Quick check today shows my osCommerce Templates site is back showing in the Google index. Now what Google is up to is beyond me. This time last week I had been indexed. I was showing for maybe 48 hours max and then dropped again apart from the front page. No reason at all. The site is not a spam site at all, it's a proper shop selling templates along with some affiliate links to eBooks of the same subject. Google seems to have been doing this to a few people however, indexing and showing all of their pages then suddenly dropping them out the SERPs again for a few days.nnNow last week I also happened to read on a forum about the use of filenames and how they work SEO wise and also how they look. On one of my sites I've gone for income and advertising over look which I'm really not a big fan of. I would rather forfit some income or visitors if it means having a better looking site as I believe these will last in the long run. As I already have my main keywords in my url I figured I didn't need to repeat them on a couple of pages so I shorted a couple of filenames (oscommerce-templates.php and oscommerce-ebooks.php) to just use 'osc' instead. This way they're still easy to see in the file structure for myself for updating but they don't look as spammy and it won't make a major difference as far as SEO is concerned.nnThinking that Google had dropped me altogether and would pick up on the 301 permanent redirects that I'd put in place I presumed that it would drop the old pages and replace with the new ones. However it seems that despite Google not showing me in the rankings it's still listing the old sites in the SERPs again even though they've been changed. So what is happening? It seems like Google is indexing a site, showing all of the pages and then hiding them for a short period and then showing them again without updating itself first! For a script (let's face it, googlebot is just a script) it's not highly intelligent at times. Luckily the 301s are still in place and will stay in place for as long as needbe but I'm more interested in what Google is really up to.nnHowever, all that aside, I'm back in the limelight so hopefully a sale or two will happen in the near future and I can make my money back on the site
