How should I handle pagination on an e-commerce site?

[EcommerceSite]

I am looking at one of our category pages and it has 25 additional pages for a total of 26 pages. The url for the first page looks good, then the next one ends with ?SearchText=768&SearchType=Category

All additional pages have the same url. My first concern was duplicate content, but after looking no pages after the 1st are even indexed. What is the best way to handle this?

Change the way your ecommerce site paginates so that it shows ?page=x

Then add tags to the headers

My sitemap also I setup to only show page one in it. Should I add them to the site map? Should I use rel="canonical" all back to the first page?

Don't add paginated pages to sitemap.

You should not canonical page to page one... canonical to each of the paginated urls (just strip sessions ids and such)

rel="next" and rel="previous" on the one hand and rel="canonical" on the other constitute independent concepts. Both declarations can be included in the same page. For example, http://www.example.com/article?story=abc&page=2&sessionid=123 may contain:

We don't have any sessionids or anything like that in URLs, so can I just dismiss using rel="canonical" on the additional pages?

[OlegKorneitchouk]

yep

Because they are the same page with different items don't I run the risk of getting flagged with duplicate content? The title, meta description, and the content are all the same besides the list of items.

[OlegKorneitchouk]

That's what the rel="next/prev" does. It tells G that these pages are part of the same list and just the items change.

Thank you for the help.
