Google Ranking Factors - SEO Checklist
There are "over 100 SEO factors" that Google uses to rank pages in the Google search results
(SERPs). What are the search engine optimization rules? Here is the speculation - educated guesses
by SEO webmasters on top webmaster forums. Various confirmed and suspected Google Search
Engine Optimization (SEO) Rules are listed below.
Google Ranking Factor Checklist
The SEO Rules listed below are NOT listed by weight, and not by any presumed relevance - THAT exercise is left up to the reader!
Alleged POSITIVE ON-Page SEO Google
Ranking Factors (38)
(Keeping 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.

First word is best, second is second best, etc.
Keyword in Title tag - close to beginning Title tag 10 - 60
Keyword in title characters, no special characters The Florida Update EVEN
penalized for this, as part of the OOP. That was absurd, but effective.
Shows theme - less than 200 chars. (Was part of Google
description meta Florida OOP) Google no longer relies upon this tag, but
frequently uses it.
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.
5 - 20% - (all keywords/ total words) Some report topic

2+ keywords)Keyword phrase Does order in the page match order in the query? Anticipate
Most important at top of page, in bold, in large font
Should describe graphic - Do NOT fill with spam (Was part of
Keyword in alt 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).
Link should contain keywords. The filename "linked to"
should contain the keywords. Use hyphenated filenames, but
Validate all links to all pages on site.
Two clicks to any page - no page deeper than 4 clicks
Intra-site linking Appropriate links between lower-level pages
Google patent - Link only to good sites. Do not link to link
Google patent - Should be on topic, descriptive
Google patent - Avoid "Link Churn"
Google says readily accepts 2-3 times that
.edu seem to be given the highest status.org sites seem to be given high status
Domain Name .com sites excel in encompassing all the spam/ crud sites,
resulting in the need for the highest scrutiny/ action by Google. Perhaps one would do well with the new .info domain class.
Absolutely do not exceed 100K page size. Small files
preferred <40K (lots of them).
Preferred method for indicating a space, where there can be no actual space One or two= excellent for separating keywords
Hyphens in URL Four or more= BAD, starts to look spammy Ten = Spammer
Google patent - Changes over time Newer the better - if news,
retail or auction! Google likes fresh pages. So do I.
New pages - Ratio of old pages to new pages
Stem, stems, stemmed, stemmer, stemming, stemmist,
peculation, no proofKeep it minimized - use somewhat less than the 2,000
characters allowed by IE - less than 100 is good, less even better
Larger sites are presumed to be better funded, better
organized, better constructed, and therefore better sites.
Google likes big Google likes LARGE sites, for various reasons, not all sites
positive. This has resulted in the advent of machine-generated 10,000-page spam sites - size for the sake of size.
Age of page vs. age of other pages on site
Note: For ALL the POSITIVE On-Page factors listed above, PAGE RANK can OVERRIDE
them all. So can Google-Bombing.

The Florida update went after affiliates with a vengeance - flower and travel affiliates were hit
hard - cookie-cutter sites with massive inter-linking, but little unique content. Subsequent updates have also targeted affiliates.
OP) Penalty for over-compliance with well-
established, accepted web optimization practices. Since the Florida update, if you simply cannot
achieve top position, your only alternative to first page SERP exposure may be Google AdWords (you pay for exposure).
Don't link to link farms, FFAs (Free For Alls) Don't forget to check the Google status of
EVERYONE you link to periodically. A site may go "bad", and you can end up being penalized, even though you did nothing.
Don't immediately send your visitor to another
page other than the one he/ she clicked on.
Including the you can't say on TV, plus the 150 or so that followed. Don't shoot yourself right straight in the foot.
Also, avoid combinations of normal words, which when used together, become something else entirely - such as the word juice, and the word love.
"Links" in title tag, etc. Here is my listhis penalty has been
loosened - many of these words now appear in normal context, with no problems. But watch your step.
- within the same C block (IP=xxx.xxx.CCC.xxx) If you have many sites with the same web host, prolific cross-linking
can indicate more of a single entity, and less of democratic web voting. Easy to spot, easy to penalize.

