Best Backlink Checker Tools
Written by Ratnesh

In the world of search engine optimization (SEO), using “backlinks” to rank higher on search engine pages is one of the most popular strategies. In fact, the number one result in search engines has an average of 35,000 backlinks!

If you find that your competition is consistently ranking higher in search results, they’re probably utilizing backlinks in a much more efficient way than you are currently.

Even if you’re not an SEO expert, you realize the importance of backlinks. But with the plethora of information available regarding backlink tools, it can be quite overwhelming to choose one.

So, what are backlinks?

In simple words, a backlink is a link that connects users from another website to your website. Social media posts, content on other sites, and web directories are all responsible for bringing organic traffic to your site.

Quantity vs. Quality

There’s an ongoing debate about what matters more: the quality or the quantity of backlinks.

Here’s the thing: A number of sites are dying to add backlinks as it improves their rankings as well. In the eyes of Google, backlinks on these low-quality sites generate low-quality backlinks, which may have the opposite effect and hurt your ranking.

So where do you draw the line and start working on high-quality backlinks?

Brian Dean, the founder of Backlinko and a leading expert in the SEO industry stated:

“I started my first blog way back in 2010. Back then, spammy black hat link building was all the rage. These black hat links worked okay until Google unleashed its Penguin update. This update wiped out 98% of my Google traffic literally overnight. That’s when I decided to go all in on white hat SEO.”

So with Google’s 2012 Penguin update, there’s a high chance that going down the path of generating thousands of low-quality backlinks to your site is a sure¬-shot way of getting blacklisted.

Again, if you only generate a few backlinks from high authority sites, it still won’t budge your ranking as much.

Developing an SEO strategy requires paying close attention to both of these factors instead of just one.

Why you need backlink checker tools:

No matter which point of the distribution curve you’re going to lean toward, you won’t get anywhere without analyzing data.

So, in this post we’re going to discuss some of the tools you can use to understand where you’re getting all the traffic from.

So the best way forward is to carefully analyze your needs and the options you have before making a decision on which backlink tool is going to work for you.
