.html or .php?

Hello guys! im planning to make a web development website.. well as of now im starting to create the design the page... I just like to ask some tips.. in terms in search engine optimization... is it advisable to my site to make dynamic of my contents? i mean i want it to make the content dynamic meaning it comes from the database so that i can easily change the text anytime i want.. but i'm just confuse if ever i will do it.. can it will be easily crawl my site into any web search engine?

And anyway is there any reflection if my pages will .php or is it advisable to make it .html? Wink Wink

Search engines have been crawling dynamic sites for many years now, it's really not a technological issue to worry about.

As Salathe said, it doesnt matter. However, the best way for SEO would be to mod_rewrite them to "clean" URL's (eg. site.com/register vs site.com/register.php)

I don't think it matters. I use .php extension on all of my webpages.

Doesn't matter, but as Village said, "clean" URL's seem to look much better (so they look like directories, without extensions).

I've been in the habit of using .html for all page extensions for a while now, for one simple and rare reason: if the dynamic technology ever changes (you move to php to .Net, etc) your page names don't have to change. This allows people who bookmarked your pages to always be able to use those bookmarks and for your pages to keep their ranks without extensive or complicated redirect scripts.

A secondary reason is that using .html hides the technology you're using from potential hackers to some extent. It will keep the kiddies at bay at any rate, anyone who knew what they were doing would still be able to figure it out.

Just my 2 cents. Most people would never run into either of these problems on their personal websites.

All you have to do change MIME types so .php is anything you want it to be.

1) A page's file extension makes no difference whatsoever.

2) Spiders treat static and dynamic pages exactly the same. They crawl the dynamic page's output and nothing else.