- Google is now switching
between a "Newer" cache, and an "Older" cache,
frequently drawing from BOTH at the same time.
Page edit - can reduce consistency This was implemented to frustrate SEOers. Did
your last edit substantially alter your keywords, or theme? Expect noticeable SERP bouncing.
Problematic - know pitfalls - shorten URLs,
Don't use for redirects, or hiding linksMost (all-?) SE spiders can't read Flash content
Provide an HTML alternative, or lose out.
A red flag - one reason only - a sneaky link.

Based on the Number and Quality of links to you Google link reporting continues to display just a SMALL fraction of your
actual backlinks, and they are NOT just greater than PR4 - they are mixed.

Ranking Factors (13)
Have you paid a company for web traffic? It is probably low quality traffic, with a zero conversion rate. Some providers of traffic for traffic's sake may be considered
"bad neighborhoods". Can Google discount your traffic (for true popularity), because they know it's mostly phony? Have you read about
In a nut shell, old links are valued, new links are not. This
is intended to thwart rapid incoming link accumulation,
accomplished through the tactic of link buying. Just one of the sandbox factors.
Query meaning changes over time, due to current events
You MUST have at least 1 (one) incoming link (backlink)
from some website somewhere, that Google is aware of, to REMAIN in the index.
Link-buying (Very good Google patent - Google hates link-buying, because it IF you don't get caught, corrupts their PR model in the worst way possible. 1. Does
your page have links it really doesn't merit? 2. Did you get
caught, the penalty isn't tons of links in a short time period? 3. Do you have links worth it.)
Google promises to Ban! (Presenting one webpage to the
search engine spider, and another webpage to everybody else.)Google says that incoming links from bad sites can't hurt you, because you can't control them. Ideally, this would be
true. However, some speculate otherwise, esp., when other
neighborhoods, affiliates associated factors are thrown into the mix, such as web

Domain Hijacking (work COPYS your entire website, and HOSTS it elsewhere,

WMG is the worst offender - gobbles up tons of Google server time by nervous Nellie webmasters. Google even
mentions them by name. I think that Google will spank
you when you cross the threshold, of say, 100 queries per day for the same term, from the same IP. Google can block your IP. Get a Google API. What is your uptime? Ever notice a daily time when your server is unavailable, like about 1:30 AM? How diligent
must Googlebot be? This is the worst reason to get
dropped - you just aren't there! An ISP maintenance interruption can cause delisting.
. Bull! Google now has over 8 Gigs of indexed

huge websites, but I think that it is G just cleaning house, by dumping computer-generated pages.

Bouncing Ball Algorithm At least 2, and often 3 identifiable Google Search Algos
are currently in use, alternating pseudo-randomly through the data centers.
GOOD LUCK NOW on trying to figure things out! IN ADDITION, some the above factors are being "tweaked" daily. Not only are the "weights" of the factors changed, but the formula itself changes. Change is the only constant.
An algo change can boost or demote your site. I put this in the negative factors section, because your position is never secure, unless of course, you are huge (PR=7 or greater). If you simply cannot achieve top position, your only alternative to first page SERP exposure may be Google AdWords (you pay for exposure).
Today, I searched for an extremely competitive "2-word term", and I found that NOT ONE of the top ten Google SERPs had even one of the words on the page.
YOWSA!Today's theory - when it doesn't matter, anybody can get #1 in a second, if they know the on-page rules. BUT, after a certain "commercial competitive level", the "semantic analysis" algo kicks in, and less becomes more. The keyword density rules are flipped upon their noggins. I think that we are witnessing the evolution of search engine anti-seo sophistication, right before our very eyes. Fun stuff.

Notes to the Above 118 Google Ranking Factors:
1 I have tried to summarize the best opinions of many webmaster forum posters. 2 There are no published rules - this is my continuingly changing compilation of SEO chatter. 3 If your keywords are Rare and Unique, then Page Rank doesn't matter. 4 If your keywords are very Competitive, then Page Rank becomes very important. 5 The fewer incoming links that you have, the more important on-page factors are.
There are a million ifs, ors, buts . . . I am attempting a concise summary. Exceptions to EACH of the POSITIVE ON-Page factors are frequent and many. However, I feel that it is important to

I am referring to understatement, sometimes even to the point of confusion. "significant", "may", etc. For example, when Google states that maybe it might not

you are history". Some Google suggestions are actually commands (STRONG HINTS) in disguise. At some point, you begin to realize this. Google just can't tell us everything, literally. Soooooooooo, LISTEN UP! Read the rules. Read between the lines. Carefully.
