Does This Affect Search Engine Placement

Hi, I've written a site in PHP which talks to a MySQL database to retrieve posted messages.

In order to cycle through the posts I have a newer and older button that basically call the same page again but with an argument for the start and end post to retrieve from the DB.

i.e index.php?start=5&end=10

Will a spider or bot follow through these pages? The fact that these pages are always changing (i.e the page with 5->10 is always sliding with new posts) is this a bad move for getting ranked. would it be better to use standard generated pages that are always the same?

phew...hope this makes sense!

you use dynamic page. search engines prefer static pages. It does impact your SERPs

Google seems to index dynamic pages like these. But you've better have some static link navigation links to these pages from the main page of your site.

You could try to give a direct link to one of such pages from a page already indexed by Google and wait for the result. Most probably it would be indexed.

Though some older search engines probably would not index the pages where parameters are passed by GET. Could you try to pass the same parameters by the POST method ?

Maybe I am wrong about it, but Google seems not to like completely static pages that NEVER change. It seems to be useful once a month to add a sentence or cut one form the page. It was noticed by one of my friends that sometimes after this the page raises by several positions in Google index. I checked it - it seems to work. Though maybe it is just a coincidence.

thanks for that info...

I think I'll write a listing page that that links to every post individually using static url's and see how this affects things. I will do this along with the current dynamic pages
