Who else wants to know the best backlink checker tools to analyze your page ranking factors? Are you focusing much on building quality backlinks to move your best keywords to Google top results? If yes, this article is for you where I am going to discuss about best backlink finder tools to analyze your inbound and outbound links.

Whether you agree or not, backlinks are the backbone of any successful site. Although, Google is not giving too much priority to the backlinks in recent days, but still backlinks matter a lot if you are targeting for first page results for your keywords on Google or any other search engine.

How important are your inbound and outgoing links from your websites? In simple terms, the strategy you use for the backlinks (internal or external) on your websites decide your SEO traffic. This is why it is essential to find and analyze backlinks before jumping into increasing organic traffic.

Why backlinks are important?

In simple terms, backlinks are any links that are either pointing to your web pages, or going out from websites. For instance, this is a backlink (also called internal link to one of my blog posts). You may now ask, why backlinks are important?

SEO is the real key to any website success. SEO can make or break a profitable site, it’s that important. If you are starting a blog or started a blog already, you need to optimize your blog posts for the search engines. If you don’t do SEO on your sites, no matter how many posts you write, you won’t receive much traffic from Google. So always make sure to optimize your posts before hitting publish button.

Google depends on different search engine ranking factors to rank different sites and web pages. There are upwards 200 different search ranking factors Google considers and one among them is ‘back links’.

If you give top priority to building high quality backlinks to your websites, your SEO efforts will be more fruitful. Observe any successful blog in your niche, they all have quality backlinks pointing to their web pages. That is the reason why they are ranking high for almost every keyword relating to their niche. That’s what you exactly need to do if you are aiming for top search results on Google, aim for building quality backlinks over quantity.

It’s always better to get a link from PR 5 site than getting 10 backlinks from a PR 2 site. So make sure to optimize your SEO efforts by focusing on building quality external backlinks and don’t use black hat SEO tactics, and you will be fine.

Getting Quality Backlinks to Your Websites

As I said above, it’s about the quality of backlinks that matter most than that of the quantity. It doesn’t matter even if you build thousands of backlinks from poor sites, you won’t get better SERP rankings for your keywords without having quality backlinks.

Then how to get quality backlinks to your sites in 2021?

1. If there’s ONLY one way to boost your SEO of your sites, it is getting links from the top blogs. You can use guest posting strategy to get it done. Read top blogs in your niche and find out what their readers are craving for, then write guest posts according to their needs. You will see a dramatic change in your SERP rankings once the top blogs link to your sites.

Guest blogging is still one of the finest ways to build backlinks. Most people now are aware of the fact that, guest blogging links to false sites (negative sites) can penalize their sites in the search results. So most of the bloggers are now carefully selecting guest posts to publish on their websites.

That’s a great news if you are focusing on getting quality backlinks by writing quality guest posts. All you have to do is to find out the best blogs that are still accepting guest posts, research the best topics for them, and pitch better guest posts to get links from them.

2. What if you are not interested in guest blogging? There’s one smart way to build quality backlinks without guest blogging. Write detailed blog posts on your websites and link to the relevant posts from other blogs in your niche. In other words, start linking to other blogs from where you want to get backlinks.

This doesn’t guarantee you getting backlinks, but if you email them about your stuff and convince them your posts will be useful to their users, they will definitely consider linking to your sites. After all, everyone wants to give their blog readers quality stuff. So focus on writing great content for your blogs first and then start linking to others.

3. Creating infographics is the latest trend and most people are now linking to quality infographics. So come up with a hot topic or trend, invest some money on creating visually appealing infographics and you are done. Try to promote it to reach more people so that your chances of getting links from others to your infographics will increase rapidly.

Although there are hundreds of other ways to build backlinks, the above mentioned ways always work no matter what. Moreover we are not going to cover more details on building backlinks in this post, so without much ado let’s dive into the details of backlinks checker tools for your websites.
