Hi,
i have a big problem! Im very badly positioned on google!
That's probably why dynamic pages are ard to be read by robots!
So i wanted to rewrite php pages into html pages
How to do it?
thanks

You can take a look at THIS news article and also THIS forum thread, both of theme here on xoops.org, though is your site has plenty of content the pr will go up in some time or wait until new core will be released as it is rumored to have sort of simplified url thing

Check out the website MyWebResource.
This website has a lot of interesting articles with a useful hints and tips.

EDIT: I just had a look at the source of your website and saw that the meta description of your website is 'Homepage'. I think a better description might help also.
Using english meta keywords along the italian keywords can help also.
Adding the keyword 'guitar' is pretty useful if your site is about guitars....

Try XBS MetatTags to automate/manage your keywords. See http://xoobs.net

As your page is mostly images, I suggest making sure you supply good descriptive 'alt tags for all your images (a few are blanks).

Your reason for poor positioning in Google probably has nothing to do with xoops, or queries in the URLs or meta tag content. Google has no problems crawling XOOPS URLs and takes most of its index data from actual page content, rather than meta tags.

Other search engines DO rely on meta tags AND have problems crawling URLs with query strings, so that may be worth considering in terms of using XBS and simplified URLs hack

Google places XOOPS sites very high in page rankings and search results. I can attest to this on my own sites and many others here will agree with this. Sure there are improvements we could do to improve ratings, but first and foremost, you need lots of relevant content and I mean 100s or 1000s of pages all having your keywords/phrases high up in the pages.

Then as many incoming links from high PR sites as possible which are releavant to your own content.

Daily input also helps a lot, as site with changing content is recognised as 'newsworthy' Google is more likely to crawl frequently with regular changing content.

It's all been written here before, so do some digging as suggested above.
