A good backlink comes from a real, relevant website that Google already trusts. A bad one comes from a site that exists purely to sell links. The difference matters because bad links can actively damage your rankings. That’s why “50 backlinks this month” can be brilliant, useless, or a complete bin fire depending on where those links came from.
Why backlinks still matter in 2026
Backlinks still matter because Google uses links as one way to judge trust, authority and reputation. Not the only way. Not a magic button. But still important.
Think of a backlink as someone else vouching for your website. If a respected local newspaper, trade association or industry publication links to you, that tells Google your business exists outside your own website. You’re not just shouting into the void.
The problem is that the SEO industry has abused backlinks for years. Some agencies still sell “high DA link packages” like they’re bags of gravel. Cheap, heavy and mostly useless.
Google’s systems have become much better at spotting nonsense. A backlink from a relevant, trusted site can help. A backlink from a fake blog stuffed with casino, crypto and plumber links probably won’t. Worse, if your backlink profile looks deliberately manipulated, it can put you at risk.
So yes, backlinks matter. But only the right ones.
What Google is actually looking for
Google is not sitting there counting links like a bored nightclub bouncer with a clicker. It is trying to understand whether links make sense.
The big three are relevance, authority and editorial context.
Relevance means the linking site has a sensible connection to your business. A builder getting links from construction suppliers, local councils, trade bodies and project features makes sense. A builder getting links from a random gambling blog in another country does not.
Authority means the site has earned trust itself. That could be a national publication, a respected niche blog, a local chamber of commerce, a supplier, a customer case study or a professional body.
Editorial context means the link appears naturally inside useful content. Someone chose to reference your business because it added value. That is very different from a paid sidebar link dumped onto a page with 80 other unrelated businesses.
Google’s spam policies on link spam are clear: links intended to manipulate rankings can be treated as spam. That includes paid links that pass ranking signals.
What makes a good backlink?
A good backlink normally has four things going for it: it comes from a real website, it is relevant, it sits in useful content and it was earned for a proper reason.
A real website has real readers. It publishes content for humans, not just search engines. It has an audience, a purpose, contact details, decent pages and a reason to exist beyond selling links to anyone with a PayPal account.
Relevance is where many businesses get stitched up. If you’re a Cheshire roofing company, a link from a local builder, property maintenance firm, roofing supplier, trade directory or local news article has a sensible connection. A link from a generic lifestyle blog covering pet food, forex trading, CBD oil and “best boilers in Barnsley” is probably rubbish.
Editorial placement matters too. A link inside a genuine article, case study, supplier page or local feature is usually stronger than a footer link or author bio link on a fake guest post.
For example, a travel article about gorilla trekking could sensibly reference a licensed Uganda safari operator. That is topical. The same link pointing to a Cheshire electrician would look weird as hell.
Good links pass the common-sense test.
What makes a bad backlink?
A bad backlink usually comes from a site that exists to sell links, manipulate rankings or bulk-publish thin content. Once you’ve seen a few, they’re not hard to spot.
The obvious ones are link farms. These sites publish hundreds or thousands of articles on completely unrelated topics. One day it’s “best accounting software”, the next it’s “how to choose a dog bed”, then “emergency locksmith London”, all written in the same dead-eyed content sludge.
Irrelevant foreign sites are another common one. There’s nothing wrong with international links if they make sense. But if you run a local plumbing business in Crewe and you suddenly have links from unrelated sites in countries you’ve never traded in, that’s not authority. That’s someone buying a cheap package and hoping you don’t notice.
Other bad signs include:
- Pages with no real traffic or audience
- Articles clearly written only to insert links
- Exact-match anchor text repeated again and again
- Sites linking out to every industry under the sun
- “Write for us” pages that accept anything
- Paid link networks pretending to be genuine blogs
If your previous agency built these and called it “authority building”, you were sold crap. It happens a lot.
Good backlinks vs bad backlinks: the quick comparison
Here’s the simple version. You don’t need to be an SEO expert to smell trouble.
| Link factor | Good backlink | Bad backlink |
|---|---|---|
| Website type | Real business, publication, organisation or niche site | Fake blog, link farm or paid network |
| Relevance | Connected to your industry, location or audience | Completely unrelated topic or country |
| Placement | Naturally included in useful content | Forced into thin content or dumped in a list |
| Anchor text | Natural wording, brand name or sensible phrase | Repeated exact-match keyword stuffing |
| Purpose | Helps readers find something useful | Exists mainly to manipulate rankings |
The best test is this: would the link still make sense if Google did not exist? If yes, it might be a good link. If no, it is probably SEO theatre.
How to check your existing backlinks
Start with Google Search Console. It is free, and it shows a sample of the sites linking to you. It will not give you every detail an SEO tool would, but it is enough to spot obvious problems.
Here’s the basic process:
- Open Google Search Console and choose your website property.
