The Better Bet matched-betting glossary is now live. Thirty short, definitional entries covering everything from "back bet" and "lay bet" to "gubbing" and "implied probability" — written by our editorial team, cross-linked to our deeper guides, and structured so both human readers and AI Overviews can use them as a clean reference.

Matched betting has its own vocabulary, and most beginner guides assume you already know it. This is the index page for the fix.

Summary#

• 30 terms, around 500 words each, cross-linked to our calculators, oddsmatcher, blog posts, and bookmaker hubs.
• Bylined across all seven of our editorial team — every entry carries a real human's voice and a named-author Person schema.
• Schema-marked as DefinedTerm for AI Overview citation, with a DefinedTermSet index page sitting on top.
• Updated as bookmaker products evolve — the entries are versioned, not frozen.
• Index lives at /glossary; each entry sits at /glossary/<slug>.

Why a glossary#

Matched betting's specialist vocabulary is a barrier for beginners and a reference need for almost everyone past the welcome-offer stage. Other UK comparison sites have rough equivalents — OddsMonkey runs about a dozen definitional entries, Outplayed about eight — but most of them stop at one-line dictionary glosses. A reader leaves knowing what "lay bet" means as a phrase and not what to do with it.

We've gone deeper. Every entry has an atomic answer of one or two sentences directly under the heading, a paragraph on why the term matters specifically inside matched betting, a worked example with concrete numbers and named operators, and a common-mistake call-out for the gotcha that beginners hit most often. The structure is deliberate: it's the format AI Overviews quote verbatim when answering definitional queries, and it's the format beginners actually find useful when they're three minutes into their first bet and need to look something up. The 30 entries are also a lattice of internal links — each one points to two or three of the others, plus to the deeper how-to guides, the calculators, and the bookmaker hubs. The link graph density on the site is now meaningful in a way it wasn't a fortnight ago.

What's covered#

The thirty entries split across four clusters.

Core mechanics and promotions (entries 1–20)#

Back bet · Lay bet · Lay stake · Liability · Qualifying bet · Qualifying loss · Free bet · SNR free bet · SR free bet · Bonus bet · Welcome offer · Reload offer · Best Odds Guaranteed · Extra place offer · Acca insurance · Bet builder · Money-back special · Profit boost · Bore-draw refund · Two-up offer

Risk and restrictions (entries 21–25)#

Gubbed · Stake restriction · KYC verification · Connected bookmakers · Wagering requirement

Strategy (entries 26–30)#

Dutching · Underlaying · Sequential laying · Greening up · Implied probability

How we wrote them#

Every entry follows the same structure: an atomic answer of one or two sentences directly under the heading, a "why it matters" framing that explains where the term lands inside an actual bet, a worked example with real numbers and named UK operators (Bet365, Smarkets, Coral, Paddy Power), and a common-mistake call-out for the gotcha that beginners hit. The format is deliberate. AI Overviews quote definitional entries verbatim when the atomic answer pattern is clean; beginners need the worked example more than the definition. We've structured each entry to serve both readers without compromising either, then bylined it to whichever of our team has the most direct knowledge — Sophie and Tom on the welcome-offer mechanics, Charlotte on the compliance and gubbing entries, Daniel on the strategy maths, Henry and Oliver on the seasonal and casino-side promotions, James on the technical underpinnings.

Where to start#

If you're new, start with back bet, lay bet, and free bet — those three terms are most of the cognitive load in matched betting's first hour. Then read our matched betting beginner guide for the pillar that ties them together, our free bets pillar for the SNR/SR mechanics, and try the free tutorial to see the maths happen with real numbers in your own browser.

The practical takeaway#

A glossary is reference content. It doesn't replace the cluster pillars or the calculators — it sits alongside them, the way a good dictionary sits alongside a textbook. The point of publishing this is partly to fill the obvious gap (every UK matched-betting site we checked had a thinner one), and partly because the entries themselves matter. Knowing what "liability" means before placing a £6.50 lay stake is the difference between a calm afternoon and an alarmed one.

If you've not started yet, the free tutorial walks you through two real bookmaker offers without payment details. Most members have around £40 in their bank account by the end. If you're already past the welcome phase, the strategy entries — dutching, sequential laying, greening up, and implied probability — are the four I expect long-time readers to keep open in another tab. The glossary is at /glossary, and it'll keep growing as new bookmaker products land.
