set undetectable links?

[Affenmensch]

Hey Guys,

I was wondering if it is possible to set a link on a site, which can not be seen by the backlink tools. When you have a website, where no one should be able to see that a link is in the article (at elast not when using tools) and you remove it from the article once it has served his purpose. It should not be visible in historical analytics.

Are there ways for that?

Cheers

There are different ways to make this possible. It's difficult to see which could be better without knowing the purpose, but essentially I find two (there could be more):

1. By detecting the user agent of the crawlers before loading the site and presenting a different web to those specific engines
2. Most crawlers do not check javascript scripts, therefore, you could put the link after the site has loaded via javascript.

Thanks for your reply! I think #2 might be a good solution for me

Create and add the link using JS, put the JS into a seperate file and robots.txt block the file.
Use the async property on the JS script call so not to block and adversely affect your perf scores.

These are great suggestions.

Keep in mind, for #2, that some do load the javascript, so it's not foolproof. Another route would to block the backlink tool crawlers altogether in htaccess. (Don't do this in robots.txt, because crawlers aren't required to obey.)

Yes, I just thought about the same. And actually I would need a way to do it, without editing scripts. But I think it might be too much to ask. I have access to some websites and would be able to place links, but it is essential that no one would be informed, if developers or others. That makes it very difficult
