What are meta tags?

At its most basic, meta tags are snippets of text that tell a search engine what a web page is about — meta tags don’t appear in the body of a page, but in the code itself.

Meta tags are undoubtedly useful from an SEO perspective, since they allow search engines to more easily categorize your web page’s content. Common examples of meta tags include canonical tags, meta content types, robots meta tags, or title tags.

Let’s dive into some of these, now.

1. Canonical tags

If you have a single page with multiple URLs, or different pages with similar content (such as a page with a mobile and desktop version), search engines see these pages as duplicate versions of the same page.

For instance, as a human, you know “” and “” point to the same page — if you search for either, you’ll land on Google’s homepage.

But Google sees “www” and “https://” as duplicate versions of the same page. If you don’t specify which page you want to be the “real” or “original” source, Google will choose which source it dubs original, and crawl the other pages less often.

This could mean that Google consistently crawls your mobile version of your homepage, and rarely checks your desktop version.

For this reason, it’s often important to include a canonical tag, which simply tells Google, “Hey, if you find this same content elsewhere — please disregard. This is the source I want you to see, and this is the version I want to appear in the SERP’s.”

This is especially important for pages like your homepage. To insert a canonical tag, simply put this code in your HTML:


2. Meta content type

The meta content type enables you to specify the media type (i.e. “text/html”) and character set for each web page — you’ll want to include this on all of your web pages. This information ensures your pages are displayed correctly on all browsers.

Here’s an example of the code you’d use for meta content type:


3. Robots meta tags

If you don’t specify a robot meta tag, search engines will obey the default index,follow command. However, there could be reasons you want to change the robot meta tag to influence the behavior of search engine crawling and indexing.

Here are a few common robot meta tags:

  • noindex — Prevents the page from being indexed.
  • nofollow — Prevents Googlebot from following links from this page.
  • nosnippet — Prevents a text snippet or video preview from being shown in the search results. For video, a static image could be shown instead.
  • noarchive — Prevents Google from showing the Cached link for a page.
  • unavailable_after:[date] — Allows you to specify the exact time and date you want to stop crawling and indexing of this page.

There are various reasons you might use a robots meta tag. You might input the “nofollow” command, for instance, if your web page has a comments section. Since you can’t control which links are posted by readers in the comments section (which could be off-topic to your page’s content), it might be smart to tell search engines not to follow those links.

Alternatively, “noindex” is a popular tag for a few reasons — for instance, let’s say you’re planning to launch a website redesign, but want to test the redesign on a development server that lives in a subdomain on your website. You’ll want to use the “noindex” tag to ensure Google won’t release the site in search before it’s ready.

You might also use “noindex” if you have a gated content offer you don’t want users to be able to find on search engines — since you want them to fill out a form to access it.

Lastly, you might use “noindex” if your website creates unique web pages whenever someone does a site search. Search engines might think those pages are part of your website, which will hurt your SEO. It’s best if you incorporate “noindex” to ensure site search results aren’t displayed on the SERP’s.

To incorporate a robots meta directive, input this code into your HTML:


4. Title tags

Title tags help readers initially understand what your content is about, and is also a major factor in helping search engines understand your content’s subject matter. Additionally, a title tag can ensure consistency, since the title tag will show up on your web page, on the web browser, and in social networks.

If you don’t include a


It’s important to note, alt text is technically not a tag — it’s an attribute. However, you’ve likely heard the term “alt tag”, which is why you might think alt text is part of the meta tag family (I know I did …).

Regardless of its categorization, alt text is incredibly important for your overall SEO strategy, particularly since Google places more value on visual search nowadays. When a search engine crawls your page, it’s going to look for the alt text of an image as an identifier for what your web page is about — so it’s critical you correctly title your alt text.

Here’s a code example for alt text to incorporate in your HTML: Meta tag picture.

Meta tags vs. meta descriptions

Meta descriptions are one example of a meta tag — simply put, a meta description is a 160 character-limit snippet of text a user can read on a search engine. A meta description tells the user what they’ll find if they click on your content — which, if done correctly, can greatly increase click-through rates.

The tag doesn’t influence ranking directly, but it’s nonetheless an important element of SEO — a good meta description can compel readers to click on your article, and if the meta description accurately describes your content, the user is more likely to stay on the page. Click-through rates do influence search engine ranking, so meta descriptions are important for SEO.

Here’s an example of the code you’d use to manually input a meta description into your web page’s HTML:




While meta descriptions are a subcategory of meta tags, there is a fundamental difference between the two — purpose. Meta tags are used to help search engines figure out the content of your site, but meta descriptions are used to help a user sort your content.

For instance, consider what happens when I search “what are meta tags”:

The meta descriptions for the following two articles are more than likely the primary reason I’ll choose one article over the other.
