What are the DIfferent Methods of Backlinks?

Today Wanna Write About The Types of Backlinks...

All backlinks would primarily fall into two categories:

1) Earned Backlinks
2) Acquired Backlinks

Earned Backlinks

The links that search engines would like you to have are the links you earn, the ones you naturally get. These type of links are usually the result of great branding, being newsworthy, producing great content, giving out stuff for free, etc. To earn links, you need to do things that'll make people want to talk about you or reference you for some reason. Also, you can't typically plan to earn links, it would be a by product of good marketing, branding and content.

Examples:

1. Content Creation + Promotion: When doing a search for link building strategies online, you'll often come across this point of "create great content". That alone is not enough unless you do enough to promote it. You need to actively promote it among your existing subscriber base, on your social channels, advertise it (for an initial boost), comment on related blog posts referencing it in some way, etc. Only when it's been effectively promoted is there a chance for it to be linked from some blogger who finds it interesting enough to reference from within his article.
2. Info-graphic Creation + Promotion: You could create an info-graphic that people would find interesting enough to embed on their sites. Of course again, it needs to be promoted to be successful.
3. Interviewing Prominent Individuals + Promotion: When you interview a prominent personality and publish such an interview, there is some likelihood that the keen followers of this personality would link to this interview. Then of course again, this needs to be promoted and would be good if you influenced the personality interviewed to also promote it among his follower base.
4. Useful Free Tool + Promotion: A common example is that of a Loan Calculator that is used by some real estate sites. Since these sites offer a free loan/mortgage calculator, the people writing about real estate are likely to reference such a resource to their readers when the context requires it. And again, it's necessary to promote the tool. Awareness is required before people begin to reference it.

The primary concept behind the strategy of earning links is:

Create an asset or take an existing asset. The asset could be a piece of content, a tool, an info-graphic, an existing contest you're running, a PR piece, a video, ... Market that asset and reach out to possible influencers about sharing it. Repeat the process for each asset. 

It takes time. It takes persistence. You will earn links only on deserved assets and sometimes you won't get that as well ;) So it's just important to be persistent with continued quality asset creation. You need to think of earning links as just a by-product of good content and marketing and not focus so much on it as something to do for "link building".

Acquired Backlinks

It's difficult to compete in SEO if you don't start out with a few link acquisition tactics. It's hard to just depend on earned links, you need to go out sometimes to get others to link to you.

Examples of link acquisition tactics:

1. Guest Posting
2. Submitting to Relevant Local / Industry-Specific Directories
3. Finding Resource Pages on Websites to submit to
4. Paid Directories
5. Paid Links (Risky if not done right)
6. Do-Follow Blog Commenting
7. Researching Competitor Backlinks & acquiring similar links 
8. Sponsor an event/conference/talk knowing fully well that there is a link to be had

The process of link acquisition is getting harder and tougher to scale with Google being more strict about the quality of links required and going to the extent of penalizing sites for acquiring links in mass using spammy tactics. Ideally, your link building strategy should be a combination of some acquisition tactics (done in moderation) and more importantly about creating high quality assets on your site that can earn you some links.
