Search engine optimization, in its the majority of basic sense, relies upon something above all others: Online search engine spiders crawling and indexing your site.
But nearly every website is going to have pages that you do not wish to include in this expedition.
In a best-case situation, these are not doing anything to drive traffic to your site actively, and in a worst-case, they could be diverting traffic from more important pages.
Thankfully, Google enables web designers to inform online search engine bots what pages and content to crawl and what to ignore. There are a number of ways to do this, the most typical being utilizing a robots.txt file or the meta robotics tag.
We have an exceptional and comprehensive description of the ins and outs of robots.txt, which you should certainly read.
But in top-level terms, it’s a plain text file that lives in your site’s root and follows the Robots Exemption Procedure (REPRESENTATIVE).

Some meta robotics tags you might use consist of index, which informs online search engine to include the page to their index; noindex, which informs it not to add a page to the index or include it in search results; follow, which instructs an online search engine to follow the links on a page; nofollow, which informs it not to follow links, and an entire host of others.
Both robots.txt and meta robots tags are useful tools to keep in your toolbox, however there’s likewise another way to instruct online search engine bots to noindex or nofollow: the X-Robots-Tag.
What Is The X-Robots-Tag?
The X-Robots-Tag is another method for you to control how your webpages are crawled and indexed by spiders. As part of the HTTP header reaction to a URL, it controls indexing for an entire page, along with the particular aspects on that page.
And whereas using meta robotics tags is relatively uncomplicated, the X-Robots-Tag is a bit more complex.
However this, obviously, raises the concern:
When Should You Utilize The X-Robots-Tag?
According to Google, “Any instruction that can be used in a robotics meta tag can likewise be defined as an X-Robots-Tag.”
While you can set robots.txt-related regulations in the headers of an HTTP reaction with both the meta robots tag and X-Robots Tag, there are specific situations where you would wish to use the X-Robots-Tag– the two most typical being when:
- You wish to manage how your non-HTML files are being crawled and indexed.

Maybe you do not want a certain page to be cached and desire it to be not available after a particular date. You can utilize a combination of “noarchive” and “unavailable_after” tags to instruct online search engine bots to follow these directions.
Essentially, the power of the X-Robots-Tag is that it is much more versatile than the meta robots tag.
The benefit of using an X-Robots-Tag with HTTP reactions is that it enables you to utilize routine expressions to execute crawl regulations on non-HTML, as well as use specifications on a bigger, worldwide level.
To assist you comprehend the distinction in between these regulations, it’s useful to classify them by type. That is, are they crawler regulations or indexer regulations?
Here’s a handy cheat sheet to discuss:
|Crawler Directives||Indexer Directives|
|Robots.txt– utilizes the user agent, permit, disallow, and sitemap directives to specify where on-site online search engine bots are enabled to crawl and not permitted to crawl.||Meta Robotics tag– enables you to define and avoid online search engine from showing specific pages on a website in search results.
Nofollow– enables you to specify links that need to not hand down authority or PageRank.

Please keep in mind that understanding how these instructions work and the impact they have on one another is important.
For instance, what happens if both the X-Robots-Tag and a meta robotics tag lie when crawler bots discover a URL?
If that URL is obstructed from robots.txt, then certain indexing and serving directives can not be found and will not be followed.
If instructions are to be followed, then the URLs containing those can not be prohibited from crawling.
