FAQ

Common questions

How many reviews do I need to raise my rating?+

It depends on your current rating and review count. Raising an average gets harder as your review count grows — this calculator does the exact math and shows the reviews and time required at your pace.

Can I reach 5.0 stars?+

A perfect 5.0 is nearly impossible to sustain — it requires every single review to be 5★. Most strong businesses target 4.7–4.8★, which is the sweet spot for trust and local ranking.

Is it safe to ask customers for reviews?+

Yes — asking is compliant as long as you ask everyone (no gating), attach no incentives, and never post fake reviews. That's exactly how we grow reviews for our clients.

Do you buy or sell reviews?+

Never. Fake and purchased reviews violate platform policies and the FTC rule, and get detected and removed. We only generate genuine reviews from your real customers.
