What Are Link Building Sites?

When we talk about SEO link-building sites, we're referring to platforms that allow website owners, bloggers, and businesses to create inbound links pointing to their websites. These can be in the form of forum profiles, directory submissions, article publishing, or even social shares.

Types of Link Building Sites

Profile Sites – These allow you to create a user profile with your site's link, such as:

• About.me

• Crunchbase

• Forum profiles

Web 2.0 Sites – Platforms where you can publish blog-style content with backlinks:

• Medium

• WordPress.com

Directory Sites – Business directories where you can list your site:

Importance of Authority

Not all backlinks are created equal—search engines look at Domain Authority (DA) and Page Authority (PA) to evaluate link quality. High DA backlinks often have a stronger positive impact compared to low-quality or spammy ones.

Free vs Paid Sites

Free Sites:

• Ideal for beginners

• Low budget friendly

• Wide coverage available

• Require more effort in selection and optimization

Paid Sites:
