Drupal 7 Seems to be Great for SEO

I stopped reading after the third paragraph. You seem to associate PageRank with Drupal 7's SEO capabilities - which is totally wrong. PageRank has nothing to do with your site (PageRank is derived from Larry Page and not from web page)! It's all about who and how many people link to your site, that's the only thing that impacts your PageRank. That's really it, not Pathauto, not Page Title, and not much Drupal (internal links count towards your PageRank but in the grand scheme of things play only a minor part.

What you're talking about is referred to a websites SERP Ranking (Search Engine Results Ranking or Positioning). Google's PageRank is just one factor influencing your position in the search results - also it's widely believed that the published PageRank is not the same as the actual one used when calculating, i.e. it lags behind and is static whereas the actual used PageRank is not static but in motion all the time.

So even though your public PageRank made a huge jump at one moment in time - from 0 to 5, it really saw a linear or maybe even an exponential increase over time.

What you experienced is simply the same for all new sites, as you get more popular, you get more links and Google notices you more - at the beginning Google doesn't trust you quite yet and so doesn't put you anywhere near the top of the search results - but this changes after a given time period if there are no indications of you abusing a link farm system or likewise.

Hope this makes things a bit clearer, but mind you, I'm no SEO expert either but have read the occasional SEO article here and there.

Regardless what the previous poster said, I have noticed a jump in page rank for my site, http://takefivemethod.com. It two weeks it went from a 2 to a 4. During this time, it did not receive substantially more traffic nor does it have more external links.

I think it is naive to say that page rank is based solely on external links. Sure, that is a significant portion of the equation, but Google has hinted that good semantic urls hold some weight.

In Google's Webmaster Tools they state "A site's URL structure should be as simple as possible. Consider organizing your content so that URLs are constructed logically and in a manner that is most intelligible to humans."

They go on to say "Consider using punctuation in your URLs. The URL http://www.example.com/green-dress.html is much more useful to us than http://www.example.com/greendress.html"

I suspect that the change DrupalMill and I noticed has more to do with Google tweaking Page Rank than the sudden rapid growth in web site popularity.

I've always done well with with the search engines using Drupal. I've had much more difficulty with getting other sites noticed using some of the other CMS solutions. I do agree though with Dan though that using Drupal likely didn't change your page rank.

I did go from a Page Rank of 5 to 6 after my own upgrade to Drupal 7...but I think that has to do with my increase use of promoting my pages via Twitter than anything else. In the end though, I think "Content is King" and the quality posts are the best SEO of all. Be passionate in your writing and the rest is more likely to follow (visitors, links, popularity, high placement in the search index).

Yet people will still continue to doubt that you *have* to have the nodewords/metatags module in order to do better on SEO. As much as I try to tell them otherwise. :/

now meta tags modul has available... but good writing on drupal site is most important think

Different opinions and suggestions I found in net about seo and page ranking. Somewhere I read that seo friendly theme is also a factor. I have downloaded and installed many modules, but could not notice any increase in page ranking. What is the real factor?
