Welcome to WebmasterWorld Guest from 220.127.116.11
My question is,
Search engines like Google whose efficiency largely depends on the Page rank apart from its algorithm...I feel they in a position of what to do next? because after exploitation of link building strategy by various means like link trading, article submission, forum posting etc....they had to devalue the Page Rank factor....Now they cannot make it zero completely because this Page rank is the thing which sustains the stability of ranking and make sure that SERP results are not changing overnight by keyword manipulation ....but anyhow it doesnt helps much in giving the better results....what search engines are thinking do thay have plan B?
Working out how long people stay on a site, how many pages they look at, how often they return.
In other words stickability and user experience. They can match that up with relevance and a sprinkling of link value (they can get much better at that too when they work out which links actually produce traffic) Thats the future
The fact is it's the same as it's ever been - the challenge is finding more and more ingenious ways of measuring it.
All they've ever wanted to show are the most relevant and best quality set of results for a given search term. There analytics penetration will eventually give them that I'm sure.
What's easier to do if one's goal is to "game" Google?
- create a webpage with a link?
- create some-"thing" clicking on links, staying on pages for a certain amount of time, etc?
User metrics isn't realistic... Billions of dollars poured into "AI" that will determine the usefulness of a page according to EACH indvidual term's value to a searcher?
Forget billions, let's try Trillions of dollars on a unpredictable technology that will probably not be any more "accurate" than PR?
As I've said before, a user-metric based algo would be an ambitious/borderline-crazy goal for Google '96, brainstormed college project by 2 of the most brilliant minds on the planet.
It's simply a laughable goal for Google 2008-?, a publicly traded company that has monetary responsibilities Google '96 did not, and missing the 2 brilliant minds.
As Churchill said,
"Democracy is the worst form of government, except all the others that have been tried"
"The PR algo is the worst form of Search engine, except all the others that have been tried"
Not to mention -
2 brilliant minds is always > 10,000 semi-geniuses
when it comes to true innovation.
