hello all, I just wonder does google and yahoo has the same formula how they index website? Probably, it's the same but I am not sure, what do you think?
Thanks in advance

As per my experience I think they have different formula for that. Although if we do promotions after that they both index our site so you may think that both index in same manner.

I believe they have different algorithms that is also why the serp of a website is different.

No dear ! Both google and yahoo using different algorithm yet trying to bit each other, but considering for SEO ,we should think about google only, results will automatically improve on yahoo also.

different search engines have their own unique way of determining the site rankings and its importance - algorithms.. that's why you can be on top of Google rankings but sometimes low on Yahoo or Bing...

No yahoo and Google algorithm are different. so indexing way is different.

I think they index differently because my keyword ranks differently from google to yahoo.

I dont know their algorithms are different or not, their indexing way is different.

Both using different algorithms that s why search results are different in both of the sites

Actually their indexing is basically the same.

Software agents read the source code, store it in a database then analyse the page content.

However their ranking algorithms are completely different.

Look, in indexing Google works best than Yahoo believe me.

similar but ultimately different.

For me they are indexed differently Google has a lot of options than Google.

In terms of indexing, Google and Yahoo MIGHT just differ in some other way like indexing speed.

If they indexed in the same way, they will have the same result, one of them maybe not exist.

There are no SEs that are just same. Each SE has is own characteristic and system so I think there are still some difference on it.

Different algorithms. Different ways of looking at websites, and counting links. Most important difference is that Yahoo will count nofollow links as relevant, where Google will not. I wouldn't think too much about Yahoo though, as it's scheduled to be replaced with Bing on all fronts.

Thank you Chris. I was beginning to get a headache reading this thread until I saw your reply. Now I don't have to muti-quote every reply to straighten this out...phew!

Algorithms are totally different. Its hard to explain everything in here, but ITS DIFFERENT!

I think they have different formula to index.
