Well it is in Googles eyes if you dont have good relevant content that is!
Yep it had to happen and the engines in their wisdom are now heavily weighting their algorithmn on the content side. So what can you do if you have a pure Ecommerce site with only products? Write or have written for you good quality content that enhances the products you sell. Simple really!
You can moan about this all you like but the fact is The search engines prefer content over anything at the moment. Lots of links with good content will win for you all day long.
