How to do pagination in ajax call?

What's better: to load the page and then make ajax call to get inventory or load the page with the inventory?

• Using an AJAX call is faster and better for user experience; loading inventory with the page is better for SEO, but may reduce the speed. Any ideas or preferences?

• Answer:

  My personal choice: load the page with the inventory then enable ajax for loading more items and browsing the pages. I usually build the entire web application without using ajax and then enrich the user experience with ajax and javascript. This way my pages are  usable by the widest possible choice of browsers and tools (not only search engines, think about screen readers or indexing tools and users without javascript). For the user load time problem i would preferably try caching at least the first page or parts of it.
