Here is another very good question about SEO that I heard today:

How do some websites have such high rankings on google but do not have h1 or h2 tags?

I will probably get a lot of grief about this but,
right now search engine optimization has almost nothing to do with on-page optimization and everything to do with who is linking to you and with what anchor text*.
Only exception I can think of is if you are in a really weak industry in terms of SEO competition, then google will pick up your content without many links pointing back to you.
Periodically Google will change it’s algorithm, or formula for ranking websites, and will weigh different factors more than others.  s
All factors in Google’s algorithm fall into one of three categories:
  • Content – fresh unique content that is highly relevant to the search keyword
  • Activity – how often your site is updated, either by you our by way of new comments posted by readers
  • Links – how many different, relevant sites are pointing back to a particular page
These changes in the way the search engines rank sites happen every time people (spammers) start to figure it out and try to take advantage of temporarily knowing what gets weighed more heavily.
Just now, Google came out with the Panda update mainly to address people distributing the same article to dozens of different websites.  They now discount the links coming from content that is found on multiple websites, also known as the Duplicate Content Penalty.
For the foreseeable future, the search engines will base their rankings most heavily on the links pointing back to your website.  These links act as a vote from people around the world wide web, voting you as most relevant for that given topic.

Back to the question I saw online today.  After asking about H1 and H2 tags, the person went on to ask how to improve search engine ranking on his website.

So here is my quick answer to that.

The top three ways to increase Google ranking (get more links) off the top of my head,

  • blog commenting
  • article/content writing and distribution
  • online press releases, I prefer PR Web

Hope this helps
