Hello everyone! First off, this is my first post here, and I'm very excited to have found this very informative site. I couldn't find the answer to the question, so I figured I'd post up. I'll explain the scenario, and then ask the question. Scenario: The site is, for example, a movie review site. It has 3 php pages, named: categories.php, movielist.php and moviereview.php. Each of these pages is populated through a PHP variable being passed in the URL. For example: 1. categories.php has a list of all available categories in the db. The list is made up of links to movielist.php. 2. movielist.php shows a list of all movies in a certain category, that category being decided by a PHP variable passed through the URL. for example www.domain.com/movielist.php?category=action This would show all the movies in the category "action" 3. moviereview.php shows the actual review of the movie. The particular review is decided by a PHP variable passed through the URL. For example www.domain.com/moviereview.php?reviewid=23 This would show the movie review of movie 23. My question is, if I have 100 movie reviews in 10 different categories, I would have 111 different php pages. However, there are only three different PHP pages, each of which are populated by passed variables. How do the Google crawlers view this? Do they conclude that my site has 3 pages with virtually no keywords? Or do they see the 111 pages with tons of keywords? I need to know this information for the planning process of my website. Thanks in advance, I know you guys will have the info I need.
