How will Optimizely Classic affect my pageload times? Will my site lag?
The short answer: no. Your site shouldn't lag, and any delay to pageload times should be undetectable to the human eye.
We understand that even small increases in page load times must be taken seriously, so we do everything we can to make sure that Optimizely's impact on your page is as small as possible.
There are two Optimizely endpoints that receive web requests from your pages while an Optimizely Classic experiment is running:
- Your visitors' browser sends tracking requests to Optimizely
Your visitors' tracking requests are made when your visitors land on a page containing your Optimizely snippet. This is how Optimizely collects analytics on your conversion goal performance. These requests are asynchronous, non-blocking, and only occur for visitors that have been placed in at least one experiment. They should have no effect on your page load time.
How does Optimizely Classic affect my search ranking or SEO (Search Engine Optimization)?
Google permits and encourages A/B testing and has stated that performing an A/B or multivariate test poses no inherent risk to your site’s search rank. However, it is possible to jeopardize your search rank by abusing an A/B testing tool for purposes such as cloaking. We have more in-depth information in our SEO and search ranking article.
What version of jQuery does Optimizely Classic use?
Optimizely Classic uses jQuery version 1.11.3 by default.
How do I find more information about the Optimizely API? Where do I generate a token?
The Optimizely REST API lets you create and manage Optimizely projects and the experiments inside of them. The API is RESTful and encodes data in JSON. The sections below explain how to authenticate with the API, form requests, and consume responses.
