Building quality links for your website is one of the most important activities of SEO. It is the process that involves working with other websites to use links in appropriate places (that are relevant to your business) to bring in traffic for your website.
HubSpot's Link Grader tool lets you know of your own inbound links and also those of your competitors.
In the Reports tab, select Page Performance from the drop-down menu as shown in the following screenshot:
Click on Links to the right-hand side of your browser:
Select a competitor from the drop-down list and see the number of inbound links to your competitor's website. You can prepare a list and target the same websites to build quality inbound links for your website.
With the Link Grader tool, you can check the inbound links for any domain by clicking on the Find links for any domain option as shown in the following screenshot:
Enter the domain name in the Domain textbox and click on Find as shown in the following screenshot:
Now you will be able to see the websites linking back to the domain you just entered. Not all the inbound links are good. HubSpot also helps you with the authority rank to determine the quality of the inbound link. The authority rank is based on the online reputation of that website specifically. Make sure you target the websites with a decent authority rank and start building inbound links.
