.htm pages Vs .aspx pages

[Manish Verma]

Plzz tell me some facts with reason that what happens when we change a .htm page into .aspx page, with reference of search engine optimization??

Manish, that's whole different pages. You have to use a permanent redirect from the old to the new to avoid getting caught with duplicate content, and it will take a while for the new pages to start producing like the old ones did.

It's best to retain the same file extensions if you can, but if you can't then you have to do what you have to do.

There is no difference at all between having one or the other extension but what DOES matter is if you already have a site using one extension and then change it. To search engines it will look as all new pages. Also, all links pointing to the old files are lost.

You can save some of it by using a 301 permanent redirect from the old files to the new ones - 1-to-1

Another solution would be to set up your server so it parse html as .NET but if you go from html to aspx there are most likely a lot of other things changing as well (such as session IDs' parameters etc) and then it won't help.

I thought .aspx and .net servers had the ability to use the ISAPI rewrite.

If so you can just use that rewrite to tell your server to accept .htm as .aspx. You won't have to do redirects or lose your page scores.

If your server admins don't know about the rewrite or it's not installed. Then they can find this version handy www.isapirewrite.com

Yes, you can do that, but I all you want to do is have the webserver parse HTML as as aspx then you can just map it for the website. That is much easier to do, faster, cheaper and it do not creates the level of new problems that dealing with rewriting does.

I'll be the first to admit I'm a windows newb :) Give me apache mods any day :D

I would not label myself Windows expert either but I do have a few servers running - and they still work :)
