Among the most important aspects of seo process are the session ids. In their shopping carts most of the websites put the session IDs in the URL. This is required so that the shopping carts can track down the visitors. It would therefore be better for you to store information in cookies so that anyone who tries to link with one of your products could end up linking to URL that has a session ID attached to it.

Cookies however cannot sort out the issues relating to search engines since the search engines do not accept them. You can therefore adopt alternative procedures like detecting the search engines with access to the HTTP_USER_AGENT. If this does not work you can see whether the cookies are turned on. Write a cookie and try reading from it immediately. If the cookies are on you will know at once. This works for all search engines and helps you to effectively put in place your search engine optimization system.

The other vital aspect of search engine marketing is the page ranking. The more the number of links on a page the less is the ranking of each link. For example you may have 4 links on a particular page. 3 out of them redirect you to page where you wish to go and one to a page that you do not wish to visit. This results in 25% wastage, quite costly for your seo project.

For effective seo building you have to address these issues adequately.
