Bookmaker Rating Methodology
A transparent, data-driven formula — six pillars, fixed weights, no hidden criteria.
Transparent by design
Every bookmaker listed on 365BettingTips has been independently assessed against the same six-pillar framework. We disclose the formula so you can judge not just the scores, but the scoring itself.
Overall Score Formula
Score = Reliability ×22% + Odds ×22% + Lines ×18% + Bonuses ×13% + Live ×10% + Editorial ×15%
Each pillar scored 0–10 · weighted average = final rating out of 10
Fixed formula
Weights are set in advance and applied consistently to every operator — no ad hoc adjustments to favour a commercial partner.
Research-verified
Data gathered from regulator registries, TrustPilot, AskGamblers, and betting forums — authoritative sources you can check yourself, not screenshots.
Continuously updated
Odds margins are monitored daily. Bonus terms are checked weekly. Ratings are revised whenever material changes occur.
Six pillars, six weights
Each pillar contributes a specific percentage to the overall score. The breakdown reflects what matters most to sports bettors.
What each pillar measures
A detailed breakdown of the criteria behind every score. Nothing is a black box.

- Early line availability for key fixtures
Bonuses & Promotions
Weight: 13%- TRUE value assessed after wagering requirements and restrictions
- Automated bonus scoring: each offer gets a real value score (0–10)

- Ongoing promotions and loyalty rewards evaluated separately
Live Platform & Tech

- In-play bet acceptance speed and market suspension frequency

Editorial & Expert Review
Weight: 15%- Independent analysis across 5 structured sections
- Sections: reputation, welcome offer, payments, lines & odds, support
- Multi-stage AI data-gathering pipeline, verified by expert
- Review updated on a rolling schedule or following material changes
How a review is produced
Every rating is built on structured open-web research, AI analysis, and expert verification. Here is the three-phase process from open-web research to published score.
Open-Web Research
ResearchAll data is gathered from authoritative public sources — no manual account testing required. This covers four structured areas:
- Licensing & Profile — official site, licence verified against regulator registries (UKGC, MGA, Curaçao), company history, deposit limits, mobile apps, support channels
- Reputation & Reviews — feedback aggregated from TrustPilot, AskGamblers, Reddit betting communities, and independent betting forums: ratings, recurring complaints, payout disputes
- Payments Audit — deposit and withdrawal methods, limits, fees, and processing speed across cards, e-wallets, crypto, and bank transfers
- Markets & Odds Research — football line depth, average odds margins, league coverage (EPL, La Liga, UCL, African competitions), live betting and streaming features
AI Analysis
AIAn AI pipeline synthesises everything collected in Phase 1 into a structured, fact-based assessment:
- Five-section structured assessment: reputation, welcome offer, payments, lines & odds, support
- Each section scored 0–10, built strictly from the collected research — no filler or speculation
- Automated bonus value scoring: wagering multiplier, minimum odds, validity period, and restrictions all accounted for
Expert Verification & Automatic Rating
EditorialHuman oversight and an algorithmic formula combine to produce the final published score:
- Sophie Ward fact-checks the AI findings, corrects any errors, and signs off the final review — plain verdict, no promotional language
- Once the analysis is finalised, the system automatically computes the overall rating from all collected data using the six-pillar weighted formula
- No manual score adjustments — the exact weights are publicly disclosed on this page and applied uniformly to every operator
