This is another free tool of Ahrefs.

There are two main benefits of using this tool.

  • You can check the keyword difficulty level.

Whenever you are writing a blog post, make sure that you enter the target keyword for the blog post in this tool to check how many backlinks and referring domains you need to be able to rank in Google and

also determine the keyword difficulty value and decide whether you can rank in Google top10 for that keyword.

  • You can target keywords which attract links.

Many premium SEO tools have different keyword difficulty Metrics and when it comes to Ahrefs,

it will check the keyword difficulty and give you a score between 0-100 and an estimated number of backlinks you need to be able to rank in Google for the keyword by analysing backlinks of the top 10 ranking pages in Google.

For examples let’s consider a keyword,

Google ranking factors in this tool.

This keyword is extremely difficult to rank and it says that you need backlinks from more than 600 different websites to rank in Google top positions.

You cannot get 600 websites to link to your article just by doing manual link building so, it is a perfect example of a link magnet which naturally attracts links.

 if you create amazing content around this keyword which is much better than other pages ranking for this keyword in Google,

you can attract many backlinks both naturally over a period of time and by build backlinks manually through guest posting, broken link building and other link building strategies.

Using this tool you can focus on creating content which targets both low competition keywords and also on keywords and

content which can get you backlinks naturally because they are link magnets and people are also linking to this type of content naturally.

The only drawback of using this tool is that you will have to manually search the keywords that you find through keyword tools to find keyword difficulty for free.

  1. Canva.

free link building tools

Canva is a freemium graphic design tool that you can use to create amazing graphic design posts like infographics and other types of posts like social media posts through simple drag and drop feature.

You can use canva to create infographic and other beautiful graphics and custom images for your website and you can use those images and visuals to get backlinks from other authority websites through Guestographic method.

There is also a premium version of this tool which costs around 10$/month and you can read my ultimate review of the Canva here.

This is one of the easiest ways to get backlinks from other authority websites in the long-term because creating,

adding high quality custom images on your website is a great way to get links when others find your visuals interesting, they can use you images and cite a link to your site as a source to avoid copyright infringement.

It is quite time consuming but definitely worth it.

11. Disavow.

Disavowing the backlinks is a common practice that all bloggers and webmasters use to protect the website from getting a manual action penalty from Google.

Using this tool you can create a file of all the links that you want to disavow and disown from your website so that you can either remove the manual action penalty or protect your website from letting anything like that happen in future.

After you create this file you can upload it in Google search console and let Google know that you don’t want these links to be taken into consideration for your website.

Important Note:

Disavowing backlinks is one of the tough tasks for many bloggers because there is always a risk of losing quality backlinks in the process but

it should not always be your go to solution if you found lots of spammy backlinks pointing to your website.

John Muller who is the senior web analyst of Google recently said that Google will ignore a lot of backlinks pointing instead of

penalising sites so he does not advise people to disavow backlinks which are appearing spammy to the Webmaster.

Google’s algorithms have become more smarter and better at understanding the links.

So I would not recommend you to disavow spammy backlinks from your link profile.

It doesn’t make a huge difference in your rankings and traffic overall and in most cases you will not get a panda penalty from Google as well.

So don’t worry and stress about spammy backlinks on your link profile, it is completely normal and natural.

  1. HARO.

HARO is an acronym for help a reporter out. We all know that building backlinks from highly authoritative media websites is one of the best ways to Boost Your rankings and get more traffic from Google.

Media Websites like Forbes,entrepreneur, mashable, Business Insider, New York Times, etc.

But it is quite hard to get backlinks from those websites.

Thankfully we have this freemium tool/service called HARO.

When you get those emails to your inbox, if you have the right information and share it within the deadline time to the email,

you can get high quality backlinks from highly authoritative media websites like Business Insider and mashable, etc.

  1. Google search operators.

We all try creating content, doing SEO and link building only to rank high on Google for more traffic at the end of the day, isn’t it?

So if it is all about Google, why not use Google itself to rank higher in Google.

Yes, you read that right.

Google search engine is also a great tool to find and build amazing high quality backlink opportunities for your website.

For example if you have a website related to Digital marketing like I do and if you want to get backlinks to that website, you can find link building opportunities from various ways like,

  • Guest posts.
  • Resource pages.
  • Link roundups.

For example in my case I have a digital marketing blog and if I want to write a guest post on other websites related to my industry.

I search something like this in Google to find relevant websites that accept guest posts on their website related to the Digital marketing niche.

Digital marketing”write for us”.

free link building tools

Digital marketing”contribute”.

Digital marketing”submit a post”.

Now Google will only show all the results which are related to the digital marketing industry and have a page on the website that accepts guest posts like write for us, or contribute sections.

I can select any one among those depending upon the domain authority and their backlinks profile and send a guest pitch and subsequently submit a guest post.

If I want to find resource pages then I would use these search operators,

Digital marketing”resources”

Digital marketing intitle:”resources”

Lastly,

If I want to find link roundups then I would search,

Digital marketing”link roundups”.

Using these search operators of Google you can find amazing link building opportunities for your website for absolutely free of cost.

These search operators are largely effective to find guest posting opportunities.
