Crash course: Everything you need to know about HTML tags with regard to SEO

If you want to improve your SEO, this will certainly sound familiar to you: With all the measures, you can’t see the wood for the trees.

Sometimes it is also important to go back to basics and strengthen your foundation: the HTML code of your website.

From title and meta tags to image alt texts and the correct use of links – we explain the basics of SEO tags.

You will also learn how these fundamental HTML elements can not only make your website more visible, but also improve its ranking in search results.

What are HTML SEO tags?

We are talking about certain tags that are inserted into the HTML code, i.e. the source code of your website. The most important tags include the canonical tag, the title tag and the image alt tag.

These HTML tags make it easier for search engines like Google to understand web pages and help to evaluate relevance and optimize the user experience.

For this reason, the well-known tag, for example, has no significance for SEO, as it is only important for formatting texts, but not for classifying content.

7 important HTML tags that you should know as an SEO

The most important HTML tags that have a direct influence on SEO:

HTML Title Tag

The title tag is one of the most important HTML tags for SEO. It tells both Google search users and the search engine itself what content is on the page.

The title tag is displayed in the search results as click text and should therefore be concise and relevant.

Meta tags

The meta description tag provides a summary of the content of a page. This is displayed under the title tag in the search results.

A well-written meta description can increase the click-through rate.

The meta robots tag gives the search engines instructions that a certain page should not be crawled (nofollow) or indexed (noindex).

Header tags

Header tags structure the content of a website. The H1 tag should contain the main keyword of the page, while H2, H3 etc. represent subheadings.

This structure helps the search engine to understand the content and index it correctly.

Canonical Tag

If you have pages with similar or identical content, the canonical tag helps to avoid duplicate content by referring to the main version of a page.

This is important to prevent problems with duplicate content, which can have a negative impact on rankings as your pages may be competing with each other.

Image Alt Tags

Alt tags offer a text alternative to images and are particularly important for screen readers that pass on the alt text to blind or visually impaired users.

They also help search engines to understand the image content. Your website will also appear in image searches with keyword-optimized images.

Tips for optimizing alt tags

• Descriptive: Use descriptive and concise texts. A good alt text explains what can be seen in the image.
• Keyword integration: Integrate meaningfully relevant keywords without spamming.
• Uniqueness: Avoid generic descriptions like “Image1”. Each alt text should be unique and specific.

Example of a good Alt Tag: “Photo of a laptop on a desk with an open notebook and a cup of coffee”

Nofollow link tags

Nofollow tags signal to Google that they should not follow a link. This prevents them from passing on linkjuice, but can still bring traffic and increase user trust.

They are a useful tool for optimizing the link structure of your website and controlling unwanted links.

You can also use nofollow tags for paid links, sponsored content or unreliable sources to minimize the risk of penalties.

Links and anchor text tags

Internal links help to clarify the structure of a page, while external links refer to other high-quality content.

Both types are important for SEO as they improve the user experience and help search engines understand the context and relevance of content.

A well-chosen anchor text is a positive ranking factor, as it informs users and Google about the content of the linked page.

Best practices for the use of links and anchor texts:

• Relevance: The anchor text should reflect the content of the target page and give users a clear indication of what the linked page is about.
• Variety: Don’t always use the same anchor text. Natural and creative linking looks more organic and can be better for SEO.
• Natural integration: Place links in such a way that they do not disrupt the flow of reading and fit organically into the text.

The role of the title tag for search engine optimization

The title tag is one of the strongest ranking factors. Search engines regard this HTML tag as an important signal for the content of a page.

A well-optimized title can significantly improve the relevance and click-through rate (CTR) of your website.

Best practices for creating effective title tags

• Keyword integration: Integrate the main keyword at the beginning if possible, as search engines give more weight to the first words of a title tag.
• Length: Keep the HTML title under 60 characters so that it is displayed in full in the search results.
• Uniqueness: Each title tag should be unique and specific to the page in question. Duplicate title tags can lead to confusion for search engines and affect the ranking.
• Attractiveness: The HTML title tag should be appealing and encourage the user to click. Even if clickbaiting is tempting, do not use misleading information to avoid a high bounce rate.

Do HTML meta tags influence the ranking?

Influence of the meta description on SEO

Although the meta description is not a direct ranking factor, it plays an important role in increasing the click-through rate of your website.

A higher CTR can in turn indirectly improve your rankings, as Google sees positive user signals as an indicator of relevant content.

So be sure to write an appealing description under 160 characters that summarizes the content of the page and encourages the user to click.

Relevance of the meta robot tag for SEO

In addition to the meta description tag, there is also the meta robot tag. This is crucial for controlling indexing and crawling by Google.

With instructions such as “noindex” or “nofollow” you can prevent certain pages from appearing in the search results, from being crawled or from passing on linkjuice.

For example, “noindex” can be used in the HTML code so that pages that are irrelevant for SEO, such as login pages or thank you pages, are not indexed.

SEO tags improve the visibility of your website

HTML tags are more than just code – they are an essential element of search engine optimization. By understanding and using these tags correctly, you can significantly improve the visibility and position of your website in Google search results.

Meta tags, title tags and alt tags can increase the click-through rate and contribute to the relevance of your website. Links and anchor text tags help to better understand the context of content.

Header tags structure your page and help Google to understand the content and index it correctly. You can use nofollow tags so that pages without SEO relevance are not crawled.

As you can see, each of these tags has a specific role for your website and contributes to the overall success of your SEO strategy.
