Backlink

A backlink is a link from another website to yours. Links remain one of the strongest ranking signals, but the count matters far less than it once did. One link from a relevant, credible site is worth more than hundreds from directories nobody reads.

What a search engine reads is the pattern: who links, how relevant they are, what the anchor text says, where on the page the link sits, and whether the profile looks earned or assembled. A sudden influx of unrelated links from unrelated countries is a recognizable shape. So is a footer link repeated on every page of a site with the same keyword-rich anchor. Links marked nofollow, sponsored or ugc are treated as hints rather than votes, and that is how any paid placement should be labeled.

Buying links violates Google’s spam policies. The risk is real: it is the most common cause of a manual action against a commercial site.

A link either carries a rel attribute or it does not. A link without one is usually called dofollow, a word the industry uses even though Google does not. Since 2019 Google treats nofollow, sponsored and ugc as hints rather than strict instructions.

A natural profile includes both kinds. Nofollow links from relevant places still bring visitors, mentions and discovery.

Most of this can be done with free tools. Paid tools add coverage and history, which helps on larger sites or in competitive markets.

• Export your current links from the Links report in Google Search Console and from Ahrefs or Semrush, which find links Search Console does not list.
• Sort the linking domains by relevance to your business and market before looking at domain metrics.
• Check the anchor text distribution. Most anchors should be your brand name, your URL or natural phrases.
• Find links pointing to 404 or redirected URLs and recover them with a redirect, or by asking the site owner to update the link.
• List the relationships you already have: clients, suppliers, partners, associations, local press. They are the most natural sources of new links.
• Give each of those audiences something worth linking to, such as a case study a client can reference or a guide a partner can recommend.
• Review new links every month in Ahrefs or Semrush. Consider the disavow tool in Search Console only if you find a manipulative pattern that you or a past provider created.

• Relevance of the linking site to the topic and market of the page it links to.
• Anchor text distribution, with brand and natural anchors as the majority.
• Placement: links inside content carry more weight than footers and sidebars.
• Links pointing to redirected or broken URLs, which can be recovered.
• Sudden spikes of low-quality links that may need investigation.

Generative engines do not publish how they weigh links, but links reach them indirectly. Google’s AI Overviews draw on pages from Google’s index, where links still count. The articles and directories that mention and link to your brand can also be among the sources ChatGPT and Perplexity read when they describe a company, so a mention in a relevant industry publication works as a link for search and as a description of your brand at the same time.

For local SEO, links from local sources such as a neighborhood association, a local news site or a nearby partner business support relevance for that area. Mentions of your name, address and phone without a link, known as citations, help the Business Profile as well.

1. Small business.A few links from clients, suppliers and local organizations usually do more than any campaign. Start with relationships you already have.
2. E-commerce.Product reviews, comparisons and supplier pages are natural link sources. Category pages rarely earn links on their own, so internal linking has to pass authority to them from the pages that do.
3. Multilingual site like ours.We ask each partner to link to the version in its own audience’s language and rely on hreflang and internal links to connect the pair.
4. Local service business.Local directories, chambers of commerce and neighborhood sites are worth more here than national listings, because relevance to the area is what counts.

Whatever the case, the test for each link is the one we apply to our own: would a reader of that page click it? If the answer is yes, the link is probably worth having. If it exists only for search engines, it falls into the pattern Google’s spam policies describe.

• Buying link packages or joining link exchange networks.
• Using the same exact-match keyword anchor everywhere.
• Asking partners for sitewide footer links.
• Chasing domain metrics while ignoring whether the linking site is relevant to your business.

Link building is one part of traditional SEO. For a local business, relevant links from your own area are part of local SEO too.
