Top 15 Link Building Tools in 2021 to Help You Climb SERPs (+ Reviews)

Ranking your website on Google is the best way to drive traffic to your website, grow your readership, and increase your customer base. The art of doing this is called search engine optimization or SEO.

A primary component of building your authority to improve ranking potential in search engine results pages (SERPs) is earning links from other websites. This common SEO tactic is referred to as link building. 

Prospecting for link building opportunities is an extremely cost effective method for driving traffic. Fortunately, there are some great link building tools out there that can make the process even faster and easier.

Link building tools help you see who is linking to your website, identify what businesses are linking to your competitors' websites, and compile webmaster's contact information to help you build a list of potential link partners.

What Is Link Building?

Link building is an SEO strategy that involves acquiring hyperlinks from other websites and including them in your own website content. A hyperlink (link) is a way for site visitors to go from one page to another on the internet. The goal of link building is to improve search visibility.

Link building strategies include:

• Email outreach
• Content marketing
• Public relations
• Broken link building

A backlink is a link that is created when another website links to a page on your website. Backlinks help to boost your SEO because they send a signal to search engines that your site is high quality and that your content includes helpful information. 

Some other benefits of backlinks include:

• Faster indexing
• Referral traffic
• Organic search ranking improvements

7 Tips for Building the Best Backlinks

Here are seven best practices to help you build the best backlinks for your website.

1. Turn Your Mentions Into Backlinks.

This is an easy way to gain new backlinks for your site since someone already wrote something about your brand.

They may mention your brand on a website, social media, or on another channel, but they have not linked back to your site to provide you with that link equity (aka link juice).

To grab some of these backlinks, start by contacting the webmaster and asking them to convert the mention into a backlink. Usually a simple email will do. In most cases, other brands or blogs should link to your site when they mention you. 

If not, search for mentions with easy-to-use tools like LinkResearchTools.

2. Apply the Broken Link Building Method.

The broken link building method involves searching top websites in your industry or niche to find dead pages. You then recreate the broken content and contact the webmaster to replace that broken link with a link to your new content. 

This method may be time consuming if you don't have the right tools. Try using Ahref's Site Explorer, which provides a broken backlinks report to make searching and compiling broken backlinks easy.

3. Take Advantage of Guest Blogging.

Guest blogging is a highly effective way to reach new readers and to gain more exposure. All you have to do is publish blog articles on other popular websites. In addition to gaining backlinks, you'll also increase your online reputation. 

Search the web to find blogs that accept guest contributors and submit your guest blogging proposal.

4. Write Testimonials.

Offering to write testimonials for brands that you have done business with is a great way to get high quality backlinks.

Select the top tools or brands you work with and get in touch with them to see if they will post a review about your experience with them on their website or blog. 

Brands are usually willing to accept good feedback and share it with others. They will often link back to your website in the author's byline section of their testimonials page. 

5. Consider the Authority of the Linking Page or Site.

A link acts as a vote of confidence in the website being linked to. When you earn a link from an authoritative site, that signals to search engines that your site is a credible resource for the content being linked to. 

Generally speaking, the higher the authority of the referring domain linking to your website, the more value you're getting from that backlink. 

There are two metrics that can help you figure out the authority of a site when you use tools like Ahrefs:

• URL Rating: The strength or authority of a webpage measured on a scale from 0 to 100.
• Domain Rating: The overall authority of a whole website, measured from 0 (lowest authority) to 100 (highest authority). 

If you're using Moz, you will see a similar authority model called domain authority. These proprietary scoring systems are helpful to look at and analyze on an ongoing basis. Ideally, the more quality backlinks you get, the higher you will see your authority scores climb. 

6. Analyze Competing Sites.

Analyze the backlink profiles of competing sites to gain insight into their link building strategies and to find opportunities to replicate their links. 

The idea is to figure out how or why your competitor received a certain link and to determine if it is something you can do as well. 

Some easy links you can replicate include:

• Guest post links
• User generated links
• A link from a resource page

7. Conduct Effective Outreach.

Outreach is an essential link building skill that can help you gain access to the best linking opportunities. You may reach out to brands, influencers, bloggers, and press websites via email or social media to entice them to link to your content. 

The best link building outreach tactic involves reaching out at the right time to increase your success rate. You can set up alerts on Ahrefs to actively monitor the web to find  links to specific competitor content, brand mentions, and when a specific keyword is mentioned. 

Reach out quickly when you are alerted to one of these items to ask if they would consider linking to your similar resource. 

Most, if not all, of these tips require you to use link building or outreach tools to make your link building strategies simple and effective.
