Building my site... again

I started my HTML career back in the days when the newest MS Word-version came with a "save as html"-function. I saved as HTML, read the code, and learned by myself bit by bit. By the time I got my hands on HTML for dummies, I realized I was no dummy after all :) But now, asking this, I feel kinda dumb... Its got to do with PHP, search engines, meta-tags and headers. I am building my site like this: - I have an index.php-file, that takes two variables, page and subpage. A link on my site may look like this: <a href="index.php?page=cars&subpage=ferrari"> (for instance) Now, my index.php-file will do this: (basically) <html> <body> if($page){ include($page . ".inc"); } </body> </html> and my cars.inc will do this: if($subpage){ include($subpage . ".inc"); } Now. I would of course like for my site to be listed in the search engines, and I wouldn't mind getting search hits on both cars and ferrari. But. Will the web spiders and web crawlers ever follow a link like index.php?page=cars&subpage=ferrari and will they ever index what they find there, and, and, and, and... Well... does anyone understand what I'm asking here? WOuld this be a good way to build my site to ensure getting hits from search engines, or should I do this some other way? Anyone know? - Torkil
