Why these links matter more in 2026
Google rewards backlinks from high-trust domains, and AI search engines (ChatGPT, Claude, Perplexity, Gemini) weight references from authoritative sources when they decide which businesses to recommend. A link from a domain Google trusts is worth more than ten from domains it does not.
Here is what most UK businesses miss. The UK government and the devolved administrations run free supplier and tender portals, and registering or winning a listed contract creates a record on a gov.uk domain, one of the most authoritative domain types on the web. The link is usually nofollow, so the value is the trust signal and the procurement access, not link equity. Almost no business outside the tender world claims them.
Important: legitimate suppliers only
The Tier 1 portals are real procurement systems for verified suppliers. Only register if your business genuinely supplies the goods or services those portals buy. Listing without legitimate supplier capability risks rejection or removal. Treat them as procurement opportunities first and SEO leverage second. The other tiers do not have this restriction.
The checklist
50 free UK backlink sources, tiered by leverage
The Free Backlinks List sheet groups every source by region and tier, with the URL, the listing type, and a status column to track what you have submitted, verified, and live. Make a copy and work top-down through the UK rows.
Tier 1 - The gold
UK government and procurement portals
The strongest, hardest-to-fake signals on this list. Registering as a supplier, or winning a listed contract, earns a genuine presence on a gov.uk portal. Most are nofollow or login-gated, so the value is the trust signal and the procurement access. Only register if your business genuinely supplies what these portals buy.
- Contracts Finder. Free supplier profile and alerts; publishes England public-sector contracts, and award notices name the winning business on a gov.uk domain
- Find a Tender Service. The UK-wide portal for higher-value contracts under the Procurement Act 2023, with free registration, alerts and award notices
- Supplier Registration Service. The central Cabinet Office supplier identity used across bids, a legitimate gov.uk supplier record
- Government Commercial Agency frameworks. Join a framework agreement and appear on the framework register; the former Crown Commercial Service, rebranded to the GCA in April 2026 (both names still find it)
- G-Cloud and the Digital Marketplace. For tech, SaaS and digital suppliers, a public listed profile in the government's cloud-services catalogue
- Public Contracts Scotland. Scotland's devolved portal, with free registration, alerts and supplier-named award notices
- Sell2Wales. Wales' devolved portal from Business Wales, with free registration and opportunity alerts
- eTendersNI. Northern Ireland's portal (a free DUNS number is needed), with a free supplier profile and alerts
- Local council supplier portals. Councils run their own e-tendering systems on In-Tend, ProContract and Jaggaer; registering creates a listed supplier record for that authority
Tier 2 - Non-negotiables and directories
UK business directories and citations
The top three are the must-have local-SEO citations. The rest are UK directories worth claiming where they fit. Most are nofollow, but they anchor your NAP and entity across UK discovery and AI answers.
- Google Business Profile. The number-one local citation and the foundation of local and map visibility
- Bing Places. Microsoft's equivalent, which feeds Bing and Copilot; import straight from your Google profile
- Apple Business Connect. A free listing feeding Apple Maps, Siri and Spotlight, increasingly important for local discovery
- Yell. The largest UK directory, with a free basic listing and a long-standing citation
- Thomson Local. An established UK directory with print heritage and a free business listing
- FreeIndex and Scoot. Large UK business and review directories with free owner-managed profiles
- UK Small Business Directory. A dedicated free listing for UK SMEs
- 192.com. A UK people and business finder with a free business listing
- Yelp UK. A free listing and reviews, strong for hospitality and local trades
- Cylex UK, Hotfrog UK, Brownbook, TouchLocal. Free UK listings on established directory networks; claim the ones that fit
Tier 3 - Chambers and industry bodies
UK chambers of commerce and industry bodies
Membership can be paid, but the member-directory listing that comes with it links out and sits on a trusted, relevant domain. Trade-body directories are low-spam and geo-relevant.
- British Chambers of Commerce. The route to your accredited local chamber via the Find a Chamber directory
- Your local accredited chamber. A member-directory listing links to your site with high local relevance; some chambers offer free connect or associate tiers
- Federation of Small Businesses. Member benefits can include a directory presence and business-support pages
- Federation of Master Builders and sector bodies. Trade-body public directories like Find a Builder, RICS, BIBA and REC list members; find the association for your sector
- Living Wage Foundation. Becoming an accredited Living Wage employer earns a public listing, an earned credibility link
Tier 4 - Earned only
Earned .ac.uk and .gov.uk link opportunities
Tactics, not signup pages. Never buy .ac.uk or .gov.uk links or use guaranteed academic-link services; they are almost always hacked pages or link schemes that trigger manual actions. Earn them by being genuinely useful.
- University resource and library pages. Create a genuinely useful free resource, then pitch the relevant department or librarian for their resources page
- Student-discount and student-deals pages. Offer a real student discount; student union and careers pages list participating businesses
- Genuine scholarship pages. Fund a real, well-run scholarship and universities may list it; only if it is administered properly, since spammy scholarship schemes are a known abuse
- Guest lectures and alumni features. Deliver a talk or be featured as an alumnus; departments often link speakers and case studies
- Research-data pitches and council partner pages. Publish original research academic departments cite, and join genuine local-authority business-support schemes that list participants
Tier 5 - Earned editorial
Journalist and PR request platforms
These earn the dofollow editorial links that outweigh every directory here, through expert commentary UK journalists cite. HARO is defunct; these are the live UK-usable routes.
- ResponseSource. The main UK journalist-request service with tens of thousands of UK journalists; strong for knowing what UK press wants
- Qwoted. A free tier to pitch expert commentary, with heavy UK usage
- Featured. A free tier where you answer journalist and editor questions for expert citations
- Newspage. A UK service connecting SMEs and experts with journalists, strong in finance and property
- SourceBottle and Help a B2B Writer. Free source alerts and B2B queries open to UK experts
- #journorequest. Free, real-time UK journalist call-outs on X and Bluesky; monitor and respond directly
Tier 6 - Startup and tech
UK startup, tech and software directories
Free profiles for tech, SaaS and service businesses. Crunchbase and Product Hunt links are nofollow, valuable for referral, brand entity and AI discovery rather than authority.
- Crunchbase. A free company profile that acts as a canonical entity record for AI and knowledge panels; the link is nofollow
- Product Hunt. A free product launch listing with a big referral spike and a strong brand signal; the link is nofollow
- F6S and BetaList. Free startup profiles, with dofollow reported on free listings
- Wellfound. A free startup company profile for brand and talent visibility
- Startups.co.uk. A UK-specific startup and small-business directory with editorial coverage
- Clutch, G2 and Capterra UK. Free listings for agencies, service firms and software vendors on high-intent B2B platforms
How to use the list
- Build top-down. Tier 1 first. The government and procurement records are slower to earn but worth more than the lower-tier directory listings.
- NAP consistency is non-negotiable. Name, Address, Phone must be identical across every listing. Inconsistency confuses Google, weakens local rankings, and creates duplicate listings that compete with your real ones.
- 20 clean high-authority listings beat 200 messy ones. If you cannot maintain a directory in a quarterly cycle, do not register.
- Many of these links are nofollow. That is fine. The value is citation consistency, brand-search dominance, and the references AI search engines cite, not raw link equity. Earn the dofollow editorial links through the PR platforms in Tier 5 and the Digital PR guide below.
- Never buy government or academic links. Paid .gov, .edu, .ac.uk and "guaranteed" placement services are link schemes that risk a manual action. Every source here is earned or free-to-claim.
