Backlinks: why links from other sites still matter, and how to earn good ones

A backlink is a link from another website to yours. Search engines treat relevant links from trusted sites as votes of confidence, so they help pages rank, and they help AI assistants recognise your brand. Quality beats quantity: one link from a respected local news site or industry body is worth more than hundreds from spammy directories.

The ₹5,000 link package

A Kollam cake shop bought “500 high-DA backlinks” for ₹5,000. Rankings didn’t move, and some fell.

The links came from irrelevant blogs and foreign directories, the kind Google ignores or treats as spam.

Instead, they got featured in a local food blog, a Kollam news site covered their Onam cake drive, and the city’s wedding planners linked to them. Six links, all relevant, and the shop reached the local pack for “custom cakes kollam”.

Illustrative example based on a common pattern in Kerala e-commerce accounts. Numbers rounded.

What a backlink is

Links help search engines discover pages and judge how trusted and relevant they are. The linking site’s relevance, quality and real traffic matter more than any third-party score.

Links that are bought, swapped in bulk or placed on spam sites can break Google’s spam policies. Paid or sponsored links should carry rel="sponsored".

Link value ≈ relevance of the linking site × its trust and real traffic × where the link sits

How experienced marketers use Backlink

  1. 1. Local businesses

    Local links (news, events, associations, partners) support Google Business Profile rankings.

  2. 2. Guides and tools

    Useful tools and original data (like a Kerala ad benchmark) attract links naturally.

  3. 3. Competitor research

    See who links to competitors and why (SOP 090).

What good looks like

Business typeStarting ruleWhy
Local service business10–30 quality linksOften enough to compete locally.
Link growthSteady, not sudden spikesSpikes from paid links look unnatural.
Anchor textMostly brand and natural phrasesExact-match anchors in bulk are a red flag.

When the number lies

Domain Authority scores
DA, DR and similar scores are third-party estimates, not Google metrics.
Link counts
Thousands of low-quality links can be worth less than one strong one.

Mistakes to avoid

  • Buying link packages

    Wasted money and possible spam penalties.

  • Only linking to the homepage

    Important service pages get no authority.

  • Ignoring unlinked mentions

    Easy links missed; ask sites that mention you to add a link.