- Go to the “Links” report in the left-hand menu.
- Review “Top linking sites” to see who links to you most often.
- Review “Top linked pages” to see which pages attract links.
- Export the data if you want to check it properly in a spreadsheet.
You’re looking for patterns, not one-off weirdness. Every site gets spammy links eventually. Google knows the internet is a grubby place. A few random junk links are not usually worth panicking about.
What you should worry about is volume and intent. If half your backlinks come from obvious guest post farms, unrelated foreign blogs, scraper sites and keyword-stuffed anchor text, that’s a different story.
If rankings dropped after an agency “built links”, compare the timing. Link reports, ranking drops and manual action messages can tell you a lot. If technical issues are also involved, proper technical SEO checks should be done before blaming links alone.
What a toxic backlink profile looks like
“Toxic backlink” is a phrase SEO tools love because it sounds terrifying and helps sell subscriptions. Not every link labelled toxic is actually dangerous. Some are just low-quality noise that Google ignores.
A genuinely risky backlink profile usually looks deliberate. It shows a pattern of manipulation.
Common signs include lots of links from unrelated websites, repeated commercial anchor text, sitewide footer links, obvious paid guest posts, private blog networks and sudden spikes from sites with no connection to your business.
If you have a manual action in Google Search Console for unnatural links, take it seriously. That means Google has flagged link manipulation. You will usually need to identify the bad links, try to remove the worst ones and submit a reconsideration request.
The disavow tool exists, but it is not a toy. Google describes it as an advanced feature. Use it when you have a serious unnatural link issue, not because an SEO tool turned a few boxes red. Disavowing good links by accident can do more harm than good.
If you suspect a real problem, get the links reviewed properly before pressing buttons.
Why local backlinks can beat big-looking random links
For local businesses, relevance often beats raw metrics. A link from your local paper, council event page, charity sponsor page, chamber of commerce, local supplier or community organisation can be far more valuable than a random “DA40” blog nobody reads.
This is where many backlink reports mislead business owners. Domain Authority, Domain Rating and similar scores are third-party metrics. They can be useful clues, but Google does not use them directly. A link can have a nice-looking score and still be completely irrelevant.
If you’re trying to rank in Cheshire, a genuine local mention helps Google connect your business with the area you serve. It also builds trust with real people. That matters for local SEO, Google Maps visibility and AI-style search results where credibility is pulled from several sources.
Good local backlinks can come from:
- Local newspapers and magazines
- Business associations and chambers
- Suppliers and partners
- Sponsorships and community events
- Relevant local directories
- Case studies from customers or collaborators
This is why proper link building is not about buying links by the kilo. It is about earning mentions that make sense for your business, your location and your customers.
Red flags when an agency promises backlinks
If an agency promises a fixed number of backlinks every month without explaining where they’ll come from, be careful. That is often the start of the nonsense.
Good link building is messy. It involves research, outreach, relationships, PR angles, supplier opportunities, local relevance and decent content. Bad link building is easy. You buy a spreadsheet of placements and hope the client never checks.
Before agreeing to backlink work, ask these questions:
- Can I see examples of websites you typically secure links from?
- Are links paid, earned, sponsored or guest-post based?
- Will paid links use rel="sponsored" or rel="nofollow" where appropriate?
- How do you judge relevance, not just authority metrics?
- Will I get the actual URLs in my report?
- What anchor text will you use?
- Do you build links from private blog networks?
- What happens if a link is removed?
Be especially wary of guarantees like “100 DA50 backlinks for £99”. That is not SEO. That is someone firing your website into a link sewer and calling it strategy.
A decent agency should be able to explain why each link helps. If they hide behind jargon, vague reports or “proprietary methods”, push harder. It’s your website on the line, not theirs.
Frequently Asked Questions
How many backlinks do I need to rank? There is no fixed number. It depends on your competition, location, industry, website quality and the strength of the links. A local electrician may need only a handful of strong local links. A national ecommerce site may need hundreds of quality mentions. Quality and relevance matter more than raw count.
Can bad backlinks get my site penalised? Yes, bad backlinks can cause problems if they are part of an obvious attempt to manipulate rankings. Google may ignore many spammy links automatically, but unnatural link patterns can still lead to ranking drops or manual actions. Do not panic over every junk link, but do investigate clear patterns.
What is domain authority and does it matter? Domain Authority is a third-party score created by SEO tools, not Google. It can help compare websites at a glance, but it should never be the main reason for wanting a link. A lower-score local or industry-relevant site can be more useful than a high-score irrelevant blog.
Should I pay for backlinks? Paying for links that pass ranking signals is against Google’s guidelines. Paying for legitimate PR, sponsorships, advertising or content placement can be fine if links are marked properly with nofollow or sponsored attributes when needed. If someone is selling guaranteed ranking-boosting links in bulk, walk away.
