Backlinks are the chief stimuli for google ranking. Attaining them is hard; but once you start getting them, organic traffic skyrockets. A recent study by Ahrefs suggests that backlinks should be gathered from pages with:
- Multiple referring domains

Link building requires a truckload of effort. Here are the steps involved in the process:
- Prospecting
- Vetting
- Find e-mails
- Verifying emails
- Sending e-mails and following up
There’s no point pretending that you can do it without tools. And you don’t need too many, only these will do. So, here are Top Link building tools you can use to build your SEO strategy.

To automate the whole process, you can add the Zapier integration to combine NeverBounce with Google Sheets. Then, it will automatically tell you if the e-mail you’ve got, is right or not.
Note: You can automate half of your link-building campaign by connecting Google Sheets and NeverBounce. If you've already added the hunter.io extension, use Zapier filters to trigger the automation when you need it. This way, you only need to find and vet link prospects, and the next three steps will happen on their own.
