Headings are a part of the SEO architecture. This means the interaction of structure, content and functionality of a website on the positioning in search engine searches. It is therefore also called website architecture or web design architecture. They fall under search engine optimization.
In SEO architecture, among other things, special attention is paid to the technical structure of a website, because this is recorded and evaluated by the crawlers of the search engines. Among other things, the so-called title tag also pays into the evaluation for the ranking of the SERPS in the search engines.
The title tag is the heading of the website and is the first thing that the searcher sees on the Internet. This is assigned in the source code of the web page and should be a maximum of 70 characters long.
Headings (Hx) should be defined in the Cascading Style Sheet (CSS) and should follow some rules.
For example, the main heading (H1) has the highest priority. Thus, the sub-heading (H2) has the second highest priority and H3, as a sub-sub-heading, has the third highest priority, and so on. The designations are to be continued maximally up to H6. The font size and design are chosen according to this prioritization. In addition, all headings (especially the title tag) should include the relevant keywords for the page.
Equally important is the frequency of use of the respective headings (Hx) on the website. The H1 should only appear once on the website. This sets important signals for Google about the relevant content. This is followed by the H2 and H3, each of which may be used more frequently.
The paragraphs between the headings should be sensibly structured with links and bolding. But don’t overdo it with optimization, because this will be penalized by Google rather than rewarded. In addition, the website should still be the most appealing to the customer.
