Dynamically constructed websites are the hardest type of websites to do seo optimization Below some common issues which we have to face at the time of dynamic SEO optimization are as bellow:
1. Keyword stuffed pages: Long time ago search engines used to love pages with high keyword density. But not now anymore. Dynamic sites generate lot of automated pages. So be aware of pages that contains lot of keywords stuffed. For example, the automatically generated page may contain "ortho dog beds", "foam dog beds", "soft dog beds" etc... in the content. This way, the keyphrase "dog beds" is repeated lot of times.
2. Query strings: If your site is a database driven site, that develops content using the words in the query strings, make sure that you use words that helps for your SEO. If you site is an online shop selling dog products, try to use keywords like "dog beds" or whatever your keyword is, rather than using something like "product=23" in the url.
4. Duplicate page titles: Page titles tells search engines in brief about the page. Duplicate page titles are seen mostly in ecommerce sites. By default, the title will be set and the same title is generated for all the pages.
