Duplicate pages

[vibelingo]

Hi,

I am using a CMS that generates dynamic urls that according to the SeoMoz tool will be indexed as duplicate pages. The pages in questions are forms, blog-posts etc. that are not crucial to achieve ranking for. I do worry though about the consequences of having 20 (non-duplicate)pages with static urls and about 100 pages that are duplicates with dynamic urls. What consequences will this have for the speed that the robots crawl the site and could there be negative effects on ranking for the entire domain?

Can you post a screen capture of the Duplicate Content Report here? That may someone can see what is actually going on, and give you the right suggestions. Thanks.

I don't wish to state the obvious but, duplicate content is bad. You should do everything possible to reduce or eliminate it. If the duplicate content is necessary, then use canonical tags so search engines will clearly understand which page is the primary page you wish indexed.

Your CMS should have an option to add canonical tags to pages automatically.

If you feel the forms do not have any value in SERP, then you can always add the "noindex" tag to those pages.

What consequences will this have for the speed that the robots crawl the site and could there be negative effects on ranking for the entire domain?

There are several factors including domain size, the popularity of your domain, the popularity of the content, and how you are linking to your content. Crawlers often will only check a few pages or percentage of your site on each visit. If you add unnecessary pages, then it can take longer for the other pages to show up in search results.

hi,

this is an example of the type of urls that are "problematic" (if that helps):

hi, thanks. I'll see what I can do with no-index and canonical links. It seems to me that the number of these pages should impede the indexing of the whole domain....
