LinkFreeze

  LinkFreeze, version 2.1, is a powerful tool that provides you with a fast and easy way to make search engines index every link on your web-site and rank them high. With the help of LinkFreeze it is really easy to modify dynamic links on your site so that they will look like static file links, favored by search engine robots. Dynamic content is what most search engines don't really like. They usually will not go deep indexing links with parameters, give such files much less pagerank or even refuse to crawl dynamic pages at all. If you are running a database driven site, for example an online store, and use query strings in your links, search engines will often index them not in a proper way.
LinkFreeze can rewrite these URLs to make them look like static links. Static HTML links, unlike dynamic ones, are easily spidered by search engine robots. The great advantage of LinkFreeze is that it allows you not to leave the code of your pages as it is, since the program works as an ISAPI and the changes to all links on the page are applied the very moment this page is requested on the server. So, to users, search engine spiders or any other clients dynamic links will be presented in the form of static ones. The moment such a link is clicked by any user LinkFreeze will intercept his request on the server and rewrite URL back to the dynamic form. That means that your applications will still be thinking they are working with old dynamic links.
LinkFreeze is also safe for your current applications and backward links because all old dynamic links will remain working. Also it should be noted that the changes applied by LinkFreeze to your links will hide the technology your site is running on since there will be no .asp file extension in the link anymore. LinkFreeze is really flexible and you can configure the substituting characters and file extensions separately and apply different settings can be applied for different parts of your site.
