Google Explains The Index, Follow Meta Tag

Google Explains The Index, Follow Meta Tag


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 sensible and is documented, should still come as a shock to many publishers and SEOs.

Robots Meta Tag

The HTML meta ingredient communicates metadata. Metadata is machine readable info {that a} crawler like Googlebot can learn.

There are lots of sorts of meta parts just like the meta description ingredient however the Robots Meta Aspect is totally different in that it might probably management the search engine crawlers.

The knowledge communicated by the robots meta tag is named a directive, which implies that robotic crawlers are obligated to obey the directions within the robots meta tag.

There are lots of instructions to go alongside by 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:

<meta title="robots" content material="noindex, nofollow">

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 to index the content material and comply with all of the hyperlinks:

<meta title="robots" content material="index, comply with">

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 a variety 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 particular person on Reddit asked the following question:

“I’m a bit confused with an internet site I’m engaged on.

So, that is what the meta snippets on a lot of the web sites I work on seem like:

<meta title=’robots’ content material=’index, comply with ….

However, on the web site 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 (at the least in Google) – it’s utterly ignored. Additionally “comply with”.

Google has & to doc the meta tags which have features. You should use the rest, it’ll be ignored. <meta title=”robots” content material=”topranking bestcheese”> is an choice, if you wish to throw folks off.”

Why Google Ignores Robots Index & Observe

The easy 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 should be instructed to index content material and comply with hyperlinks as a result of that’s their objective.

Google’s documentation on robots tags advises:

“The default values are index, comply with and don’t have to be specified.”

The total listing of legitimate directives for Google is 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 the case of Googlebot, <meta title=”robots” content material=”index, comply with”> is a waste of HTML house and is ignored by Googlebot.

Bing treats index, comply with in an identical method 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 use <meta title=”robots” content material=”index”> to explicitly state that we could index the web page.”

And that is what it says concerning the comply with directive:

“By default we assume “comply with”, however you may explicitly state “comply with” if that’s the case desired.”

In my 20+ years of working in search engine marketing creating web sites, optimizing them and rating them, I’ve all the time thought-about it a very good coverage to present the bots what they count on and take a look at to not give them something that’s surprising. So if a meta description will not be crucial then my impulse could 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 major 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 method that comply with and index journey folks up.

Some publishers use this robots meta tag:

<meta title="robots" content material="noindex, comply with">

Some websites advise that if the web page isn’t listed, the usage of 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 not comply with a hyperlink on a web page that it’s not listed. If it’s not within the index then the hyperlinks on these pages will not be within the index.
