1) A heading tag that includes a keyword(s) or keyword phrases. A heading tag is bigger and bolder text than normal body text, so a search engine places more importance on it because you emphasize it.
4)A second paragraph could be added that got more specific using other words related to online education.
5)Next you could put smaller heading.
6)Then you'd list the links to your pages, and ideally have a brief decision of each link using keywords and keyword phrases in the text. You also want to have several pages of quality content to link to. Repeat that procedure for all your links that relate to your theme.
7)Next you might include a closing, keyword laden paragraph. More is not necessarily better when it comes to keywords, at least after a certain point. Writing "online education" fifty times across your page would probably result in you being caught for trying to cheat. Ideally, somewhere from 3% - 20% of your page text would be keywords. The percentage changes often and is different at each search engine. The 3-20 rule is a general guideline, and you can go higher if it makes sense and isn't redundant.
