An internal link connects one page on your site to another page on your site. A backlink connects a page on someone else’s site to yours. They’re often discussed separately, but the strongest SEO strategies use them together.
What internal links do
- Help search engines discover and understand the structure of your site
- Distribute authority from your strongest pages to others that need it
- Help visitors find related content, improving engagement
What backlinks do
Backlinks bring external authority and trust signals into your site from the outside — something no amount of internal linking can substitute for, since it depends on other sites vouching for you.
How they work together
A common, effective pattern: earn a backlink to one strong, link-worthy page (a guide, a tool, an original study), then use internal links from that page to guide both visitors and search engines toward your other important pages — spreading the incoming authority across your site instead of leaving it stranded on one page.
This is exactly why we point every category in our Free Backlink Sites List back to a specific, relevant page rather than just your homepage.
