How We Rate

Every ranking on NerdBible is built on a transparent, consistent methodology. We want you to understand exactly how we reach our scores, and to trust that they are never for sale.

Our scoring framework

Each product receives a score out of 10, built from four weighted pillars that we adapt slightly per category:

• Core performance: how well the product does its main job, judged from independent lab or industry data, the provider's own documentation and what other reviewers found.
• Features, the depth and usefulness of what is included.
• Ease of use: setup, day-to-day experience and support quality.
• Value: real pricing, including renewals and add-ons, against what you get.

How we research

We do not test products ourselves. Each assessment is built from the providers' own plans, policies and documentation, independent lab results and audits where they exist, notices from regulators, and what other reviewers and users report, and every review lists its sources. For specialist or health categories we report what official bodies and specialist publications say.

Keeping things current

Prices, offers and product features change constantly. We re-check our comparisons regularly and display a "last updated" date on every page so you know how fresh the information is.

Independence

Affiliate relationships never affect our scores or the order of our rankings beyond the criteria above. If we earn a commission, we tell you. See our advertiser disclosure for details.
