Off-Page SEO & Backlinks

While On-Page SEO optimizes your own code, Off-Page SEO focuses on building your website's trust, reputation, and authority across the web.

What is a Backlink?

A backlink (or inbound link) is a hyperlink on another website that points to your web page.

Website A (TechCrunch) -  -  -  - >  [ Hyperlink ] -  -  -  - >  Website B (Your Site)

Google views backlinks as votes of confidence. If high-authority sites link to your content, search engines assume your content is valuable and rank it higher.

Domain Authority & Link Quality

Not all backlinks are equal!

High-Quality Backlink: A link from an authoritative, trusted site in your industry (e.g. .edu university site, major tech publication, established blog).
Spam Backlink: Low-quality links from link farms, paid link networks, or irrelevant spam comments. These can trigger Google manual penalty flags!

🟣 Important

> Nofollow vs. Dofollow Links: - rel="dofollow": Passes link equity ("SEO juice") to the target site. - rel="nofollow": Tells search engines not to endorse the linked page (used in forum comments and paid ads).
