Will I lose my Google Page Rank?

I have had the idea of revamping one of my sites so that I can more easily run dynamic content on it. I want to change the site from a html site to a php site.

Now all the pages would be exactly the same urls but instead of being .htm extension they would be .php extension. Will this cause my google page rank to disapear?

Can someone please tell me how to do this the correct way.

Many thanks

 

You will not gain pagerank on the new pages since the extention will be different. I would keep the old pages up and use 301 Redirects to let the spiders know of the new pages. Check this out for more information on 301's:

Don't sweat it too much.

 

Cheers for the reply, so will the 301's need to be there indefinately or can I remove them after a period of time?

 

you cant change the page's file name to retain the PR.

 

Use htaccess to make your html pages parse like they are php pages. That way you don't need to change the names.

 

Mad4, how is this done? Sounds interesting.

 

Stick this in your .htaccess file:

 

So you're just setting a MIME TYPE? So you can now include PHP into HTML files? Am I understanding this correctly?

 

use 301 permanent redirect from old URLs to new ones. Hope it works.

 

If you change .html to php then any how search engine point of view it is consider as new page .So solution is redirect the hrml url's to .php

Your page rank will 0 for some days and in next page rank update you will get some page rank

But NO ONE CAN'T GUARANTEE HOW MUCH PAGE RANK YOU WILL GET ? May be same, less or more.....But google given above i mentioned as solution to issues like this

 

I agree. I would go and set up 301 redirects if I were in your shoes.

 

depends. search engines love content. if you are replacing text with writing google can't read (in a flash or image design) then yes it will lose page rank.
