Crawlers, or also known as the robots or spiders, are databases that is utilized by search engines to spot a website, scrutinize it, and then decide its significance, therefore the results will produce the ranking for each keywords. According to research, there are two spiders that are very active compared to the others- the Googlebot and the Yahoo Crawler.
Here are some techniques on how to manage them:
It is very important that SEO’s know what they’re dealing with. They should know how the crawlers work, how they investigate a website and their standards in ranking, so that they could provide the needed information.
So here it is! Now we know what the spiders would look for every time they check a website- your robots.txt file. Robots.txt file is basically a plain message that is put in the directory of a server root. It is a file which provides data whether or not the search engines would index the site as a whole or only a portion of it. There are a lot of tools that is available for this, but the Google Webmaster Tools is highly recommended in generating this file since it is easily understandable. If it is already checked, do not forget to remove it so to avoid duplicity.
Search engine spam exists, and it always gives us a headache. We want to minimize all the existing variables that would trigger this, and in return improving the efficacy of the search engines, thus delivering the best service to the web users. There is a characteristic enveloped in the link that directs engines not to use the link to induce an effect to the link’s target search engine location. This HTML is what they called, a rel=”nofollow”.
When you allow the general public to comment on your site, the links of those messages could pass your standing to some sites you may not be comfortable guaranteeing. Spam messages are very common and to make sure you’re not doing junk sites, not following is the best thing to do.
“nofollow” to forums and message columns
This suggestion may also be used with referrer listings, comment columns or message boards. You can do it by yourself by turning on comment moderation or using an application called Captcha.
“nofollow” for single content, etc.
It can be used by giving a warning to other sites without staining your site reputation. For instance, you’re making a blog on a certain topic such as, dealing with crawlers and you want to mention a site that commented that your post is a spam, and you want to caution others by placing the link in the subject, and then use the “nofolllow”, so that it will not be traced back from your link.
“nofollow” via robots meta tag
This scheme is written as <meta name “robots” content=”nofollow”>. This is situated within the <head> tag of a specific page’s HTML.
Spiders will scrutinize everything in your site; you just have to let them look into the right directions. This will manage the traffic in your site and will give you the possibility of increasing your rank.
