.
- Authoritative links indicate to Yahoo! the need for a deep crawl of the site.
- Webmasters should only use the free addurl service if all else fails, he also says they often find spam through it as un-savvy webmasters submit their spam sites through the addurl service.
