What Are Backlinks?

Backlinks are links from other websites to yours. Why they matter for rankings, what good links look like, and what to avoid.

Mantras Marketing

A backlink is a link from another website to yours. Search engines treat links from credible, relevant sites as signs of trust and authority, so a healthy set of backlinks can help your pages rank higher. Quality and relevance matter far more than raw quantity, and a small number of strong links routinely outperforms a large number of weak ones.

When two businesses have similarly built pages and similar reviews, the one with stronger, more relevant backlinks often ranks higher, because search engines use links as one signal of which sources other sites and organizations consider worth referencing. Links also send visitors directly from other websites, independent of search rankings entirely. Authority earned through backlinks tends to support the whole site, not just the specific page that received the link, which is why a single strong link can have a broader effect than it first appears.

A good backlink comes from a relevant, credible site, sits within genuinely useful content rather than a random list, and uses natural, descriptive wording rather than an obviously commercial phrase. For contractors, strong sources include local organizations, suppliers, manufacturers whose products you install, and helpful local resources that already have their own credibility built up over time.

Anchor Text

Anchor text is the clickable wording of a link. Natural anchor text describes the destination, such as “emergency plumbing services in Denver,” rather than repeating an exact keyword phrase on every link, which can look manipulative to search engines when it happens at scale across many different linking sites.

What to Avoid

Avoid buying links outright, joining reciprocal link networks or link farms, and mass outreach campaigns that place links on low-quality or unrelated sites purely for SEO purposes. These tactics can lead to search engine penalties that are slow and difficult to reverse. A handful of relevant, earned links from credible sources consistently outperforms a large volume of poor ones accumulated quickly.

  • Paid links that are not disclosed as advertising
  • Directory submissions to low-quality, irrelevant sites purely for a link
  • Reciprocal link exchanges arranged solely to trade links
  • Guest posts placed only for a link, on sites unrelated to home services
  • Automated or bulk link-building software

Sponsor or join local trade groups, chambers of commerce, and community organizations that list members with a link. Ask suppliers and manufacturers to list you as a certified installer, which often comes with a link from their dealer locator page. Publish guides genuinely worth referencing, such as a detailed maintenance checklist a homeowner would actually bookmark. Claim mentions of your business that do not yet link to you by reaching out and asking for a link to be added to the existing mention. Read about our approach to link building.

A backlink and a citation are not the same thing, though they can overlap. A citation is defined by containing your business name, address, and phone number, with or without a link. A backlink is defined by containing a link, whether or not it includes your NAP data. A directory listing that includes both your NAP and a working link to your site functions as each at once. See what local citations are.

Relevance to your trade and location, the linking site’s own credibility, and whether the link sits within genuine content rather than a footer or sidebar list are more informative than any single automated score. A link from a regional plumbing supply company’s installer page is more valuable to a plumber than a link from an unrelated national directory with no local connection at all.

Backlinks work best alongside, not instead of, a complete Google Business Profile, consistent citations, and a well-built website. A strong link profile pointing to a thin, incomplete site rarely produces the same result as the same links pointing to a site that fully backs up the trust those links are signaling.

Content Worth Linking To

Earning links usually starts with having something genuinely worth linking to in the first place, rather than outreach alone. For contractors, this often means original, specific guides that a reasonable person would actually bookmark or reference.

  • A detailed seasonal maintenance checklist specific to your trade
  • An honest explanation of what affects pricing for a common job
  • A clear breakdown of a process customers rarely see explained plainly
  • Original photos or documentation of real completed work

Effective outreach for a contractor tends to be modest in scale and highly targeted: a short, genuine message to a supplier, association, or local organization explaining a real, existing relationship, rather than a mass email sent to hundreds of unrelated sites hoping a few respond. This approach produces fewer links overall but a much higher share of them are relevant and durable.

Search engines specifically watch for patterns such as sudden bursts of similar-looking links, links exchanged in bulk between unrelated sites, or paid placements disguised as editorial content. A contractor approached by a vendor promising a large, fast number of backlinks for a flat fee should treat that offer with caution, since it frequently describes exactly the kind of scheme search engines penalize.

Backlinks come from other websites, while internal links connect pages within your own site, such as a blog post linking to a relevant service page. Both matter, but they serve different purposes: internal links help visitors and search engines navigate your own content, while backlinks signal outside trust and authority that no amount of internal linking can substitute for.

Unlike a paid ad that can scale spend up immediately, earning genuine backlinks is inherently gradual, since it depends on real relationships, genuinely useful content, and other sites choosing to link on their own terms. A realistic plan sets modest, steady monthly goals rather than expecting a large batch of new links in a short window, which is itself a signal search engines tend to view with suspicion.

Plumbing, HVAC, and solar each have their own trade associations, certification bodies, and regional supplier networks, many of which maintain member or installer directories online. These niche communities tend to be both easier to earn a link from, since membership is often the only requirement, and more relevant than a generic business directory with no connection to the trade.

Before pursuing new links, review what already points to your site. Tools built for this purpose can surface existing backlinks, showing which are strong and relevant, which are weak or irrelevant, and whether any past marketing effort left behind links that no longer serve the business or, in rare cases, could be actively working against it.

