I'm new to SEO and I'm testing on one of our sites here. All of our pages are done using ASP.NET and we use master pages. Does this matter if the page is not plain HTML? Also, does it matter that our content for our pages is in a content control and not just plain HTML... I would like to hear some opinions on this...
The main issue with using ASP.NET and master pages as it relates to SEO is that you are not able to define META tags (content, keywords, etc..) on a page by page basis. Each page will have the same set of META tags - the ones you defined in the masterpage and this is not SEO friendly.
Frankly I don't see any problem from SEO point of view. See as long as the urls of your individual pages are unique to each individual page you're fine. If the content changes but the url address remains the same then its something which search engines won't digest.
Our pages have unique urls but I do see the problem now that our pages will have the same information as the master page... The site I'm testing is a used car dealership... so is it a big deal that I have all of my pages with the same title, meta tags, keywords... etc. The site is really only selling used cars so what would I put on the other pages anyway? Now, say the site is trying to sell custom rims also... This would probably be a problem, correct? Because now the site would be optimized for used cars and not custom rims... What do you guys think?
