How do I ensure my keyword research with a search volume API is compliant with rate limits and attribution rules?

To stay compliant, treat the API as a licensed data source with two main constraints: rate limits and attribution/usage rules.

1) Respect rate limits

• Read the API docs carefully for:
  • requests per second/minute/hour
  • daily/monthly quotas
  • burst limits
  • concurrent request limits
• Build throttling into your app
  • Add client-side or server-side rate limiting.
  • Queue requests instead of firing many at once.
  • Use exponential backoff on 429 Too Many Requests.
• Cache results
  • Store keyword results and reuse them when allowed.
  • Avoid re-querying the same keyword unnecessarily.
• Batch requests if supported
  • Use bulk endpoints rather than single-keyword calls.
• Monitor usage
  • Track request counts, error rates, and quota consumption.
  • Alert before hitting limits.
• Handle retries safely
  • Retry only on transient failures.
  • Don’t retry aggressively on quota errors.

2) Follow attribution rules

• Check whether attribution is required
  • Some providers require a credit line in UI, reports, exports, or dashboards.
• Use the exact wording required
  • If the provider specifies a phrase or logo, use it exactly as written.
• Place attribution where required
  • Common places: footer, report appendix, settings page, export metadata.
• Preserve source labels
  • If you transform data, still identify the original source.
• Don’t imply ownership
  • Avoid wording that suggests the data is your proprietary dataset if it came from the API.
• Watch redistribution restrictions
  • Some APIs allow internal use but not reselling, republishing, or exposing raw data to end users.

3) Add compliance checks to your workflow

• Document the API terms
  • Keep a summary of allowed use, attribution text, and quotas.
• Create technical guardrails
  • Rate limiting middleware
  • Request logging
  • Quota dashboards
  • Attribution templates for exports and reports
• Review changes before launch
  • If you add new features like bulk exports or public dashboards, re-check the terms.

4) Practical implementation tips

• Use a token bucket or leaky bucket limiter.
• Store a per-keyword cache key with a TTL that matches the provider’s terms.
• When the API returns 429, stop sending requests and wait the suggested Retry-After period if present.
• Include attribution automatically in:
  • downloadable reports
  • UI footers
  • shared links
  • API-powered charts

5) Ask the provider if unclear

If the terms are ambiguous, contact the API vendor and ask:

• Can I cache results?
• How long can I store them?
• Can I show them in my app?
• Is attribution required in the UI, exports, or both?
• Can I redistribute results to clients/customers?
