Yahoo search algorithm?

[mcgettrs]

Hi, does anyone know where i would find information on what algorithms yahoo uses for ranking pages. any help would be apprechiated

You wont find a perfectly written set of instructions for building websites or pages for Yahoo or any other search engines. SEO is based a lot on situational data, competition and specific domain issues. One set of rules does not work in SEO.

That being said I noticed a neat little article from Shawn Campbell (Red Carpet Web Promotion, Inc) basically he lists the major components to successful SEO. A ice list for newbie’s to review when launching their first SEO program.

McGettrs,

Yahoo works just like the other two main engines except its relatively biased towards "on page alignment".

For an explanation see:

Search engine algorithms (http://www.simplyclicks.com/Algochart.pdf)

Great figure David. Figured that out based on

1. Experience?
2. Theory?
3. Combinantion?

"f (ranking) = a1 x f (onpage) + a2 x f (offpage) ,

Where f (ranking) = function for Ranking,
f (onpage) = function calculating onpage factor value,
f (offpage) = function calculating offpage factor value and
a1 and a2 are approx weights".

There is a good figure in section 2 of that page too.

Kjell,

the key word is "relatively".

In recent months Yahoo appears to have gone more off page. But its still the most "on page" of the big 3.

See my thoughts on the algorithms:

Yes, it was the figure in that document I referred to.

PHP is like a preprosessor.

1. You may have PHP code in URL's.
2. You can switch in and out of PHP while coding HTML. "The selling message" of PHP?
3. You can write more or less Search Engine-Friendly URLs (http://www.sitepoint.com/article/search-engine-friendly-urls)
</digression>

Are you working on that as part of your SEO? We now know so much / little about the alogrithms, that that should be the next field to dive into.

In short PHP coding and SEO?

Query strings etc. etc.

Kjell,

I've a knack of getting top rankings with Yahoo. Probably a few hundred for various clients in a number of categories. Seems they like my logic. I call it alignment.

mcgettrs,
nobodyelse may know exactly what algorithm yahoo or other search engines are using except themselves.
at best, we may guess the factors that weight more for different search engines

[dburdon]

Crush123,

I'd agree that nobody can know the exact Yahoo algorithm. However a track record of top rankings across a range of sites and categories has shown the importance of several factors.

dburdon -

Thanks for sharing the Algo chart - great stuff!

SEOforGoogle,

the algo chart is looking a little dated now - but it has stood the test of time.

We can't know yahoo's algo, but i think we can follow GG webmaster's guidelines to develop site.
