Check Google's current testing requirements before choosing dates. - [Crowdtesting vs in-house QA: which do you need?](https://testlancer.com/guide-crowdtesting-vs-in-house-qa.html): In-house QA checks that your product works as specified, using your team's knowledge and test plans. Crowdtesting sends the product to many real users on their own devices, finding device-specific bugs and usability problems your team is too close to see. Most teams get the best results by combining both. - [How to write instructions testers can follow](https://testlancer.com/guide-writing-tester-instructions.html): Good tester instructions state one goal, list numbered steps with one action each, say exactly what evidence to submit, ask specific questions, and give a time estimate. Clear instructions produce comparable, useful feedback and fewer rejected submissions. - [What makes user feedback useful?](https://testlancer.com/guide-useful-user-feedback.html): Useful user feedback is specific (which screen and what happened), reproducible (steps someone else can follow), evidenced (screenshot or recording), honest (including negatives) and contextual (device, OS and network). Feedback with these five qualities can be acted on quickly. - [How to get more genuine Google reviews](https://testlancer.com/guide-genuine-google-reviews.html): To get more genuine Google reviews, share your official Google review link with real customers at the right moment — right after a successful purchase or service — using email, WhatsApp, receipts or QR codes, and reply to every review. Never buy, write or incentivise reviews; it breaks Google's policies and consumer law. - [What is UGC and how can you use it for your app?](https://testlancer.com/guide-ugc-for-apps.html): UGC (user-generated content) is photos and videos of real people using your product, created for your own ads, app store pages and social accounts. Unlike influencer marketing, UGC creators don't need a large audience — the value is authentic-looking content, with usage rights agreed upfront. ## Key pages - [How it works](https://testlancer.com/how-it-works.html) - [Pricing](https://testlancer.com/pricing.html) - [FAQ](https://testlancer.com/faq.html) - [Trust & safety](https://testlancer.com/trust-safety.html) - [About](https://testlancer.com/about.html) - [Glossary](https://testlancer.com/glossary.html) - [Contact](https://testlancer.com/contact.html)
