Top 10 Most Important HTML Meta tags for SEO - Tebiko Digital Agency

In the vast world of SEO, understanding and correctly applying HTML meta tags can mean the difference between success and anonymity in search engines. These tags, although invisible to a page's visitors, are essential to search engines, providing crucial data about the site's content. From improving relevance to avoiding duplicate content, each tag has a specific role that helps optimize the page for better indexing and ranking. Here we will explore the ten most important meta tags that every SEO professional should know and use effectively.

1. Title Tags

They are crucial as they appear in search results as the main heading. They must be precise and descriptive.

  • Use the main keyword in the title, for this post our keyword is html meta tags.
  • Keep titles between 50 and 60 characters.
  • Add your brand name at the end of the title even though it may not appear.

Meta Descriptions

They help describe the page content in search results, increasing the likelihood that users will click.

  • Include the main keyword in the title
  • Use between 150-160 characters for your description.
  • If it is for a product/service use action words "Buy now" "Quote here".

3. Meta Tag Robots

They control how search engines index pages and follow links, essential for managing the visibility of certain pages.

  • Close unnecessary or unfinished pages with sparse content that have little value and are not intended to appear in the SERPs.
  • Eliminate pages that unreasonably waste tracking budget.
  • Make sure you don't mistakenly restrict the indexing of important pages.

4. Canonical Tag rel="canonical"

Important to avoid duplicate content problems by signaling to search engines which version of a page is the main one.

  • Pages with similar content on the same topic.
  • Duplicate pages available under multiple URLs.
  • Versions of the same page with session IDs or other URL parameters that do not affect the content.
  • Use canonical tags carefully for almost duplicate pages: if the two pages connected by a canonical tag differ too much in content, the search engine will simply ignore the tag.

5. Meta Tags for Social Networks

Like Facebook's Open Graph and Twitter Cards, they optimize how links are viewed on these platforms.

  • og:title - Here, you place the title you want to be displayed when your page is linked to. og:url - The URL of your page.
  • og:description - The description of your page. Remember that Facebook will only display about 300 characters of the description.
  • og:image - Here, you can put the URL of an image that you want to be displayed when your page is linked to.
<meta property="og:title" content="The Rock" />
<meta property="og:url" content="" />
<meta property="og:image" content="" />


6. Schema Markup

It improves how search engines understand the page content and can improve the appearance in rich results. Have structured schema markup:

  • It's a big boost to your user experience.
  • It has enormous SEO value.
  • Improves understanding of the content.
  • Helps to appear in SERP features.
  • Increases the chances of obtaining enriched fragments.

Best practices

  • Study the schemas available on
  • Create a map of your most important pages and decide the relevant concepts for each one.
  • Implement the markup carefully (using the Structured Data Markup Wizard if necessary).
  • Thoroughly test the marking to ensure that it is not misleading or incorrectly added.


7. Heading Tags (H1-H6)

These are another of the most commonly used HTML meta tags. They organize the content and help both users and search engines to understand the structure of the articles.

  • Keep your headings relevant to the text they describe.
  • Although they are not a ranking factor, that does not mean that search engines do not take them into account.
  • Always make sure your headings reflect the feeling of the text they are placed over. Avoid headings such as "Chapter 1... Chapter 2... Chapter 3...".
  • Do not abuse tags or keywords in them. Maintain readability for users

9. Image Alt Attributes

Essential for image optimization, they allow to describe the content of the images to search engines.

  • Do your best to optimize the most prominent images (product images, infographics or educational images) that are likely to be searched in Google Images.
  • Add alternative text on pages where there is not much content other than images.
  • Keep the alt text clear and descriptive, use your keywords in a reasonable way and make sure they fit naturally into the overall content of the page.

10. Hreflang Tag

Crucial for multilingual sites, it tells search engines which language and region a specific page is intended for.

External or outbound links are those links on your site that point to other sites. They are used to refer to proven sources, direct people to other useful resources or mention a relevant site for some reason. These links are very important for SEO: they can make your content look like a complete and well-crafted piece backed by reliable sources or like a link dump with not-so-valuable content.

Google is known to dislike manipulative linking tactics, the tracking of which can result in a penalty. Furthermore, in the age of semantic search, Google may treat the sources you refer to as context to better understand the content of your page. For these reasons, it pays to pay attention to where and how you link.

By default, all hyperlinks are followed, and when you place a link on your site, you basically give a "vote of confidence" to the linked page. When you add a nofollow attribute to a link, you instruct search engine bots not to follow the link (and not to pass any link equity).

<a rel=“nofollow” href=“”>Apple</a>
