SEO
Backlinks
Links from other sites. Google's trust signal.
// What it is
Other websites point at yours. Google reads it as a vote: someone trusts you enough to link to you from their own content.
// Why your business should care
Still one of the strongest ranking factors. Without them, your page won't climb past page 10 in competitive niches.
// Common myth
"We need 1000 backlinks." Ten links from serious sites beat 10,000 spam comments from pharma blogs.
Verdict:
Quality is everything. Buying is risky. Earning is slow. Long-term, only the second works.
