Poorly designed content management systems (CMSs) can cause more problems for your website than any other single factor.
Your choice of CMS is therefore one of the most important decisions you can make.
The problem with them is that they tend to prioritise the ease of page generation over everything else, something that can play havoc with search engine friendly-ness.
Most e-commerce scripts and simple CMSs now have “SEO friendly” stamped on the box.
Unfortunately most of these are decidedly not SEO friendly. Some of them might offer things like custom title tags and meta tags but this is as far as most systems go.
The real problems arise when the CMS starts creating thousands of useless extra pages on your site. This can cause huge problems and drag your Google rankings down for your real pages.

In cases like this it always pays to have your site reviewed for SEO before it goes live.
