How to get search engines crawl data
I have a web application that uses user controls and pulls data directly
from database and shows it to users in the internet. So there is not html
that has the data, if I need to get Google or other search engines to crawl
these pages, what are my options?

If the data is displayed as default then the search engine will read it as
html, if your users have to click on a button for example to get the data
then of cause it will not be indexed

Thanks for the reply. Data will be displaying via page_load, it is not in
html, is there any workaround?

Any default data which is displayed during Page_Load will be picked up by a
crawler...

Pretty much everything displayed on a web page is HTML in one form or
another - exceptions obviously include things like Flash etc, but this
doesn't apply in your case...

Thanks for the reply. I am talking about the data coming from database, on
the fly, I am still not clear how a search engine would crawl it while the
data is simply on the client’s browser basically. Can you give me more detail
please?

You have to understand how search engine crawlers work. They load a page,
index it. In the process they look for links ("A" tag) in the page. Then they
proceed to load each linked page and they repeat the process. It does not
matter *Where* your content is coming from. Hope that helps.

Thanks Peter. I think it is getting more clear but just to make sure I do not
miss anything; The data grid has the data shown to a user base on criteria in
page_load in code behind, let’s say search engine somehow crawled this page
successfully at that specific time while page is loaded just because somebody
has access that page. When the user close the page, input criteria is lost,
data is not available anymore on the screen. Now are we saying that since
search engine has crawled this page it will be able to include that page into
other people’s search result? If yes, the search engine should be keeping
those data somewhere, where would that be?

The crawler will load the page as if it is a client, it will simply follow a
URL. what ever loads no mater where it comes from will be indexed. It does
no matter what users are using the page at the time. the crawler is the
user, how it loads when the crawler follows the links is what will be
indexed
