Good Backlinks: What Makes a Link Worth Having (and Where to Get Them)

At a glance

• A good backlink is a followed, contextual link from a real, relevant site that would still be worth having if no SEO tool existed.
• Metrics like DR, DA and Trust Flow are each vendor’s estimate. Use them to screen sites, not to define quality.
• For a small business, the most reliable good links are editorial mentions earned with useful data, links from tools and partners you work with, and links from blogs you own.
• Owned links are the only good backlinks you fully control.
• Skip free backlink lists, sitewide footer links, link exchanges at scale and bought PBN links.

This guide gives you a checklist for judging any linking site, ranks the places good links come from by how reliable they are for a small site, and lists the “good backlinks” that aren’t.

What makes a backlink good

Six things separate a link that helps from one that just adds to a count.

1. The site is relevant. A link from a site in your industry, or listing businesses in your area, is worth more than a link from a random blog. If you’re a beautician, links from spas, beauty business listings and style guides make sense. The same links from a mechanic and a structural engineer don’t, and in our view search engines are likely to give them little weight.
2. The page is relevant too. A link on a page about your topic, from a site that covers several topics, beats a link on that same site’s page about something unrelated.
3. It’s a real site. It has its own visitors, its own links from other sites and content written for people. A site that exists only to host links passes little, however good its metrics look.
4. It’s in context. A link in the body of an article, in a sentence that explains why it’s there, is worth more than one in a footer, sidebar, author bio or list of 200 links.
5. The anchor reads naturally. Brand names, URLs and descriptive phrases, varied from link to link. The same exact-match keyword on every link is a pattern.
6. It’s followed and likely to stay. A normal link counts more than a nofollow one, and a link on a page that will still be there next year counts for longer than one in a news feed that drops off in a week.

The quality checklist

Use this before you pitch a site, accept a guest post, or buy an expired domain to build a blog on. It’s adapted from the checklist in our PBN guide for vetting expired domains, and the thresholds come from that guidance. They’re minimums for an expired domain, so treat them as a floor for any linking site, not as a target.

Check	What you’re looking for	How to check
Strength of its top links	Its best backlinks come from real sites and are likely to stay live	Ahrefs, Majestic, Semrush or Moz
Niche relevance	The site, and ideally the page, is about your topic	Read it, then check its top pages in a backlink tool
Basic strength	At least 10 Ahrefs Domain Rating and 10 or more referring domains. Below that, results are questionable.	Ahrefs (DR), Majestic (Trust Flow and Citation Flow)
Referring domains vs referring IPs	The ratio of external linking domains to linking IPs is below 10. A high ratio suggests many linking sites on the same servers.	Ahrefs, Majestic, Semrush
Clean link and anchor profile	Nothing from or about pharma, adult or gambling sites in its links or anchors	Anchors and referring domains reports in any of the tools
No recent link loss	It hasn’t lost most of its backlinks in the last few months	The lost-links history in your tool
Indexed in Google	The site and the linking page show up in Google	A site:example.com search

Domain Rating, Domain Authority and Trust Flow are each a vendor’s own score, built from that vendor’s crawl. They’re useful for screening a long list quickly. They don’t define quality, and a site can score well while failing every other check above.

Good backlinks ranked: from most to least reliable for a small business

Here are the main sources of good links, ranked by how reliably a small site can get them and keep them.

1. Editorial mentions earned with useful data

Everyone loves useful data. If you can publish fresh, useful numbers for any industry (a survey of your customers, prices you track, results from your own tests), people in that industry will link to it. The key word is useful: accurate data about a topic nobody in your niche cares about won’t attract links. Long-form guides with original research and real detail work the same way. You don’t need a set word count. You need something other sites would rather cite than rebuild.

These are the best links you can get. They’re also unpredictable, which is why they’re first on quality and not first on reliability for every site.

