"Strong is treated the same as bold, italic is treated the same as emphasis" . . . Matt Cutts July 2006

-

10

Keyword proximity (for 2+ keywords)

Directly adjacent is best

-

11

Keyword phrase order

Does word order in the page match word order in the query?
Try to anticipate query, and match word order.

-

12

Can be important at top of page, in bold, in large font

-

Keywords - Other

-

13

Keyword in alt text

Should describe graphic - Do NOT fill with spam
(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 optimization - total page optimization score - TPOS).

-

14

Keyword in links to site pages (anchor text)

Links out anchor text use keyword?

-

NAVIGATION - INTERNAL LINKS

SITE

15

To internal pages- keywords?

Link should contain keywords.
The filename "linked to" should contain the keywords.
Use hyphenated filenames, but not long ones - two or three hyphens only.

SITE

16

All Internal links valid?

Validate all links to all pages on site.
Use a free link checker. I like this one.

SITE

17

Efficient - tree-like structure

TRY FOR two clicks to any page - no page deeper than 4 clicks

SITE

18

Intra-site linking

Appropriate links between lower-level pages

54

-

NAVIGATION - OUTGOING LINKS

55

19

To external pages- keywords?

Google patent - Link only to good sites. Do not link to link farms. CAREFUL - Links can and do go bad, resulting in site demotion. Unfortunately, you must devote the time necessary to police your outgoing links - they are your responsibility.

56

20

Outgoing link Anchor Text

Google patent - Should be on topic, descriptive

61, 62

21

Link stability over time

Google patent - Avoid "Link Churn"

-

22

All External links valid?

Validate all links periodically.

-

23

Less than 100 links out total

Google says limit to 100,
but readily accepts 2-3 times that number. ref 2k

-

121
(added)

Linking to Authority

Some say this gives a boost -
Others say that is absurd. However, it certainly is the opposite of linking to trash, which WILL hurt you.

-

OTHER ON-Page Factors

-

24

Domain Name Extension
Top Level Domain - TLD

.gov sites seem to be the highest status
.edu sites seem to be given a high status
.org sites seem to be given a high status
.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.<update> - Nope. Spammers jumped all over it - no safe haven there. Not so much, now - .info sites can rank highly.

-

25

File Size

Try not to exceed 100K page size (however, some subject matter, such as this page, requires larger file sizes).
Smaller files are preferred <40K (lots of them).

-

26

Hyphens in URL

Preferred method for indicating a space, where there can be no actual space
One or two= excellent for separating keywords (i.e., pet-smart, pets-mart)
Four or more= BAD, starts to look spammy
Ten = Spammer for sure, demotion probable?

6, 7
12, 13

27

Freshness of Pages

Google patent - Changes over time
Newer the better - if news, retail or auction!
Google likes fresh pages. So do I.

8, 9

28

Freshness - Amount of Content Change

New pages - Ratio of old pages to new pages

27

29

Freshness of Links

Google patent - May be good or bad
Excellent for high-trust sites
May not be so good for newer, low-trust sites

-

30

Frequency of Updates

Frequent updates = frequent spidering = newer cache

-

31

Page Theming

Page exhibit theme? General consistency?

Keyword stemming

Stem, stems, stemmed, stemmer,
stemming, stemmist, stemification

-

33

Applied Semantics

Synonyms, CIRCA white paper

-

34

LSI

Latent Semantic Indexing - Speculation, no proof

-

35

URL length

Keep it minimized - use somewhat less than the 2,000 characters allowed by IE - less than 100 is good, less is even better

-

OTHER ON-SITE Factors

5

36

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. Google has caught on and dumped millions of pages, or made them supplemental.

4

37

Site Age

Google patent - Old is best. Old is Golden.

3

38

Age of page vs. age of site

Age of page vs. age of other pages on site
Newer pages on an older site will get faster recognition.

NEGATIVE
ON-Page SEO Factors

Brief Note

BAD

39

Text presented in graphics form only
No ACTUAL body text on the page

Text represented graphically is invisible to search engines.

BAD

40

Affiliate site?

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.

BAD

41

Over optimization penalty (OOP)

Penalty for over-compliance with well-established, accepted web optimization practices. Too high keyword repetition (keyword stuffing) may get you the OOP. Overuse of H1 tags has been mentioned. Meta-tag stuffing.

BAD

42

Link to a bad neighborhood

Don't link to link farms, FFAs (Free For All's)
Also, 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. For instance, some failed real estate sites have been switched to p0rn by unscrupulous webmasters, for the traffic. This is not good for you, if you are linking to the originally legitimate URL.

