Hi,

I was hoping someone could give me some info on how sites like ebay work.

When you upload an item, is the items features put into a data base then this data is dynamicaly generated to a html page each time someone looks at the item or is a new page created then stored in the database?

Sorry if that isn't explained well :)

Also, if these items are dynamically generated from a database, how can google index them?

Any info would be greatly appreciated.

Thanks :)

Usually the pages are dynamically created using a template and contents from the database. So no, the full html page is not stored in the database.

When a request is made for a particular URL, the code on the web server will programatically extract these elements and what is sent to the browser or the search engine bot will be html code and so that is what will be rendered/indexed.

Thanks,

That makes ense now. I think i was getting confused because i thought google wouldn't be able to search the database and my site would become part of the "dark web". But i see now that bots dont access my database directly.

Cheers :)
