Search Engine optimization URL change from static to Dynamic

Many have asked the question what happens if the URL is changed from html to PHP or ASP or vice versa. Well in Search engine optimization URLs shouldnt be changed often. Search engines recognize a page based on the URLs so once they are indexed its not recommended to play with them much. Google assigns pagerank to individual URLs based on backlinks to that page from other pages from the site or from external sites. So if a Url is changed it will affect Search engine optimization. The pagerank of that page is lost and Google also have to drop that page from the index. Also till the page is dropped you need to wait or Google will index the new page with the new URL which will result in lots of confusion happening. Duplicate pages will be created and at times the version you want to have will drop off. So its important to decide which version of urls you want to use whether php or asp or html or htm or what ever decide before you start designing the site. There is no difference between a PHP url and a html URL so if you think in future there will be dynamic contents in the page better name it PHP or ASp or any dynamic extension of the code you want to use.

Ok if you have unavoidable reasons where you want to change the page extensions then make sure the old pages are 301 redirected to the new pages that are created that way you won't loose the value of the old page. 301 redirect for all coding is available online you can use it.

Best recommendation don't change URLs unless you have unavoidable reasons. That is the best for Search engine optimization purposes.
