Infographics are the most popular visual asset to generate backlinks. If you're not familiar with them, it's a good idea to try them out.
You can simply create a list with customers, business partners or other trusted websites and then include a link back to your website in the testimonial. Google reviews and referrals are great places to start. This is especially important if you are a new business.
The purpose of 301 link building is to find and replace irrelevant 301 redirects. It works because site owners don’t want visitors to “dead” pages.
It's also a great way to obtain backlinks. Old content may have backlinks already, which can be great! Check out the content you've created in order to build backlinks. Create and update relevant information, and make it better than the one you have.
