HTML headings and emphasis tags are the most basic forms to indicate important content.
Tips:
1. use your keywords in the headings and make sure the first level heading (<H1>) includes the most important keywords.
2. never duplicate the title tag content in the heading tags.
3. for more effective SEO, use only one <H1> tag per page |
