Every webmaster is trying to publish quality content on his/ her site to keep visitors satisfied. Quality content is a big technique of White Hat SEO and everyone should try to avoid posting spam articles.
To make your quality content articles even more powerful to the "eyes" of the search engines is very good to use a few tags on your code, which will give more value to what you are writing.
Some of them are:
Title - will give a unique title to your page
Meta Description - will help the search engine find what you wrote about
Meta Keywords - your keywords will be compared with those the user used to search
Heading Elements - giving value and "categorize" what you are writing
<H1>
<H2>
<H3>
Just try to use the above and you will see that you will get more visits to your pages. Let me know if it helped.
