No, you just can't tweak your site's ranking in the most popular search engines by acquiring
high-tech electronic equipment, you know. This process takes a lot of time, a lot of mind power, and a lot of codes! Yes, with the proper coding of your site, web crawlers of the most widely used search engines could properly index your site for its contents. But, let the final words of the last sentence I've thrown be something you remember whenever you think about the optimization of your site's ranking on the most widely used search engines.
Yes, web crawlers of widely used search engines thrive on the contents of your site regarding proper indexing or cataloguing. Thus, including a
login account on the home page of your website would be a very big no-no. You see, these site crawlers rely on information that is either in the textual contents of your site or the textual contents of your codes. With login accounts, the web crawlers of the most widely used search engines of the world wide web are prevented to access the main contents of your site! Why? Of course they don't know anything about getting into the heart of your site by either registering for an account, or hacking right in!
