Density of the anchor text in backlinks

[serenoo]

What should be the density of my principal keyword in my backlinks?

Example:
My website is www.keyword1-keyword2.com and I want to get the top when someone digit on google:
keyword1 keyword2

As said in this forum now the rule is varying the anchor text in backlinks, that means I cannot take all backlinks with anchor
keyword1 keyword2. Then in % how many links pointing to my website with anchor keyword1 keyword2 do I have to get?

I assume by "density" you mean the keyword frequency across all the page's backlinks, or the backlink profile. Am I correct?

Coming up with an exact percentage may be a futile task. Google has not given us that information, it probably changes all the time, and I can't imagine the kind of network of test sites it would take to isolate and monitor the exact percentage. Add to this another factor - the website's trust rating in Google is almost definitely a factor that moderates how any percentage threshold is applied for spam detection.

The guideline here is that Google does not want to reward websites that control a great portion of their own backlinks. They are looking for a natural backlink profile, and they certainly have the data to know what that looks like. Stray too far from the statstical norm and those backlinks will stop helping and may even start to do damage.

In a natural profile, keyword anchor text must share space with a significant amount of "example.com", "business name", "Click Here", "Learn More", images with no alt attributes -- all of that and more.

We have a solid discussion about Natural vs. Un-natural - in SEO and the Google Algorithm [webmasterworld.com] in the Hot Topics area. It may help you why the search for a precise percentage is probably not worthwhile.

You guessed right. I was talking about the frequency.
I do not want the exact percentage, but an approximation.
Is it about 95%? or about 50%? or about 20%? or from 20% to 60%?
I know google of course do not say it, but I think with 95% of the frequency you are out. Aren't you?
Thank you for the link I am going to read it.

I think that the percentage threshold will also vary for a keyword domain name (clearly example.com would be common anchor text) compared to a branded domain name. But yes, 95% backlinks with the same keyword would be well over the natural threshold.

From what I've seen by analyzing backlink profiles, even seeing 50% of the same keyword as backlink anchor text would be too much (unless those anchors also use the ".com").

Since this factor might also vary by market niche, you probably would get a more specific idea of the tolerable range by analyzing the backlink anchor text of your top ranking competitors.

keyword1 keyword2
is considered different from
keyword2 keyword1

or it is the same anchor text?

[tedster]

My guess is that they're considered to be the same, but that is completely a guess - I've got no data or even anecdotal information for just one case.

If I already reached the 50% for keyword1 keyword2 do you think it is better to avoid
keyword1 word2 too?
(even if keyword1 word2 is less than 10%).
