Cheers for pointing me in the direction of the adwords keyword tool too. I’ve used it in the past but it looks like it’s had a major overhaul since I last used it.

I’m also already registered with Google Webmaster Central too, but thanks for the hint anyway. There’s no red flags in there so I do genuine think it’s just the content/category re-jig that’s thrown my rankings down the pile for now.

Your rankings certainly haven’t fallen because your PR has increased. But you shouldn’t take too much notice of the pagerank in the Google toolbar, it’s very approximate and only updated now and again. Your real pagerank, which Google uses to help rank the site, is a much more complicated logrithmic score that is updated frequently, but never made public. An upward trend in the toolbar figure is a positive indicator, but it’s far from definitive.

Content is much more important, and it is more likely the content changes that have made the difference. There’s a lot you could change for the better and you might want to have an SEO specialist give your site a once-over. There’s lots Google may have taken a dislike to, including the sheer size of the home page.

That will tell you search numbers on the Google network for the previous month.

I also recommend you register with Google Webmaster Central and check to see if you have any penalties before proceeding with further optimisation.

Sorry to see you’re booked up, we could have done with you this month, but keep up the good work. Hope all goes well with the baby.