BAD

43

Redirect thru refresh metatags

Don't immediately send your visitor to another page other than the one he/ she clicked on, using meta refresh.

BAD

44

Vile language - ethnic slur

Including the George Carlin 7 bad words 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 l0ve. See why I wrote that zero? I don't even want to get a proximity penalty, either. Paranoia, or caution? You decide. I always want to try to put my "best foot forward".

BAD

45

Poison words

The word "Links" in a title tag has been suggested to be a bad idea. Here is my list of Poison Words for Adsense. This penalty has been loosened - many of these words now appear in normal context, with no problems. But watch your step.

BAD

46

Excessive cross-linking

- within the same C block (IP=xxx.xxx.CCC.xxx)
If you have many sites (>10, author's guess) 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.
"This does not apply to a small number of sites" .. (this author guesses the number 10, JAWG) . . . "hosted on a local server". . Matt Cutts July 2006

BAD

47

Stealing images/ text blocks from another domain

Copyright violation - Google responds strongly
if you are reported. ref egol
File Google DMCA

BAD

48

Keyword stuffing threshold

In body, meta tags, alt text, etc. = demotion

??

49

Keyword dilution

Targeting too many unrelated keywords on a page, which would detract from theming, and reduce the importance of your REALLY important keywords.

??

50

Page edit - can reduce consistency

Google patent -
Google is now switching between a "newer" cache, and several "older" caches, frequently drawing from BOTH at the same time.
This was possibly implemented to frustrate SERP manipulators. Did your last edit substantially alter your keywords, or theme? Expect noticeable SERP bouncing.

6 - 7

51

Frequency of Content Change

Google patent - Too frequent = bad

32, 33

52

Freshness of Anchor Text

Google patent - Too frequent = bad

??

53

Dynamic Pages

Problematic - know pitfalls - shorten URLs, reduce variables (". . no more than 2 or 3", M.Cutts July 2006), lose the session IDs

??

54

Excessive Javascript

Don't use for redirects, or hiding links

??

55

Flash page - NOT

Most (all-?) SE spiders can't read Flash content
Provide an HTML alternative, or experience lower SERP positioning.

??

56

Use of Frames

Spidering Problems with Frames - STILL

-

57

Robot exclusion "no index" tag

Intentional self-exclusion

-

58

Single pixel links

A red flag - one reason only - a sneaky link.

-

59

Invisible text

OK - No penalty - Google advises against this.
All over the place - but nothing is ever done. (The text is the same color as the background, and hence cannot be seen by the viewer, but can be visible to the search engine spiders.) I believe Google does penalize for hidden text, since it is an attempt to manipulate rank. Although they don't catch everyone.

-

60

Gateway, doorway page

(I see changes here - not only does the doorway page disappear, but the main page gets pushed down, as well - this is a welcome fix.)

OK - No penalty - Google advises against this.
Google used to reward these pages.
Multiple entrance pages in the top ten SERPs - I see it daily. There they are at #2, with their twin at #5 - 6 months now. Reported numerous times.

-

61

Duplicate content (YOUR'S)
Duplicate content (THEIR'S) below (Highjack)

OK - No penalty - Google advises against this.
Google picks one (usually the oldest), and shoves it to the top, and pushes the second choice down. This has been a big issue with stolen content - the thief usurps your former position with YOUR OWN content.

-

62

HTML code violations
(The big G does not even use DOCTYPE declarations, required for W3C validation.)

Doesn't matter - Google advises against this.
Unless of course, the page is totally FUBAR.
Simple HTML verification is NOT required (but advised, since it could contribute to your page quality factor - PQF).

-

-

Since the above 4 items are so controversial, I would like to add this comment:
There are many things that Google would LIKE to have webmasters do, but that they simply cannot control, due to logistical considerations. Their only alternative is to foment fear and doubt by implying that any violation of their "suggestions" will result in swift and fierce demotion.
(This is somewhat dated - G is fixing these things.)

IN GENERAL, this works pretty well to keep webmasters in line. The fallacy of this is that attentive webmasters can readily observe continuing, blatant exceptions to these official pronouncements.

There are many anecdotes about Goggle "taking care" of a problem. Google states that they do not provide hand-tweaked "boosts", but are silent about hand-tweaked demotions. They occur, for sure. To believe otherwise is naive. Wouldn't YOU swat the most obnoxious flies? I would.

It is becoming easier to determine the best thing to do. Try to avoid any Google penalties or demotions.

