Positive On-Page SEO Google Ranking Factors

The on-page search engine optimization factors are those under the webmaster's direct control. They are related to the site and page structure, to the web technologies involved in the implementation and design and generally to how the website is built. You can do about them, so it worths to keep them in mind before and while you develop your site. Please keep in mind the converse, of course, that when violated, some of these factors immediately jump into the negative on-page ranking factors domain.

The term "keyword" below refers to the "keyword phrase", which can be one word or more. Green rows confirmed by Google patent. Rows maked with are hot factors.

	Positive On-Page Factor	Brief Description
	Keywords	Google patent - Topic extraction.
	Keyword in URL	First word is best, second is second best, etc.
	Keyword in domain name	Same as in page-name-with-hyphens.
	Keywords in Header Tags
	Keyword in title tag	Keyword in Title tag - close to beginning Title tag 10 - 60 characters, no special characters The Florida Update EVEN penalized for this, as part of the OOP. That was absurd, but effective.
	Keyword in description meta tag	Shows theme - less than 200 chars. (Was part of Google Florida OOP) Google no longer relies upon this tag, but frequently uses it.
	Keyword in keyword metatag	Shows theme - less than 10 words. (Was part of Google Florida OOP) Every word in this tag MUST appear somewhere in the body. If not, it will be penalized for irrelevance. NO single word should appear more than twice. If not, it is considered spam. Google purportedly no longer values this tag, but others do.
	Keywords in Body Content
	Keyword density in body text	5 - 20% - (all keywords/ total words) Some report topic sensitivity - the keyword spamming threshold varies with the topic?
	Individual keyword density	1 - 6% - (each keyword/ total words)
	Keyword in H1, H2 and H3	Use H1 font style (Was part of Google Florida OOP)
	Keyword font size	In strong, bold, italic, etc.
	Keyword proximity (for 2+ keywords)	Adjacent is best
	Keyword phrase order	Does order in the page match order in the search query? Anticipate the query - match word order.
	Keyword prominence (how early in page/tag)	Most important at top of page, in bold, in large font.
	Keywords - Other
	Keyword in alt text	Should describe graphic - Do NOT fill with spam. Use keyword in the image file name. (Was part of Google Florida OOP - tripped a threshold - may still be in effect to some degree as a red flag, when summed with all other on-page optimizations).
	Keyword in links to site pages (anchor text)	Links out anchor text use keyword?
	Internal Links - Navigation
Site	To internal pages - keywords?	Link should contain keywords. The filename "linked to" should contain the keywords. Use hyphenated filenames, but not long ones.
Site	All internal links valid?	Validate all links to all pages on site.
Site	Efficient - tree-like structure	Two clicks to any page - no page deeper than 4 clicks.
Site	Intra-site linking	Appropriate on-topic links between lower-level pages.
	Outgoing Links - Navigation
	To external pages - keywords?	Google patent - Link only to good sites. Do not link to link farms.
	Outgoing link Anchor Text	Google patent - Should be on topic, descriptive.
	Link stability over time	Google patent - Avoid "Link Churn".
	All external links valid?	Validate all links periodically.
	Less than 100 links out total	Google says limit to 100, but readily accepts 2-3 times that number. Use rel-nofollow if you don't want to weaken your PR.
	Other On-Page Factors
	Domain Name Class	.edu seem to be given the highest status .org sites seem to be given high status .com sites excel in encompassing all the spam/ crud sites, resulting in the need for the highest scrutiny or action by Google. Perhaps one would do well with the new .info domain class.
	File Size	Do not exceed 100K page size. Small files preferred < 40K (lots of them).
	Hyphens in URL	Preferred method for indicating a space, where there can be no actual space. One or two = excellent for separating keywords. Four or more = BAD, starts to look spammy. Ten = Spammer for sure, demotion probable?
	Freshness of Pages	Google patent - Changes over time. Newer the better - if news, retail or auction! Google likes fresh pages. So do I.
	Freshness - Amount of Content Change	New pages - Ratio of old pages to new pages.
	Freshness of Links	Google patent - May be good or bad.
	Frequency of Updates	Frequent updates = frequent spidering.
	Page Theming	Page exhibit theme? General consistency?
	Keyword stemming	Stem, stems, stemmed, stemmer, stemming, stemmist, stemification...
	Applied Semantics	Synonyms, CIRCA whitepaper
	LSI	Latent Semantic Indexing - Speculation, no proof.
	URL length	Keep it minimized - use somewhat less than the 2,000 characters allowed by IE - less than 100 is good, less even better.
	Other On-Site Factors
	Tree Structure	Influences SERPs - logical, consistent, conventional.
	Site Map	The site map AND a Google Sitemap are a must-have if you are serious about website ranking. Combine it with other rules, like the usage of keywords in the anchor text.
	Site Theming	Site exhibit theme? Use many related terms? Have you used a keyword suggestion tool? A thesaurus?
	Site Size - Google likes big sites	Larger sites are presumed to be better funded, better organized, better constructed, and therefore better sites. Google likes LARGE sites, for various reasons, not all positive. This has resulted in the advent of machine-generated 10,000-page spam sites - size for the sake of size. For the same reason now fewer pages preferred, due to proliferation of computer-generated pages.
	Site Age - Old shows stability	Google patent - The older the better. Boost for long-established sites, new pages indexed and ranked easily. The opposite of the sand box.
	Age of page vs. age of site	Age of page vs. age of other pages on site.
