There are several ways to get high-quality backlinks to your website.
One of the most obvious and popular ways is through guest posting, which is beneficial to both the guest poster and the blog owner who publishes the article. The key to guest posting is finding industry-relevant and reputable online magazines and blogs, which may accept guest posts linking back to the authors' websites. Depending on the level of readership and the amount of high-quality traffic leading to your website, you can find guest posting to be a rewarding source for backlinking.
Apart from guest posting, there is another effective method for getting reliable backlinks.
The first step is to look for old or outdated websites in your industry that have changed names, shut down, or moved to a new URL.
The next step is to find websites that still link to those obsolete sources, making note of any broken or outdated links that could benefit from updates.
The third and final step is to reach out to all of those websites with a bad link and suggest that they replace one with a link to your website. The best way to do this is to send out a friendly email that comes across as helpful rather than a simple attempt to get a link.
If you seem eager to help other websites by notifying them of bad links, they're much more likely to link to you in return.
