How to get high quality dofollow backlinks for your site for free
 

Search places in well indexed websites in which you can insert links (for example comments section, user bio ...etc), if the website adds automaticly rel='nofollow' attribute for the link tag this means it wont work, but if you inspect the link tag and you find that the website ignore adding rel='nofollow' this means that we can get a backlink if the page in which we inserted the link is indexed or indexable in future.

Example:
Go to pixabay.com
Create an account, and in your profile setting you will find an option to add your website, fill it, you will notice that when you access your profile link and you inspect your website link you wont find rel='nofollow' attribute.
Your profile link will be indexed soon by google and once indexed googleBot will also discover your website link, to make this happen fast try to comment at least three posts in pixabay.com so that your profile link will be discovered fast by crawling bots.
Congratulation you have got now a high quality backlink for your site from pixabay.

Sounds good.

Just done it, let's look what it's going to do for the :2 cents::2 cents:

Is it really a "high quality" backlink though? A backlink sure, but let's not stretch it and call it high quality.

That's cool that you're providing helpful information.
I'm not sure, though, if I'd necessarily call this profile link you describe "high-quality."

Just buy xRumer, GSA SER and/or Scrapebox if you want to get profile backlinks in bulk.

Probably kill your site(s), though, if you don't know what you're doing.

i would not call those high quality :2 cents::2 cents:

maybe if you were a popular user on the site, that will help
