Why do You Need Robots.txt?

It is not necessary for having a roborts.txt in theory, as which is just a document that tells the search engine spider which pages of your site are not allowed to index. But setting roborts.txt correctly can enhance the website’s overall performance.

• The Advantages of Roborts.txt

1.      Provide a Good Start of Crawling

Almost all of the spiders follow the crawling rules the roborts.txt gives. The spiders are required to crawl over a website starting from the site's robots.txt. If your site doesn’t have the roborts.txt, the spiders will be redirected to the 404 page which will confuse the spider and affect the indexing.

2.      Save the Bandwidth

Roborts.txt can stop the unnecessary search engines taking up your valuable bandwidth, such as, email retrievers and image strippers which are meaningless for most of websites.

3.      Protect the Private Pages

It is the original intention of setting roborts.txt to stop the search engine spiders crawling and indexing those private pages which you want to protect, such as, background programs and management programs.

4.      Relieve Crawling Pressure

Sometimes configuring a roborts.txt is even more significant especially for those sites which contain lots of pages. Such a website may bring enormous spider visits, which can affect the normal access to the site. The robort.txt can relieve the pressure.

• The Risk of Roborts.txt

Roborts.txt may also bring a certain degree of risk. It provides the attacker with the site’s structure and the private pages, which reduces the difficulty of attacking. Set access permissions on the private pages to prevent the attacker destroying your site.

Add roborts.txt to your site and make good use of it to get indexed well.
