How do Backlinks works to increase site visibility and ranking

How backlinks help a website

Among several elements of SEO, a backlink is one of them that helps to grow your online business by giving a boost to your website ranking.

Backlink works in a simple way, let me help you to explain how it works.

For example, John is a blogger who writes about athletics. During his writing, he also shares his perspective about athletics

Another blogger, Rick who also writes interesting details and describes a blog about athletics. Whenever Rick shares any opinion about athletics he mentions the link of John’s post to make it authentic as John is a popular blogger and writes a detailed post about athletics.

Now, John has got a backlink from Rick’s blog, and ultimately it will help John’s website to increase ranking and visibility by Search Engines.

Similarly, some other bloggers, who blog about athletics will give a backlink to Rick’s post, and then his website’s ranking will increase.

Which type of backlink is best for your website

Which type of backlink is best

Basically, there are two types of backlinks No-Follow and Do-Follow. The combination of both should be best for any website. However, Search Engines like Google will only take Do-Follow links as a ranking signal.

But it does not mean that the No-Follow link is trash. Creating a No-Follow link will increase your traffic and whenever more people will remain engaged in your website, Search Engine will consider your blog as valuable and noteworthy and ultimately will increase your site’s ranking and visibility.

Make sure to create both types of a backlink to maintain a balance between your No-Follow or Do-Follow backlinks. Try to avoid black hat techniques for creating Backlink because it will severely affect your online business. One of the popular methods to create a Do-Follow backlink is Guest Posting.

Try to make connections with other bloggers and approach them to post your article on their website by giving a Do-Follow backlink.
