Special meta tags officially supported by Google

Special meta tags officially supported by Google are announced in the Search Console Help . It’s in English, but it’s also explained in the video, so be sure to watch it.

Here is a table summarizing the supported special meta tags and their roles.

[ List of tags supported by Google ]


Meta tags that you want to write carefully


A description tag is a tag that briefly describes what the content of the page is . The description of the page set in the description is displayed as follows.

Descriptions are explained in detail in the next section, so please refer to that.


The “robots” / “googlebot” meta tags have the ability to control the behavior of crawling and indexing search engines .

The “robots” meta tag works for all search engines . The “googlebot” meta tag , on the other hand, is only valid for Google ‘s search engine .

Now, let’s check what description settings are in the “content=”…, …”” of the two tags .

Tag description Description meaning
nofollow Tell Google not to follow page links
noindex Tell Google not to register ( index ) the page
none Instruct to do noindex, nofolloe
no image index Tell it not to show up as the referring page for the image in search results
no snippet Tell Search not to show your meta description

Use the above tags according to the content and intent of the page .

Also, if you check the HTML of the page , you may find that the “robots” meta tag is missing. Even if it is not described, the crawler will crawl properly, so there is no problem.

Some meta tags have no effect

Meta tags other than those listed above are not officially supported by Google . For example, meta keywords (meta Keywords), which were once considered to be meta tags that are effective for SEO . As you can see from the table above, Google does not support meta keywords, so currently it is said that there is no impact on SEO .

Precautions when setting meta tags

Meta tags are not displayed on the web page , so some people may forget to check them. A company that outsources the production of a website needs to check how the meta tags of the delivered website look like.

Meta descriptions and title tags , in particular, are tags that can affect search results and click-through rates. Set it carefully.

Set the meta description to match the content

Among the meta tags , “ meta description (meta name=”description” content=” page description” /) ” is especially important . Meta descriptions are meant to give searchers and search engines an overview of your page . Writing a meta description does not directly affect SEO , but it is important to increase the probability of users clicking.

Many users decide whether to view content based on the “ title ” and the “ page description (meta description) ” below the title . If an appropriate meta description is set, the click-through rate can be increased, and it is easy to lead to an increase in the number of PVs .

It is NG to forcefully use keywords in the title

Google has announced that title tags affect search rankings . Crawlers use the title tag as one of the indicators for crawling the site .

However, it is absolutely NG to force search keywords into the title part . By inserting an appropriate title that understands the content of the page , the crawler can understand the content of the page correctly and the possibility of being ranked high increases. Also, an attractive title is important to increase the click-through rate of users.

title tag point

The point of setting the title tag is to make it easy for users and crawlers to understand, attractive and tempting to click.

Specifically, here are some tips:

  • A descriptive title of the page
  • Enter appropriate keywords
  • Don’t include keywords that aren’t relevant to your page

Let’s set the optimal title that suits the page while keeping the points down .

Set up appropriate meta tags to tell Google about your site

This time, I introduced the meta tags officially supported by Google . In particular, the setting of title tags and meta descriptions that make it easy to understand the content of the page is an important part that affects search rankings and click-through rates.

With reference to the article, set up appropriate meta tags the page , and aim for a website that is highly displayed and clicked.
