How Many Ranking Factors Does Google Use In Their SEO Algorithm?

Description: It is said that Google may use more than 100 ranking factors in their algorithm. Find out which ones are the most important!

The reason why search engine optimization is so complicated is that there may be 100 or more factors included in Google’s ranking algorithm. This is probably why many people seem to be touting
many different strategies these days. My goal in this article is to explain what I think are the main ranking factors you’re going to need to pay attention to and respect.
Since SEO is split up into two main categories, on-page and off-page SEO, I’ll be splitting them up too. I’m not necessarily ranking them in order of value because nobody really knows for sure which hold the most value. However, it is important for you to try to heed all of them.

On-Page SEO Factors:
1) Keyword in the Title Tag
2) Keyword in the URL
3) Keyword in the H1 Header
4) Keyword in the description
5) Keyword used at least 3% on page and first 100 words of html
6) Page linked to from other pages of the site with keyword in anchor text, links to other pages on the site, and links to external sites
7) Substantive content existent on the page
8) Recent page and content creation
9) Site “crawlability” by Google spiders
Off-Page SEO Factors:
1) Quantity and “quality” of the backlinks to the page
2) Keyword usage in the anchor text of backlinks
3) Link diversity – domains, IPs, countries, and extensions
4) Total quantity and quality of links to the domain
5) Total number of indexed pages on the domain

6) Directory listings in the Yahoo Directory and dmoz.org
7) PageRank
8) Domain age (especially as it applies to brand new domains)
These are the main factors you need to concern yourself with now and as you go along in your SEO training, it will behoove to understand the specifics of each category and which other factors may apply to your site.
What is interesting about the algorithm is that there seems to be an extreme amount of weight put onto certain items and these items can actually outweigh the others completely. For example, there is only so much you can do when it comes to on-page optimization. But you can always continue to build thousands of quality backlinks to a page and that factor may come to outweigh everything else. In fact, I’ve seen a page rank #2 for a keyword with 21 million competing pages and a title of “Page Not Found.” After researching the issue, it was clear that the number of backlinks to the page was allowing the page to rank very highly.
Overall, it is probably best to try to implement all of the above techniques because many of them are easy to do and have proven to be of SEO significance at some point in time.
