Backlinks are the most misunderstood concept in SEO. The word itself sounds technical and intimidating. You've probably heard they're important for ranking on Google, but the advice you find online is either impossibly vague ("just get quality links") or terrifyingly complex (domain authority scores, link equity distribution, toxic link penalties).

Here's the truth for micro-businesses: Backlinks are simply votes from other websites. When another site links to yours, they're telling Google "this business is worth paying attention to." The quality of those votes matters far more than the quantity. One link from a respected local business directory is worth more than 100 links from random spam sites.

The problem? Most small business owners have no idea which links they currently have, whether those links are helping or hurting them, or what "quality" even means in practical terms.

This guide cuts through the jargon. You'll check your current backlink status in 20 minutes, understand the simple difference between helpful and harmful links, and create a basic quality standard to guide any future link-building work. No expensive tools required. No technical expertise needed.

In This Guide:


Quick Start: Check Your Link Status (20 Minutes)

This quick process will show you exactly which websites are currently linking to yours (if any) and help you establish a simple quality benchmark.

This builds on understanding your internal link flow — now we're looking at external votes pointing to your site.

Step 1: Define Your Target URL

Write down your full domain name exactly as it appears in the browser (including whether it uses www or not). Most tools will check both versions, but being precise helps.

Example: `www.yourbusiness.co.uk` or `yourbusiness.co.uk`

Step 2: Choose a Free Backlink Checker Tool

For your first check, use one of these free options:

  • Ahrefs Backlink Checker (ahrefs.com/backlink-checker) — Allows 10 free checks per day, shows Domain Rating (DR)
  • Moz Link Explorer (moz.com/link-explorer) — Free account shows limited data, displays Domain Authority (DA)
  • Google Search Console — If you've already set this up, go to Links > External Links (this will be your long-term monitoring tool)

For this initial audit, Ahrefs or Moz will give you the quickest snapshot. You'll set up Search Console properly in the next Blueprint step.

Step 3: Input Your Domain and Run the Check

Enter your domain into your chosen tool and run the analysis. The free versions will show:

  • Total backlinks (how many links point to your site)
  • Referring domains (how many unique websites link to you — this matters more than total links)
  • Top backlinks (usually 5-10 examples)
  • Domain Rating/Authority (a score indicating the "voting power" of linking sites)

Example output from a free backlink checker, highlighting the Domain Rating (DR) metric.

Step 4: Review the Reported Backlinks

Look at the top 3-5 backlinks shown. For each one, ask three simple questions:

  1. Is this a real business or organisation? (Not a random spam site)
  2. Is it relevant to my industry or location? (A local directory or related business)
  3. Does the linking page look legitimate? (Real content, not just lists of random links)

Write down the ones that pass all three tests. These are your "good" links.

If you see links from sites you don't recognise with names like "best-seo-links-2019.info" or pages filled with unrelated link lists, those are low-quality links. Don't panic — we'll address this in the Complete Guide.

Step 5: Draft Your 3-Point Link Quality Standard

Based on what you've just seen, write down your personal definition of a "good link source" using these three criteria:

My Link Quality Standard:

  1. Relevance: The linking site should be related to my industry, location, or customer base
  2. Trust: The site should look professional and legitimate (real business, established organisation, quality content)
  3. Context: The link should appear in actual content, not just a link directory or footer list

Save this somewhere accessible (a Google Doc, your business notebook, or your project management tool). This becomes your filter for evaluating future link opportunities.

Next Step: Set up Google Search Console to monitor your backlinks (and other technical issues) automatically moving forward.


Exit Point: If you just needed to understand your current link status and establish a quality benchmark, you're done. The Complete Guide below explains why these links matter, how Google uses them, and simple ways to start building your first quality links ethically.


Complete Step-by-Step Guide to Backlink Value

Now that you've checked your current status, let's understand exactly how backlinks work, why quality matters more than quantity, and how to start building valuable links without expensive outreach campaigns or dodgy tactics.

Step 1: Backlinks Are Votes — Understanding Domain Authority

When Google's algorithm evaluates your website, it looks at hundreds of factors. Backlinks are one of the most important because they represent external validation. Think of them as references on a CV — anyone can claim they're good at their job, but references from respected sources carry weight.

