wordpress plugins

I was playing around with my comments section as I wanted to style trackbacks differently from “normal” comments, and while playing around, I decided to just bump them down.

xml sitemaps do you need them

There’s a discussion on Webmasterworld as to whether XML sitemaps are a welcoming door for scrapers.

If you have some scripts on your site like, for instance, my domain-info script, you often use GET parameters so people can link to them or bookmark them. This has a lot of benefits, but it creates a problem as well. Search engines will index this output, causing your server to use cycles for something »

I’m currently working on a site for a client who has a site which uses frames, and he asked me why Google always linked to the “wrong” page. He did not build this site himself of course, and hasn’t got much of a clue as to how HTML works, let alone search engines. He asked »
