Free data or paid panels? ONS, Google Trends, YouGov and Prolific compared

What to take away

Free data sources named

Office for National Statistics (ONS) is free and covers population, employment and business counts by UK region. It suits market sizing and local briefs. It will not explain buying motivation.

Nomis, run by ONS, offers free local labour market data down to ward level. It suits recruitment and skills content. It needs interpretation because definitions change over time.

data.gov.uk is a free catalogue of UK government datasets. It suits policy and public sector briefs. Quality varies by department, so check the publisher and update date.

Google Trends is free and shows relative search interest over time. It suits seasonality and language checks. It gives no absolute volume, so pair it with another source.

Google Keyword Planner is free with a Google Ads account. It gives keyword volume ranges and competition estimates. Ranges are broad, and you may need spend to see exact numbers.

The UK digital strategy sets out skills and business support themes. Use it to frame why clients ask for digital-first content.

Paid panels and polling tools named

YouGov runs a large UK panel and sells survey fieldwork. Pricing is quote-based, so ask for sample size and incidence. It suits brand, politics and public opinion. Public reports often show methodology.

Ipsos offers UK omnibus surveys. Pricing is quote-based per question or wave. It suits quick national snapshots. Check whether your question can share a survey with other clients.

Kantar sells panel access and brand tracking. Pricing is quote-based and usually annual. It suits long-term tracking. Smaller agencies may find minimum spend a barrier.

Prolific connects researchers with UK participants. Researchers pay a minimum reward of £6 per hour plus a service fee. It suits academic-style and niche studies. Samples are not always representative of the whole UK.

Pollfish offers self-serve mobile surveys. Public pricing starts at around $0.95 per complete. It suits short consumer polls. Complex B2B quotas cost more and may need a quote.

SurveyMonkey Audience adds a panel to SurveyMonkey. Public pricing starts at around $1 per complete. It suits simple surveys with fast turnaround. Niche audiences can cost more per response.

Dynata and Cint are panel marketplaces. Pricing is quote-based and depends on incidence. They suit agencies needing multiple panel sources. Ask about source mix and fraud checks.

What to check before signing

Check lawful basis, processor or controller role, retention, and export format. A tool that cannot explain its panel is a risk. Your client's privacy notice must match the tool.

Where free beats paid

Free sources win on trend history, geography and cost. Paid sources win on motivation, language and speed. Most briefs need both, but rarely at the same volume.

Compliance sources that shape what you can publish

The Online Safety Act 2023 sets duties for services hosting user content. Community briefs need to know which duties touch the client.

The sanctions guidance explains what happens when marketing breaks advertising rules. It is useful when a client wants an aggressive claim.

Build a short compliance checklist into every brief. It takes an hour and prevents a rewrite.

How to sequence tool purchases

Start with the question. For market size, use ONS, Nomis or data.gov.uk. For motivation, buy fieldwork from a named panel.

Then check integration. A tool that cannot export cleanly wastes analyst time. The tool implementation guidance for England teams covers handover points.

If you want the wider supplier picture, the tools and supplier guide for 2027 sets out how platforms, panels and agencies fit together.

Set a review date. Panel contracts renew quietly, and a source nobody reads is a cost with no output.

Common questions

Are free data sources enough for a content strategy?

For sizing and search demand, often yes. ONS and Google Trends rarely explain motivation, so pair them with a small paid study.

Do I need a panel if I already have client data?

Not always. First-party data is usually stronger, provided consent covers the new use. Check that before buying anything else.

Which sources should a small agency prioritise?

ONS, one search demand tool such as Google Trends, and one panel provider such as Prolific. Add specialist sources only when a brief demands them.

How do I compare providers fairly?

Ask for methodology, sample sizes, retention periods and export formats. Compare answers, not sales decks.
