Advanced list of quality score factors

[Elric99]

Does anyone know of a list of advanced quality score factors such as how loading times, server location, cookie setting and other things not often discussed can be found?

Thanks

I believe a few of them are:

Position of the orion in the night sky, what's for lunch at the googleplex, the output of a magic 8 ball, the flight of birds....

Google has always said that the main factor of QS is CTR. I'm sure the weight can and probably does change from time to time. Google has never to my knowledge said how big of a factor it is (there are some hints) but it seems to be about 65%.

Next is keyword relevancy which is estimated at around 25%. I believe this factor to be basically a go/no-go. So if your keyword is relevant, you get a 100% score on that portion, otherwise you get nothing.

The final 10% is other factors. The only one to my knowledge that was made public is landing page loading time. For all I know, the whole 10% is given to loading time. It may be that half of it is with the other half (or 5% of the total QS) for other things. Some believe you need a policy page and an "about us" page.

All in all, QS simple and straight-forward with two major factors and a handful of others.

Hi

There is a youtube video from Google about how the quality factor (QF) is calculated. In this video Google sais that 2/3 comes from CTR!

As I recall, it doesn't say that 2/3 of QS is from CTR. It is implied however from the relative size of the pie charts.

There has to be an overriding deviation on the CTR based on display position, or only position #1 have a good QS.

We know that the lower the placement, drastically lower the number of clicks.

So if an ad was at position #6(below fold) we would expect it to have less clicks, but it may have a higher CTR for the "real" views that occur.

Google does take position into account. You can have a QS of 10 in any position. It is a relative value based on how good your CTR is compared to the historical average at that position.

"You can have a QS of 10 in any position."

True, but unlikely. Also i've seen that the relative for CTR is a bit wonky. I've personally had trouble maintaining high quality scores in positions 5-10, but tend towards better QS is 1-5.

> True, but unlikely.

I beg to differ. I can show you may QS10 at pretty much all positions. I can even show you some keywords with QS10 with CTRs under one percent.

I can definitively say that achieving a QS of 10/10 from the tenth or eleventh position is not difficult. I currently have thousands of keywords that are there now.