Domain Rating (DR) and Domain Authority (DA) are third-party metrics (created by Ahrefs and Moz respectively) that estimate the "voting power" of a website based on the quality and quantity of links pointing to it. These scores run from 0-100.

What the scores mean in practice:

  • DR/DA 0-20: New sites, personal blogs, or low-quality sites (weak vote)
  • DR/DA 20-40: Established small businesses, niche blogs, local organisations (decent vote)
  • DR/DA 40-60: Regional publications, industry associations, established media (strong vote)
  • DR/DA 60+: National newspapers, government sites, major brands (very strong vote)

For micro-businesses, the practical rule is simple: One link from a DR/DA 30+ site that's relevant to your industry is worth more than 50 links from DR/DA 5 spam sites.

Good links come from relevant, trusted sources; bad links come from spammy, irrelevant sites. Focus on the quality of the surrounding web ecosystem.

Google doesn't use DR/DA directly (those are third-party metrics), but it evaluates similar signals about trust and authority. The scores are useful shorthand for "is this a legitimate site worth getting a link from?"

Step 2: The Two Essential Types — Do-Follow vs No-Follow

Not all links pass the same "voting power." There are two technical types:

Do-Follow Links (the default): These pass "link equity" — they tell Google "I vouch for this site, count this as a vote." This is what you want for SEO benefit.

No-Follow Links: These include a small piece of code (`rel="nofollow"`) that tells Google "don't count this as a vote." They were originally created for user-generated content (blog comments, forum posts) to prevent spam.

Do you need to worry about this distinction? Not really. Here's why:

  • Most legitimate links are do-follow by default
  • No-follow links still send traffic and build brand awareness
  • Google has softened its stance — no-follow is now treated as a "hint" rather than an absolute directive
  • A natural link profile includes both types

The practical takeaway: Focus on getting links from quality sources. Don't reject a link opportunity just because it's no-follow — traffic and visibility matter too. But understand that do-follow links from relevant sites are the primary SEO benefit you're after.

Step 3: Identify a Toxic Link — A Quick Guide to What to Avoid

"Toxic links" are backlinks that could potentially harm your rankings. Google's algorithm has become very good at simply ignoring low-quality links, but in extreme cases (thousands of spam links), they can trigger a manual review or penalty.

Red flags for toxic links:

  1. The linking site is clearly spam — Pages filled with unrelated links, no real content, broken design, or suspicious domain names (e.g., "get-backlinks-fast-2015.biz")
  2. The link appears in a site-wide footer or sidebar — If your link appears on every page of a random website you didn't request, it's likely part of a link scheme
  3. The linking page is in a completely unrelated language or industry — A Russian gambling site linking to your UK plumbing business is not a natural vote
  4. You paid for the link explicitly for SEO — Google's guidelines prohibit buying links that pass PageRank (though sponsored content with proper disclosure is fine)
  5. The anchor text is over-optimised — If dozens of links all use the exact same keyword phrase (e.g., "best plumber in Manchester"), it looks manipulative

What to do if you find toxic links:

For most small businesses, the answer is: nothing. Google is very good at ignoring low-quality links automatically. You'll waste more time worrying about them than they'll ever harm you.

Only consider a disavow file if:

  • You've received a manual action penalty in Search Console
  • You have hundreds or thousands of obvious spam links (from a previous SEO agency's bad practices)
  • You're actively being targeted by a competitor with negative SEO (extremely rare)

The disavow process is covered in our guide on fixing crawl errors in Search Console — but for 95% of micro-businesses, it's unnecessary.

Backlinks only matter if your technical foundation is sound. Not sure you've covered the prerequisites like speed and mobile performance? NetNav's technical audit checks these foundational areas in 60 seconds, ensuring your site is ready to receive those valuable votes.

Step 4: Setting Your Link Quality Standard — Relevance, Trust, Context

You drafted a basic quality standard in the Quick Start. Now let's refine it with three specific criteria you can apply to any link opportunity:

1. Relevance

The linking site should connect to your business in at least one of these ways:

  • Industry relevance: A trade association, industry blog, or complementary business
  • Geographic relevance: A local directory, chamber of commerce, or regional publication
  • Audience relevance: A site your ideal customers actually visit

Example: A link from your local council's business directory is geographically relevant. A link from a national trade body is industry relevant. Both are valuable.

