Can I make all the letters Bold that shows in the SERP's? And does it gi8ves any advantages SEO wise?

Tools like ahrefs, majestic and even SEmMrush ar good for finding links. But I see that there are many links that are shown by these tools which have gone dead months ago.

So, my query here is how to check the live link data of any site or domain? Say if I am purchasing one?

Note:- Useless backlink suggestion comments are not appreciated. And I will report the moderator to remove them from my thread.

So, one of my page was ranking pretty high in Google. It was moving around 2 to 6th position. It is  a good page with a great tutorial in our niche.

I tried to market it more a little bit. I published the article in medium. And all of a sudden my page got lost from the SERP's and only the page from medium is present. Why this happened?

Is it possible?

Is Fb ads a good choice for beginners to promote affiliate products?? Those who are starting their career as an affiliate marketer.

I mean to track the clients. And what not's about their taste and interest.

The reason I am asking this because recently I encountered with some marketers who were complaining about these cookie practices.

I was just wondering how do they monetize? They can't go for adsense that's for sure. Because most of these sites violates adsense policies.

Are the micro niche blogs still profitable these days?

I can build and sell them, right? Are they still around?

I hope my title is right and understandable.

Both pages should exist. Content is more or less same yet different to some point. How to get one of them to rank? Ofcourse the page of my choice.

Does a site's age and reputation gets counted when it comes to indexing backlinks?

I mean how fast they get noticed by Search Engines like Google and have their effect?
