Why some backlinks stay invisible for marketing tools?

Hmmm, maybe Google thought that your link is a spam...? For which website do you have this problem?

This constantly happens with Bitcoin game

I would say that your website is listed in spam area, because other explanation I do not see. Majestic is in my marketing tool kit, but for me everything works properly

What methods are you using to get your backlinks?

It's simple.

Scraping the web is expensive.

Most people probably don't realize, Google has server farms all over the world, HUGE server farms that each cost millions of dollars to build, run, update, scrape the web.

Sites like Majestic don't even have a small fraction of Google's budget to scrape the web.

I would put backlinks on more websites and build wide.

Every third party software out there, no matter how good people think it is, works by sending out its own bots that are scanning through the web and finding the information they are looking for.

There are countless amounts of websites out there with even more links between them. It is close to impossible for a bot to scan everything and find every single backlink that exists.

With time, they may show up on the list but it almost never happens.

Once the link has been created, it is already doing its job by sending over relevant traffic to your site. Regarding the ranking influence, it sometimes takes several months for a link to fully "kick in" and bump the site up.

Continue working on building up your online presence until you achieve rankings that you like. If you are in competitive niches, you probably going to have to do some continuous maintenance to stay up there.

Don't worry whether your backlink shows up in majestic or semrush or ahrefs.

Good luck and enjoy the process.

Are you sure they are "dofollow"?
