Concept flowing intoGoolges Page Rank
How Google probably does it ...

Does our brain work like google?http://www.world-science.net/exclusives/071205_google.htm

Psychological Study: Which words are strongly assotiated with each other?Using word assotiation test psychologists found outthat Google Page rank model predicts assotiations better than other models

3. Final results are calculated using weight given by basic ranking multiplied by the PageRank (which is between 0 and 1 always) for the particular page.Ex. The weight of result page A was 2 but pagerank was 0.2 and weight of result page B was 1 but pagerankwas 1 sorting would be B, A (1, 0.4). Without pageranksorting would be A B (2, 1).

2. Each page rank is calculated based on incoming and outgoing links

Outgoing and ingoing the page rankis subdivided betweenthe number of links flowingfrom page (100 links= 10% each)

1. Each page is split into array of words and each word is weightedfor the document.

Rare words have more weightthan common words

Keywords matching Search Query

=weight of page

Quality of Links

The higher the link relevance, the betteri.e. the link is called hamster food

The higher the Popularity of the page the link is coming from, the betteri.e. the page is often selected from the organic search page

"the quality of the inbound links to your website, in most cases, will be moreinfluential with the search engines than the content of your website itself."

The higher the Weigthting of the page the link is coming from, the betteri.e. the page contains the word hamster food

Quantity of Links

The more linksleading to your page the better

Page rank sorts the results on thesearch results page: The more page rankthe higher on the organic search list
Factors thatdetermine "Page Rank" (=quality of site or pagefor search terms)
So now now that you've got a good rank/ visbility ...

"If you’re selling products that are available elsewhere, you can get a lotmore attention and traffic by providing such valuable resources as reviews,independent testing, and side-by-side or feature comparisons"

Does your search result text attract users?

Match users searchbehaviours by either ...

Be a link on the"authority page"

Be yourself an "authority" in the subject = high rankingin Googles Organic Search

Off Page (Indirect Control)= more influentialthen OnPage factors

User Experience/User Satisfaction

Tagged by by Social BookmarkingServices?

Do users returnto search result page?

Other Websites

Pages linking to you

Their popularity / relevance forthe subject

The text of the linkitself ... buy hamsterfood

special term is called"link reputation"

the text in the article that contains the link

Ex: Hamsterfood on Hamster Sitebetter than link from non Hamser Site

How many other pagespoint to your site

On Page (dirct control)

Correct/ Standard programmingensures readability by Spiders

Images without "alt" tags are problematic

Keyword Postion makes asite more relevant: "Where" is thesearch term

Heading, Page Titlemust promote search termsthe page is optimized for

Meta Tag "Description"

... not important for Google

Headers

Must be "bold"

Maching of Search Term

Page Titles

Precise Matchingof Search Terms

Basic Tech Functioning

Back End
Webcrawler

Indexing the a website(=following Links) and copyingcontent to index of a page.

Front End
Search Engine Software

Problems: Being up to date /"live"

Spurious Results

Therefore Keywords searched forshoud be found in the same paragraphmake it a relevant page.

Size and Time

Solution: Crawl only top noch 15-20% of the web every day - rest every two weeks

Dynamically created pages

More and More pages

Updates: Frequent updates (i.e. News pages)

Determining Relevance

Concept of Factors
By ON-Page Factors

Other problems(repetitions and cheating)

Repetition

MetaTags

Headlines

Words in Headlinesare very relevant - Keywordsshould appear in the headline

Important for relevance are onlylarge headlines (h1 h1)

Sol. Use

Überschrift

in html code but control headlines in CSS

Repeated keywords are treated as Spam

Sol: Write individual keyword per page

Sol: Don't repeat

The description is usually shown beneath thesearch results title. If no description tag isfound then other info is taken.

Worte, für die Ihre Seite optimiert werden soll, müssen in der Beschreibung enthalten sein. Die Worte müssen sich auch im Seitentitel, den Keywords, dem Seitentext,... wiederfinden

Often the navigation is the item first read bysearch engines. Then this is what is diplayed

However not with Google or Bingwho ignore the description Tag.

If not filled out, the firt paragraph is used where the keyword is found in

Meta Tag Keywords (whichare however ignorde byGoogle)

Case specific search

Sol: Use correct case

Only Main Keywords are supplied for which we have many contenders

Sol: Create specific pages for users highly used combinations?

