Using our free SEO “Keyword Suggest” keyword analyzer you can run the keyword analysis “Pea Agar” in detail. These are top keywords linked to the term “Pea Agar”. When you mention Google’s quality algorithm, how many algorithms do you use? Usually we do not talk about how many algorithms we use.
We publicly state that we have 200 factors when it comes to scanning, indexing and ranking. Generally, the number of algorithms is a casual number. For instance, one algorithm can be used to display a letter on the search results page. Therefore, we believe that counting the exact number of algorithms that Google uses is not something that is really useful . From this point of view, I can’t tell you how many algorithms are involved in Google search.
Since Google Penguin was modified into real-time update and started ignoring spam links instead of imposing sanctions on websites, this has led to a decrease of the value of auditing external links. According to Gary Illyes, auditing of links is not necessary for all websites at the present moment. I talked to a lot of SEO specialists from big enterprises about their business and their answers differed. These companies have different opinions on the reason why they reject links. I don’t think that helding too many audits makes sense, because, as you noted, we successfully ignore the links, and if we see that the links are of an organic nature, it is highly unlikely that we will apply manual sanctions to a website. In case your links are ignored by the “Penguin”, there is nothing to worry about.
I’ve got my own website, which receives about 100,000 visits a week. I have it for 4 years already and I do not have a file named Disavow. I do not even know who is referring to me. Thus, in the case when before a website owner was engaged in buying links or using other prohibited methods of link building, then conducting an audit of the reference profile and rejecting unnatural links is necessary in order to avoid future manual sanctions. It is important to remember that rejecting links can lead to a decrease in resource positions in the global search results, since many webmasters often reject links that actually help the website, rather than doing any harm to it. Therefore, referential audits are needed if there were any violations in the history of the resource.
