Google, Bing, Qwant need access: Here is how you set-up your robots.txt file correctly.
How to check your robots.txt file: Entry explains how to do it right. In turn, improve your site’s SEO results and traffic.
We address three questions
1. What do robots or crawlers do?
2. What does it mean if a robot cannot crawl the content of your blog or webpage?
3. How to BEST set-up your robots.txt file.
Improve your search positioning and get the latest news on your mobile.
By default, everything on your blog that visitors can see, can be indexed by search engines like Google or Qwant. Indexed content will show up in search results. Most blogs receive about 40 to 70 percent of their visitor traffic from search engines.
You can prevent search engines to index certain pages. This is done by editing your robots.txt file. However, this is usually not in the blogger’s best interest. Below we outline what your robots.txt file must contain to allow Google or DrKPI to crawl it.
What do robots do?
Web robots are sometimes also called web wanderers, crawlers or spiders.
Robots perform various tasks. In the context here we are interested in their work regarding:
1. Site Indexing: they take a copy of a website they find and store this information at the search engine’s servers.
2. Validating the site code – this means comparing the website code to W3C standards and grading the code according to accuracy.
3. Link Checking – this includes tracing incoming and outgoing links.
What should you check for?
While the robots.txt file is a great thing, we can inadvertantly make errors which results in outcomes that we may not want. For instance, recently, I informed a blogger that we could not scan his site. He wrote in reply:
All allowed, only sub-directories are not.”
The above indicates, however, much more is being disallowed then the scanning of sub-directories. For example:
This command prevents search engines (i.e. if they respect the blogger’s wish – DrKPI does, Google…?) to index the blog’s posts. To allow indexing the blog’s content, the command needs to be changed to:
In turn, Google and DrKPI can index the blog posts of this site (read also WordPress – section on robots.txt optimization).
Do I have a choice?
Yes you do. For instance, you have the choice to give a particular crawler permission to index your blog.
In order to allow us to index your blog, while possibly still preventing others from doing so, we need you to add the following two lines to your robots.txt file:
If the above has been added, the DrKPI-bot can then go ahead and crawl your blog, even if you use the command:
Thefore, by entering the above command we can crawl your blog’s content and index it. In return, you get the actionable metrics you want, in order to improve the blog’s performance for your business.
PS: 99.68% of all bloggers allow us to crawl their site. Accordingly, we provide them with the actionable metrics needed to improve their blog.
