Google’s John Mueller answered a query on Reddit a few generally used robots meta tag and what would occur if it was lacking. Mueller’s reply, whereas it is smart and is documented, should come as a shock to many publishers and SEOs.
Robots Meta Tag
The HTML meta factor communicates metadata. Metadata is machine readable info {that a} crawler like Googlebot can learn.
There are various sorts of meta parts just like the meta description factor however the Robots Meta Component is totally different in that it will probably management the search engine crawlers.
The knowledge communicated by the robots meta tag known as a directive, which implies that robotic crawlers are obligated to obey the directions within the robots meta tag.
There are various instructions to cross alongside by way of the robots meta however the next meta tag is one that’s related to the query John Mueller answered.
The noindex, no comply with meta tag:
The above meta tag tells the search engine crawlers to not index the content material on the webpage and to not comply with any hyperlinks.
One of the frequent meta tags is that this one, which instructions search engines like google to index the content material and comply with all of the hyperlinks:
Whereas the above meta tag is frequent, there’s a important quantity of bewilderment about it. There’s a line of reasoning that as a result of Google helps nofollow then it should suggest that Google helps the comply with directive.
I discovered plenty of authoritative web sites that say that Google makes use of the meta robots index, comply with meta tag.
However that’s not really how Google makes use of these directives, as John Mueller makes clear in his reply.

What’s The Impact Of Leaving Out The Meta Robots Index Tag?
The individual on Reddit requested the next query:
“I’m a bit confused with a website I’m engaged on.
So, that is what the meta snippets on many of the web sites I work on appear to be:
However, on the website at hand, it’s lacking the ‘index’ tag.
My query is: What’s the impact of the location lacking the ‘index’ tag.”
John Mueller answered:
“The “index” robots meta tag has no operate (not less than in Google) – it’s utterly ignored. Additionally “comply with”.
Google has https://builders.google.com/search/docs/crawling-indexing/special-tags & https://builders.google.com/search/docs/crawling-indexing/robots-meta-tag to doc the meta tags which have capabilities. You should use the rest, it’ll be ignored. is an possibility, if you wish to throw folks off.”
Why Google Ignores Robots Index & Observe
The straightforward cause why Google ignores the robots index and comply with meta tag is as a result of indexing and comply with are the defaults.
Indexing and following hyperlinks is what search engine robots do, they don’t need to be instructed to index content material and comply with hyperlinks as a result of that’s their goal.
Google’s documentation on robots tags advises:
“The default values are index, comply with and don’t must be specified.”
The total listing of legitimate directives for Google is right here.
If the robots meta you need to use isn’t’ listed there then Googlebot goes to disregard it.

Is Index, Observe Utterly Ineffective?
It’s true, documented and official that in relation to Googlebot, is a waste of HTML house and is ignored by Googlebot.
Bing treats index, comply with in an identical means however with a slight distinction, as described within the official Bing documentation for meta tags.
That is what Bing’s documentation says concerning the index directive:
“By default we assume “index”, but when wanted you should utilize to explicitly state that we might index the web page.”
And that is what it says concerning the comply with directive:
“By default we assume “comply with”, however you’ll be able to explicitly state “comply with” if that’s the case desired.”
In my 20+ years of working in search engine optimisation creating web sites, optimizing them and rating them, I’ve all the time thought-about it a very good coverage to offer the bots what they count on and check out to not give them something that’s sudden. So if a meta description just isn’t mandatory then my impulse can be to go away it out as a result of the entire level of optimizing is to make it as straightforward as doable for the various search engines to index and perceive the content material, which implies to eliminate something that may work towards that aim.
On this case, it’s extremely doubtless it’s not going to have an impact in some way.
However… There’s one other means that comply with and index journey folks up.
Some publishers use this robots meta tag:
Some websites advise that if the web page isn’t listed, using the “comply with” directive compels the search engine to comply with the hyperlinks.
However that’s not true if there’s a “noindex” directive for the straightforward causes that Google can’t comply with a hyperlink on a web page that it isn’t listed. If it’s not within the index then the hyperlinks on these pages aren’t within the index.
