One of Pertento’s core strengths is the ability to launch and manage experiments instantly through its platform, without any engineering work or delays. The moment you’re ready to run a test, Pertento can push it live to your site with a single click. There’s no waiting for code deployments or scheduling required – the change is activated for your visitors right away via Pertento’s lightweight snippet. Similarly, you can pause or stop an experiment at any time from the interface, and the change will be reverted immediately. This instant deployment capability allows teams to iterate and respond quickly.

Launching an Experiment

  1. 1Prepare the Experiment: Ensure that you have configured your experiment’s variations (e.g. using the Visual Editor) and set the targeting rules and goals. Double-check that everything is previewing correctly.
  2. 2One-Click Launch: In the Pertento platform, locate the experiment and click the Launch (or Start) button. Confirm any prompts. Pertento will immediately activate the experiment on your live site. The selected percentage of your traffic (depending on how you configured the split, usually 50/50 by default for A/B) will start seeing the variant version instantly.
  3. 3No Deployment Delay: Under the hood, Pertento’s script delivers the changes to your users without needing to modify your site’s code or deploy new files. This means as soon as you hit launch, the experiment is live. There’s no downtime or waiting for a release cycle – a major time saver for marketing and product teams.
  4. 4Verify Live Status: After launching, you can verify that the experiment is running. For example, use an incognito browser or a test mode to see that the variant is appearing as expected to users who match the targeting. Pertento’s interface will typically indicate the experiment’s status as “Running” and start collecting data.

Pausing or Stopping an Experiment

  • Immediate Pause: If you need to halt the experiment (for example, if you notice an issue or the test has reached significance), you can pause it from the Pertento dashboard. Click the Pause or Stop button next to the running experiment. Pertento will stop serving the variant to users right away. Anyone loading the page after that point will only see the original (control) experience, as if the test were off.
  • No Code Rollback Needed: Because Pertento injects the variant dynamically, pausing an experiment doesn’t require any code rollback or site redeploy. The change is simply no longer applied, instantly reverting everyone to the original experience. This makes it safe to turn tests on or off as needed without risk.
  • Resume (if applicable): If the platform supports resuming, you could restart a paused experiment by clicking Resume. The variant would again be delivered immediately. (If not, you can always launch a new test with the same settings.)

Speed and Flexibility Benefits

  • Fast Iteration: Instant launches mean you can run experiments back-to-back or make quick adjustments. If an idea arises, you can set up the test and have it live within minutes. This agility helps you capitalize on opportunities or react to issues (for instance, quickly A/B test a fix for a conversion drop).
  • No Developer Dependency: Non-technical team members can deploy tests on their own. Once the Pertento snippet is installed on the site, launching tests is handled entirely in the Pertento UI. There’s no need to involve engineering for each experiment release, freeing developers for other work and empowering growth teams to move faster.
  • Controlled Rollout: With the ability to start and stop instantly, you have fine-grained control. For example, you might launch a test in the morning and decide by afternoon to stop it if early metrics are negative. Or pause all experiments during a high-traffic event (like Black Friday) with confidence that pausing takes effect immediately.
  • Concurrent Experiments: Pertento’s deployment system likely supports running multiple experiments simultaneously (as long as they target different elements or audiences). The instant launch feature applies to each experiment independently, so you can manage a portfolio of tests and turn individual ones on/off without affecting others.

In summary, Pertento’s instant launch capability simplifies the experiment lifecycle. You can go live with a test and take it down on demand – all with a button click. This speed and control reduce the friction of experimentation, allowing for continuous optimization without the usual delays associated with deployment.
