The other day I had a pageís rank change from the first page to the second (no big deal it happens), the next itís not listed in google apart from doing a site: search. Today itís back on the second page.
This got me looking into reasons why and I found a tool on this site to check onsite optimization. This is showing a few 500 errors on links, these change if rerunning the tool but always 1 or 2. However when browsing my site I donít seem to get any???? what might cause this? and would it give an explanation to what has happened to my page?
Is there any other tools I can test something like this with? So I can show my hosting company as they have asked if I can replicate this.
