How important is it to have different meta keywords on php pages that have dynamic content? Should I even worry about this? does is make a difference? Should I try and make them dynamic as well to display whets in the database as well, and is it will it be worth my effort?

Depends on the structure of the website. Is it CMS, or online builder? If so, yes each page should really have Title, Description and it won't hurt to throw in keywords depending on how much coding the bots have to go through to get to the guts of your site.

Also use a site map and be detailed with it.

Database all depends on what's calling it and how it's indexed or not.

Since the dynamic pages are calling up a text page for example it could very well miss it or even index that text file then the user misses the whole site.

Now, I'm all over the place with this reply but there are many different factors to consider and I'm kinda fishing for more

keywords don't have a lot of use anymore you can still use them but remember you should only have one to 4 phrases keep them short and to the point AND the keywords MUST be located in the text on that page or they are pretty much useless...

what you do really need to ensure is that all your title and descriptions are different for each page of the website...

I agree with Orion. It is more important to have unique titles & meta descriptions. You can leave the meta keywords tag out without any problems. You might lose a tiny bit of traffic from msn/yahoo, but it is probably an acceptable loss considering how much time it would take to write meta keywords for each page.

Meta tags are no longer important, except the title & desc meta tags. In the absence of both, SEs will give their own versions.

If you're using the php to dynamically create links for products you could have -

nameofyoursite.com/?product1.php

or you could have

nameofyoursite.com/little-blue-racing-car-toy

Which looks easier to read and more relevant. Sometimes when doing searches I will click on something because I'm sure it's the item I want to buy. I don't want to waste time guessing. Not every search engine cares, but you can generate more traffic than not by using detailed long tail urls.

It's hard to keep a unique meta (keywords) if you have a lot of content. I used a tool that parsed out keywords from my content and added them. So now all my articles have unique keywords and description.

Dynamic is better but for title and description has to be care full to keep unique.. Duplication will raise error on webmaster tool and this effecting ranking tooo

Include all your meta tags in Database along with products so that when ever your page will appear relevant tags will also shown on pages.

Any source or you can provide on this fact?

If you need that SE give weight on each pages then its required that each page have separate meta Tag. But its not required that you place all meta tag on each page.

Only work on Title and Description because most of the SE only crawl these tag. So if you have number of pages then your developer make a script in database and your pages automatically extract title and description from content.

Its a ethical and simple way which used by all dynamic sites.

Meta tags help the search engine understand that the pages are unique. Therefore having the unique meta tag on each page of your website is a good idea. And it make your pages don't look the same too.
