How are SEOs done for dynamic websites? Whether each page is separately built static?

I had a food takeaway website where the us开发者_运维百科ers can search the restaurants by giving their area name. I want my website's LONDON search page to be listed when user searches in Google TAKEAWAYS IN LONDON.

I think google doesn't crawl websites with query string. How can we achieve that?

Remember that Google just looks at the page you create, not how you create it.

Now this basically translates your question to "how do we make our dynamic pages visible to Google"? There are a number of tricks. Basically you build links from your homepage to specific other pages. You could have a "Top 5 searches" box, with links to "http://www.example.com/london/takeaways" etc. On the result pages, you can have links to similar queries, e.g. "http://www.example.com/london/finedining".

Basically, Google will see and follow those links, and remember the results per URL. The basic SEO rules till apply - good content, clear structure, etc. Don't bother Google or users with query strings. Use URL rewriting if a query string easier for you internally.

Maybe you're supposed to have a sitemap, which could have a discoverable link to a page of yours whose URL is http://www.food.com/london and whose title and heading is 'TAKEAWAYS IN LONDON' (and whose contents you can retrieve dynamically).
