What is the best way to employ log-in to benefit in SEO?

[vtmoz]

Hi all,

All SaaS companies have this log-in page as their top visited page in their websites and some times it helps and also hurts them. I've gone through some big SaaS companies websites and they handle the log-in page differently like on sub domain, on website page, some will directly link to their instance login without a page, etc...I wonder what is the best practice to host the log-in to make sure the more visits to log-in page don't hurt us but give us some boost.

Thanks

Beware of the Login pages – add them to Robots Exclusion

A lot of sites today have the ability for users to sign in to show them some sort of personalized content, whether its a forum, a news reader, or some e-commerce application. To simplify their users life they usually want to give them the ability to log on from any page of the Site they are currently looking at. Similarly, in an effort to keep a simple navigation for users Web Sites usually generate dynamic links to have a way to go back to the page where they were before visiting the login page, something like: Sign in.

If your site has a login page you should definitely consider adding it to the Robots Exclusion list since that is a good example of the things you do not want a search engine crawler to spend their time on. Remember you have a limited amount of time and you really want them to focus on what is important in your site.

Out of curiosity I searched for login.php and login.aspx and found over 14 million login pages… that is a lot of useless content in a search engine.

Another big reason is because having this kind of URL's that vary depending on each page means there will be hundreds of variations that crawlers will need to follow, like /login?returnUrl=page1.htm, /login?returnUrl=page2.htm, etc, so it basically means you just increased the work for the crawler by two-fold. And even worst, in some cases if you are not careful you can easily cause an infinite loop for them when you add the same "login-link" in the actual login page since you get /login?returnUrl=login as the link and then when you click that you get /login?returnUrl=login?returnUrl=login... and so on with an ever changing URL for each page on your site. Note that this is not hypothetical this is actually a real example from a few famous Web sites (which I will not disclose). Of course crawlers will not infinitely crawl your Web site and they are not that silly and will stop after looking at the same resource /login for a few hundred times, but this means you are just reducing the time of them looking at what really matters to your users.
