How to block Ahrefs and MajesticSEO on my website?

I've read here on BHW that in order to avoid a Google manual penalty, it is good to block Ahrefs and MajesticSEO on your website. I wonder how can I do that?

Also, which other tools should I block as well? Backlinkwatch.com? Any other tools?

And should I block these tools only on my money website or on my PBN blogs, too?

Block them on your PBN blogs only.

You don't need to block bots for money sites.. You can make use of them to check backlinks and track keywords by the tools. But You should do it for PBNs to not be caught by other bots that will definitey make a way to get it banned.

I own over 80+ PBN, and i block all of them AHrefs, Majestic, OSE etc.


Why block ?


#1 To Prevent Spam - There are people out there who buy links and build ‘spammy' keywords stuffed with tier 2 links to them. This is because they do not owe that PBN — hence, they have the mindset that they could spam tier 2 links with GSA in order to increase the PA of that page. And when they do that, it is going to jeopardize the entire domain for ‘spammy' anchor text. Resulting in deindex, and having your money spent down to the drain.


#2 To Prevent Being Too Public - Let's say that in a scenario that we have 50 clients, and we give out 50 reports. All 50 people are going to have the live links, and it's no longer going to be private. Why do I say that? This is because in a hypothetical case that everyone has the live links, some might just share them around. And presuming that one of them is a jealous white hat guy (or maybe even a spy from Google), reporting the links to Google could result you in having your rank drop and receiving a manual penalty.


#3 To Prevent Stealing Of Niche - Due to the fact that your main keywords and URL of your money site will be displayed on the live link report, if the link report becomes public, everyone can see what you are ranking for. And that is when they could start stealing your niche! Can you imagine your time spent doing keyword research is now free for public?


#4 To Prevent Negative SEO - To add on to the above factor, the moment that they steal your niche is the moment when they can start sending you 100k of GSA links to your money site. Your ranking will drop, and they will rise. Now... Imagine losing your money site just because you wanted a live link report.
