- Text format and SEO: Search engines pay special attention to the bookmarked text or special formats. We recommend:
Use the keyword in the title: Title text is highlighted with HTML Heading tags. The H1 and H2 tags are most effective. Currently, the use of CSS allows you the appearance of highlighted text with tags. This means that the Heading tags are used less today, but still very important in the process of SEO.
- Highlight keywords with bold font: Do not stand out in the full text. Just type keywords every two or three times on the site. Strong cards to highlight keywords instead of the more traditional B card in bold tag.
- Title tag: This is one of the most important tags for search engines. Use this in your actual work seo. Keywords must be used in the title tag. The link to your website that is normally displayed in the search results will contain text derived from the title tag.

Typically, 50-80 characters from the keyword title is displayed in the search results and therefore you should limit the size of the header length.