2. Links from tools, suppliers and partners you work with

Write an honest review of a tool you use, or a case study of how you use it. Companies like being reviewed by real customers and often link to those reviews or feature them. The same goes for suppliers, partners and associations you’re already part of. These links are relevant by definition, because they come from your actual business relationships.

3. Local and industry citations

Business directories, chambers of commerce and industry associations are standard links for a real business. They rarely move rankings alone, but a business without them looks odd. Our guide to local SEO backlinks covers which ones matter.

4. Guest posts

A guest post on a real, relevant site, with a contextual link in the body, is a good link. The quality varies wildly, because many sites that accept guest posts exist to sell them. Use the checklist above on every site before you write anything. Our guide on how to build backlinks covers outreach and guest posting step by step.

5. Owned links from your own blogs

The only good backlinks you fully control. A link from a blog you own goes where you decide, with the anchor and topic you choose, and nobody can remove it, sell the page to your competitor or add a sponsored tag. Build your blogs on expired domains that pass the checklist above, give them real content, and keep the network private. Host them on Easy Blog Networks: plans start at US$39/month for 10 blogs, with a 7-day free trial.

Owned links rank fifth here because they take the most upfront investment: domains, hosting and content for each blog. For a site in a competitive niche, they’re often the most reliable source on the list once the network exists. Our guide to building your own network covers how to start.

6. Paid placements

Last, and with a warning. Paying a site to place a link gets you a link fast, but you’re renting it. The seller can remove it, mark it as sponsored, or sell the same page to everyone in your niche, and buying links for ranking purposes is the first example of link spam in Google’s spam policies. Don’t buy links, and above all, don’t buy PBN links. The P stands for private: a network that sells links to anyone is a public network, and public networks are much easier for Google to find and penalize. Build your own instead. If you’re weighing it anyway, our guide on whether you should buy backlinks goes through what you actually get for the money.

Where on the page and to which page

Where the link points matters almost as much as where it comes from.

• Homepage or deep pages. Your homepage is the page least likely to change URL, so links to it are safe and build your whole site’s strength. But a homepage rarely ranks for your money keywords. Point most links at the pages you want to rank, and some at the homepage, the way a real site’s links are spread.
• Keep target URLs stable. If you change a URL or delete a page, every link to it leads nowhere unless you redirect it. Redirect every old URL that has links.
• Once or twice per post. A link in every paragraph looks like spam and helps nobody. One link buried at the bottom of a page is less likely to be clicked. Place a link once or twice in each post, where it fits what the reader is reading at that point.
• Vary the anchors. Use your brand, the URL, and related words and conversational phrases. A library of posts all linking with the same keyword anchor is a footprint.

Bad “good backlinks”: what to skip

Plenty of pages selling “high authority backlinks” are selling these:

• Free dofollow backlink lists. If anyone can drop a followed link on a site, every spammer has too.
• Sitewide footer and sidebar links. One link repeated on every page of a site, usually paid. Widely distributed footer links are on Google’s list of link spam examples.
• Link exchanges at scale. Swapping links with one relevant partner is normal. Running a “link to me and I’ll link to you” scheme across dozens of sites is what Google’s spam policies call “excessive link exchanges.”
• Bought PBN links. Covered above. You get the risk of a network without the control.
• Social media “backlinks.” Social profiles are useful for traffic and for being found, but the links are almost always qualified. Our guide to social media backlinks explains what they count for.

FAQ

What is a high-quality backlink?

A followed link in the body of a relevant page, on a real site in your niche that has its own visitors and its own backlinks, with a natural anchor and a good chance of staying live.

Which backlink is most powerful?

An editorial link from a strong, relevant site, placed in context because the writer found your page useful. One of those can do more than dozens of directory or comment links.

What is a good number of backlinks?

Yes. Google still describes links as part of how it understands and ranks pages, and when most pages on a topic say the same thing, links are often what separates them.

How do I find good backlinks?

Look at who links to the pages ranking for your keywords, then run each candidate site through the checklist above. The sites that link to several of your competitors and pass the checklist are your best prospects.
