Overall Satisfaction with Optimizely Web Experimentation

We are using Optimizely for experimentation. We have mainly been testing to optimise checkout conversion and have been leveraging these findings to obtain buy in to test other areas of the site.
The tool has been excellent in ensuring we build stable and performant tests, and the service from the CSM has been excellent.

A big challenge we have is velocity due to very little resources. We have used Rapid X, but are now looking to leverage an Optimizely partner such as creative cx to ramp up velocity to obtain more learnings and build a test and learn culture

Pros

  • Very quick and easy to build tests
  • We were quite impressed that it didn't significantly degrade page performance.

Cons

  • The reporting area could be a bit more user friendly
  • Would love for to have better features for low traffic sites so that we can reach significance quicker.
  • From the small tests we have ran, we have managed to bring in £6m incremental revenue
  • We have mitigated the risk of implementing loss making features
  • Its helped build a test and learn culture within the teams
The product is extremely scalable, we have rolled out in all our transactional domains.
Unfortunately experimentation is not really mature in our team, so we have mainly just used optimizely for launching A/B tests. We have not been able to leverage the tool for any other reason
Optmizely is much more performant product. We have witnessed less issues with page performance on Optimizely and have no issues with flickering. We had these issues with Maxymiser.

Yes

It’s very easy to build tests with very little technical dependencies i.e we are not tied to our internal release.

The web feature is great to quickly validate concepts without investing too much time.

We are looking to move to an agency model, so the web tool should easily allow the agency build tests on the client side.
