Why Google doesn’t like frames in your sites

2 April 2007 by Joost de Valk » - 9 Comments

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 »

Convert underscores to dashes with Apache mod_rewrite

25 March 2007 by Joost de Valk » - 1 Comment

Update: (Aug 4 2007) the stuff below is no longer necessary, all major search engines now treat underscores and dashes exactly the same, as word separators!

17 March 2007 by Joost de Valk » - 8 Comments

This query gives a result I hadn’t seen before (image), the same page was indexed with both a single trailing forward slash, which is of course normal, and with a double trailing forward slash… This is of course a duplicate content issue, especially when people link to the double slash one by accident.

15 December 2006 by Joost de Valk » - 3 Comments

Man I was cocky when I entered the scholarship contest. I though I’d beat everybody easily. The amounts of traffic that other articles were getting weren’t very impressive, I thought, and I was sure to be able to get much more traffic.

Why PageRank says nothing about rankings

16 October 2006 by Joost de Valk » - 15 Comments

Sometimes you’ll get clients who say “my PageRank is x, yet I don’t get any visitors from Google”?. Understandable, I think. If you were graded 6 out of 10, by the biggest search engine out there, it’s only fair to expect some traffic, or isn’t it?
