Oct 08/2017 During the last video conference with webmasters Google rep called John Mueller said that Googlebot still refrains to scan HTTP.
The reason is that the crawler already scans the content that fast, so the benefits that the browser receives (web pages loading time is decreased) are not that important. We are still investigating what we can do about it.
Therefore, referential audits are needed if there were any violations in the history of the resource.
They are not necessary for many website owners and it is better to spend this time on improving the website itself, says Slagg.
I have it for 4 years already and I do not have a file named Disavow. 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.
