[CarolinaFlores]

Hi all friends,
Please tell me most important part of On Page SEO? that helps to increase page rank.

The information available on page is more important. Rather than thinking about keyword density or amount of content, it is best to keep it more informative. In short, the information should meet readers requirements rather than meeting search bots requirements.

Everything about ON Page SEO is important like title tag, interlinking, meta description, image optimization,URL search engine friendliness, sitemap submission etc.

As such there are no list of important SEO techniques but the backlinks you create, it should be of high quality.

I think all part important for on page SEO, but meta tag (title, description.keyword) are very important for rank keyword in google.