-

119

Phrase-based ranking, filters, penalties

Feb. 2007 - Google patent granted. Do not use phrases that have been associated and correlated with known spamming techniques, or you will be penalized. What phrases? Ahh, you tell me.

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.

Total incoming links ("backlinks")

Historically, FAST counted best (www.alltheweb.com).
No more - Yahoo (parent) broke it.

Current TYPICAL Backlink Reporting Ratios -
Google - 30 links
MSN - 1,000 links
Yahoo - 3,000 links

-

65

Incoming links from high-ranking pages

In 2004, Google used to count (report) the links from all PR4+ pages that linked to you. In 2005-2006, Google reported only a small fraction of the links, in what seemed like an almost random manner. In Feb. 2007, Google markedly upgraded (increased) the number of links that they report.

DMOZ Sucks Discussions
DMOZ Problems Discussions

The Google Directory is produced by an unknown, ungoverned, unpoliced, ill-intentioned, retaliatory, monopoly enterprise, consisting of profiteering power-ego editors feathering their own nests - the ODP. AOL is making millions, and needs to police it's run-amok entity. Enough already!

This is a tough one.
Google's directory comes STRAIGHT from the DMOZ directory. You should try to get into dmoz.
But you can't.
Be careful whom you approach with the old spondulix -
Formal DMOZ Bribe Instructions.
It is almost impossible to get into DMOZ. This site cannot get in, after waiting over 2 YEARS (33 months). Not even in the lowest, most insignificant category, "Personal Pages". I guess I just don't "measure up" to the other 20,000+ sites in the personal category.
I'm not the suck-up type - I kissed them off long ago. What a waste of time!

UPDATE: This page (not site) finally got indexed in June 2007, thanks to a legitimate editor. No money was paid.

Google needs to DO SOMETHING about populating its own directory with the skewed, incomplete, poorly determined results from the dysfunctional Open Directory Project - the ODP!

(added)

Traffic Buying

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 Traffic Power?

22-29

106

Temporal Link Analysis

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.

18

107

Change of Meanings

Query meaning changes over time, due to current events

BAD

108

Zero links to you

You MUST have at least 1 (one) incoming link (back link) from some website somewhere, that Google is aware of, to REMAIN in the index.

BAD

109

Link-buying

(Very good IF you don't get caught,
but don't do it -
when caught, the penalty isn't worth it.)

Google patent - Google hates link-buying, because it corrupts their PR model in the worst way possible.
1. Does your page have links it really doesn't merit?
2. Did you get tons of links in a short time period?
3. Do you have links from high-PR, unrelated sites?

41, 42

110

Prior Site Ranking

Google patent - High = Good

BAD

111

Cloaking

Google promises to Ban! (Presenting one webpage to the search engine spider, and another webpage to everybody else.)

??

112

Links from bad neighborhoods, affiliates

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 associated factors are thrown into the mix, such as web rings.

BAD

113

Penalties - resulting from
Domain Hijacking
(work with Google to fix)

Should result in IMPRISONMENT, forthwith!
Grand Theft, mandatory minimum sentence.
The criminal COPIES your entire website, and HOSTS it elsewhere, with . . . a few changes.

-

114

Penalty - Google TOS violation

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.

??

115

Server Reliability - S/B >99.9%

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..

-

116

No more room
Pages being dropped from large sites

The 2³² problem - Google has hit the 4.3 Gigabyte address space wall. Bull! Google now has over 8 Gigs of indexed pages.
Thousands of pages are disappearing from various huge websites, but I think that it is G just cleaning house, by dumping computer-generated pages.

117

Rank Manipulation by
Competitor Attack

(1. Content theft causing you to get a duplicate content penalty, even though your content is the original - Google has problems tracking original authorship. People are still stealing my content, but nobody trumps me (in Google) with my own content - hats off to Google.)

Examples -
Site-Wide Link Attack
and
302 Redirect Attack
and
Hijacker Attack

Impossible by Google definition (except for a few nasty tricks, like making your competition appear to be link spammers)
Ideally, there SHOULD be nothing that your competition can do to directly hurt your rankings.

However, an astute observer noticed that Google changed their website to read :
Old verbiage = "There is nothing a competitor can do to harm your ranking ..."
New verbiage = "There is ALMOST nothing a competitor can do ..."
An obvious concession that Google thinks that at least some dirty tricks work!

Of course, there will always be new ones!

-

118

Bouncing Ball Algorithm

At least 2, and often 3 identifiable Google Search Algos are currently in use, alternating pseudo-randomly through the data centers.
G has moved to a daily dance. Multiple changing factors are applied daily. 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 Ad Words (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.