Backlinks contribute to the prominence factor in local ranking alongside reviews and citations, which means link-building efforts and broader local SEO work reinforce each other rather than operating as separate tracks. A relevant local link often comes bundled with a citation and sometimes even a review, making relationship-based outreach one of the more efficient uses of time for a contractor.

A contractor evaluating an outside vendor for link building should ask specifically where links will come from, whether the sites are relevant to home services, and whether the pace of new links will be gradual and natural. Vague answers, or a refusal to disclose specific sources in advance, are reasonable grounds for caution before committing budget.

Sponsoring a youth sports team, participating in a local charity event, or supporting a school fundraiser can produce a genuine, relevant local link from the organization’s website, alongside real community goodwill that exists independent of any SEO benefit. This kind of link tends to be both easier to earn and more durable than one pursued purely for ranking purposes.

Rather than a single large campaign, many contractors find more success setting aside a small, consistent block of time each month to identify one or two realistic link opportunities, whether that is a supplier not yet listing them, a local organization they could join, or an unlinked mention found through a search of their own business name.

The most durable backlinks come from real relationships and genuinely useful content, not a transaction. Treating link building as a byproduct of being a visible, credible, connected local business tends to produce a steadier, safer result over time than treating it as a service that can simply be bought in bulk from an outside vendor.

A Final Thought on Patience

Backlinks are one of the slower-moving pieces of local SEO to build deliberately, and that is by design; a genuinely earned link profile cannot be rushed without starting to resemble the manipulative patterns search engines actively look for. Steady, modest, relevant progress each month is the realistic, sustainable path for a contractor building authority over years, not weeks.

The strongest backlink profile a contractor can build is often simply a byproduct of being genuinely active in the local community: joining associations, supporting suppliers, and being the kind of business other organizations are glad to mention. Approached this way, link building stops feeling like a separate marketing task and becomes a natural extension of running a well-regarded local business.

A Closing Note on Where to Focus First

A contractor with limited time should focus first on claiming any existing unlinked mentions of the business, then on trade association and supplier listings, since both tend to be the fastest, most reliable, and most relevant sources of a genuine local backlink.

One More Thing Worth Remembering

A single strong, relevant local link earned this month is worth more than a large batch of low-quality links acquired quickly, both for search engine trust and for the durability of the results over the following years.

A Final Encouragement

Every genuine relationship a contractor builds with a supplier, association, or local partner is a potential backlink waiting to be asked for, which means link-building opportunities are often closer at hand than they first appear, already embedded in relationships the business has built simply by operating locally for years.

Links differ in how they are earned and how much trust they carry. Focus on links from real local and industry sources.

Before you build new links, see what you already have. Google Search Console lists sites that link to you under the Links report. It is free, and it shows your top linking pages and sites.

Look for three things: links from relevant sites you already earned, links that look spammy, and pages of yours that attract links. If a strange batch of low-quality links appears, note it. Google says it generally ignores such links, and it recommends the disavow tool only in unusual cases.

A steady stream of relevant links beats a sudden burst. Our link building service follows that principle, and we never buy links.

Do-Follow, No-Follow, and Why the Difference Matters Less Than You Think

Links carry an attribute that tells search engines how to treat them. A standard link passes trust. A link marked nofollow, sponsored, or ugc tells search engines to treat it with caution.

For a contractor, the safest goal is not to hunt for a particular type. It is to earn links that a real person would click, from sites related to your work or area. A mix of link types looks natural, and natural is what matters.

You do not need hundreds of links. A steady program of relevant ones is enough for most local markets.

  • Ask suppliers and manufacturers to list you as an installer or dealer.
  • Join your local chamber of commerce and trade associations.
  • Sponsor a local team or event, and ask for a link on the sponsor page.
  • Publish a useful local guide that others may cite.
  • Share real projects with local news outlets.

Frequently Asked Questions

Do all backlinks help?

No. Relevant, credible links help, while low-quality, unrelated, or manipulative links can hurt rankings or trigger penalties in more serious cases.

How long do backlinks take to work?

New links are usually discovered by search engines within weeks, but their measurable effect on rankings tends to build over months rather than appear immediately.

Are nofollow links useless?

Not entirely. They can still send referral visitors and contribute to a natural, diverse link profile, though they generally carry less direct ranking weight than followed links do.

Can I remove a bad backlink myself?

You can request removal from the linking site, or in serious cases use a disavow process, though most contractors will never accumulate enough harmful links to need this step.

How many backlinks does a contractor site need?

There is no set number. A smaller number of genuinely relevant, high-quality links tends to outperform a larger number of low-quality ones by a wide margin.

Does social media count as a backlink?

Most social platforms use nofollow links, which carry less direct ranking weight, but they still provide visibility and can lead other sites to discover and link to you.

Should I try to get links as fast as possible?

A sudden, unnatural spike in links can look suspicious to search engines. A steady, gradual pace that reflects genuine outreach and relationships tends to hold up better over time.