2. Trust

The linking site should demonstrate legitimacy:

  • Professional design and functioning website (not broken, outdated, or spam-filled)
  • Real organisation or business (verifiable contact details, about page, real people)
  • Quality content (actual articles, information, or services — not just link lists)
  • Secure connection (HTTPS, not HTTP)

You don't need to run a full audit — a 30-second "does this look like a real business?" check is sufficient.

3. Context

The link should appear naturally within content:

  • Editorial links (mentioned in an article, blog post, or resource guide) are best
  • Directory listings (with your full business information) are good for Local SEO strategy
  • Footer or sidebar links (site-wide) are lower value but acceptable if from a legitimate partner
  • Link farms or "resources" pages (just lists of random links) are worthless

The surrounding text matters too — this is where anchor text and relevance come into play. A link in a sentence like "We worked with [Your Business] on this project" is more valuable than a link in a list with no context.

Identifying toxic links or dead links is a time-consuming manual process. This is one of the key safety checks NetNav runs automatically across your whole site, flagging high-risk links so you don't accidentally get penalised by Google.

Step 5: Simple Actionable Ways to Get Your First Good Links

You don't need an expensive link-building campaign or outreach agency. For micro-businesses, the most valuable links come from sources you already have access to:

1. Local Business Directories

Start with free, high-authority directories:

  • Google Business Profile (essential — covered in Get Your Business on Google Maps)
  • Bing Places for Business
  • Your local council's business directory
  • Chamber of Commerce (if you're a member)
  • Industry-specific directories (e.g., Checkatrade for tradespeople, Trustpilot for reviews)

These provide do-follow links, improve your Local SEO strategy, and ensure consistent business details across the web.

2. Existing Business Relationships

You already have connections that can provide quality links:

  • Suppliers or partners — Ask if they feature clients on their website
  • Clients you've worked with — Case studies or testimonials often include links
  • Trade associations or memberships — Most have member directories
  • Local networking groups — BNI, FSB, or informal business groups often have websites

The ask is simple: "We're working on our online presence — would you be able to link to our website from your [partners/clients/members] page?"

3. Local Media and Community Sites

  • Local news sites — Offer to comment on industry stories or contribute expertise
  • Community websites — Sponsor a local event or charity (legitimate sponsorship, not just link buying)
  • Local bloggers — If there's a local lifestyle or business blogger, offer to be featured

4. Create Link-Worthy Content

If you're considering whether you should blog, one benefit is that useful resources naturally attract links:

  • Local guides ("The Complete Guide to [Your Service] in [Your Town]")
  • Industry data or case studies (original research or results)
  • Free tools or templates (calculators, checklists, downloadable resources)

This is a longer-term strategy, but one genuinely useful piece of content can earn links for years.

What NOT to do:

  • ❌ Buy links from "SEO services" offering packages of 100 links for £50
  • ❌ Participate in link exchanges ("I'll link to you if you link to me")
  • ❌ Comment spam on blogs just to get a link in your signature
  • ❌ Submit to hundreds of low-quality directories

These tactics either don't work or actively risk penalties.

Step 6: What to Do with Bad Links — Disavow Only If Necessary

If your backlink check revealed some questionable links, here's the decision tree:

Scenario 1: A few low-quality links (under 10)

Action: Ignore them. Google will ignore them too. Focus your energy on building good links.

Scenario 2: Dozens of spam links you didn't request

Action: Monitor in Search Console. If you're not seeing any ranking drops or manual action warnings, still ignore them. Google's algorithm handles this automatically.

Scenario 3: Hundreds of obvious spam links (from a previous bad SEO agency)

Action: Consider a disavow file. This tells Google to ignore specific domains when evaluating your site. The process is covered in disavow toxic links, but only do this if you have clear evidence of harm.

Scenario 4: You've received a "Manual Action" penalty in Search Console

Action: Immediate disavow required. Follow Google's reconsideration process, document your cleanup efforts, and submit a disavow file with your reconsideration request.

For 90% of small businesses reading this, Scenario 1 applies. Don't let fear of "bad links" paralyse you — Google is sophisticated enough to ignore them.

Where to find the 'Links' report within Google Search Console (our recommended primary monitor).

Next Step: Set up Google Search Console to monitor your backlinks automatically and catch any issues before they become problems.