Sol: Check with Google Key wordstool for alternative kombinations

Sol: Use specific kombined keywords i.e. Mafo Nürnberg

Keywords are not linked

Sol: Link key words alternatively

User use differnt keywordsfor a page

Sol: Keywords can also contain synonyms (eBusiness instead ofE-Buisness)

use of same keywordsfor different pages

Sol: Write content first, then takekeywords from content

Sol: Keywords that describe site purpose bestcan be used on every page to increase impression ofusefulness of page

Sol: Every page needs individual keywords

Content

repeating paragraphsaccross different pages

i.e.overview pages

Sol: "follow, noindex" tag

using spelling or termsthat users wouldn't use

same titles for several pages

Title apperas as first line insearch engine

Sol: Every page needs individual title

Non-descriptive titels

Make users wonder if thepage is relevant

Sol: Make titles relevantto page content

Problem of 2 equal domains: www. and no www

Sol: Permanente Umleitung einrichten

Cheateing?: use of too many(the repetition) of search words

Sol: Avoid Repetition

Cheating: False Keywordsto increasevisibility / page rank (i.e. Sex Sex Sex Money Money etc.)

Due to fake keywords Google will not look here?

Technical quality

Links cant read because theyare graphics

Sol: Use alt tags

double domain (www or non- www)diminishes valu of both

yes

Bad Programming?

other tools show programming errors

Check: https://www.google.com/webmaster

Indexing: How many pages of thesite are indexed?

How many urls of mydomain has google savedsite:psyma.com

Prob: Google saved allmain links but not usability

solutions

sol: create glossary

sol: create dynamic sitemaps

not recognized by google

sol: give no follow to human links (i.e. impressum)other links will become more strong

Not enough deep links

Internal solutions

Use "Similar pages"

customer who saw this also saw that

sol: keep creating content

Too many overview pages

Sol: Flat site strucure

unclear what the problem is

sol: create rolling sites

sol: do internal deep linking

sol: get more inbound links

Psyma is ranked .... even if you search for "international market research"

Its not that "I'm numberone for this keyword" ...

Quality of Landing page:

usability

not really tested

use of keywords

not enough of the right ones

not enough compared to comp.

Integration of (previsously checked) important (=high volume or qualified) Keywords

Overall strategy: optimize pages from users perspective aking:what keywords would the use?

integrate alternative versions of keyword (i.e. ebusiness)

plural

singlular

in tags

in links

in header

in title

optimize pages for single, not for manykeywords

"international qualtiative market research" (start page)

i.e. "usability testing"

embed (high volume )keywords in text

Keyword Concepts

What are websites goals?

Conversion

Usabilty - lead users to relevant content

no testing

Attract only qualified users,too many users cost too much

Landing page optimization

unclear

Traffic

Ad has high rank

use google ads

Branding

Appear often in searches on top ranks

sol. use google ads

Psyma goal not specified

Long Tail

Use (rare)combinations

more probable to getfew but qualified users

"user experience optimization"

Single

Hight Potentials

Many competitors or get lucky

... but which Keywordsdo users use?

Check google adwords tool

Check for other related and hight ranked terms

Best may be combination offew competitors and highsearch volume

Check competitors

Check keyword tools

i.e. seaquake

Check Competitors keywordskeyword density using seaquake

Do internal keywordstormingfor Target group

let users make suggestsion

unlcear

Clickthrough Rateof search results

How good is the "scent"of information created by the data retrieved by Google search (a) Title b) Description )

Determined by descriptivnessof Title, Description Tag and Content

ebusiness research tell about frank knapp

Psyma.com has empty description tag

Google statisticlyknows what kind of descriptiontexts are most clicked when usersused specific keyewords

Googles concept of Signals
"Signals" determine how high site appears on the retruredsearch list

Non Google

Other search engines also pay attn. to meta tags

items receive more weighting

Frequency of words searched for:Words repeated several times

Beginning words of the content

MetaTAGs etc.

Meta Tags

Keywords

Description

Title

Name of URL(i.e. usability.de)

Google's Search Rank(200 Variables!?)

Google Page Rank (how important is this page in general)

the real page rank=recursive algorith:

Qualtiy and Quantity of Linkspointing to your page

Quality: How many and howimportant are those pages

Quantity: How many

ToolBar that supposedly tells how valuable a linkfrom that site is - however this is doubted and the rank shown is notup-to-date (3to4 month) while real value is updated daily

Another form of payment is link exchange Two PR4 links for one PR7

Companies however pay money based on that toolbar rating ("I will pay less"for my link on your page because your rank hasdropped)

Pay Sites high on Goolge listList URL money for Usability link to our page

Determine quality of visitors on a certain page (prepared to buy?)

Determine Importance of Pages in whole site

Rank titles of several pages using google

Determine Important pages

Page rank from search words
