Top 20 Contributing Factors For Google SEO

Keyword Use Factors

The following components relate to the use of search query terms in determining the rank of a particular page.

1. Keyword Use in Title Tag - Placing the targeted search term or phrase in the title tag of the web page's HTML header.

2. Keyword Use in Body Text - Using the targeted search term in the visible, HTML text of the page.

3. Relationship of Body Text Content to Keywords - Topical relevance of text on the page compared to targeted keywords.

4. Keyword Use in H1 Tag - Creating an H1 tag with the targeted search term/phrase.

5. Keyword Use in Domain Name & Page URL - Including the targeted term/phrase in the registered domain name, i.e. keyword.com plus target terms in the
    webpage URL, i.e.seomoz.org/keyword-phrase.


Page Attributes

The following elements comprise how Google interprets specific data about a webpage independent of keywords.

6. Link Popularity within the Site's Internal Link Structure - Refers to the number and importance of internal links pointing to the target page.

7. Quality/Relevance of Links to External Sites/Pages - Do links on the page point to high quality, topically-related pages?

8. Age of Document - Older pages may be perceived as more authoritative while newer pages may be more temporarily relevant.

9. Amount of Indexable Text Content - Refers to the literal quantity of visible HTML text on a page.

10. Quality of the Document Content (as measured algorithmically) - Assuming search engines can use text, visual or other analysis methods to determine the
