Page Load Time - Comparing Optimizely & VWO

Page Load Time

We never slow you down

VWO uses asynchronous code to serve your campaign data, compared to synchronous code used by Optimizely.

Simply put, asynchronous means that the code will contact VWO servers in the background, download, and process the test package while the rest of your page continues to load and render in the browser as usual. It’s what keeps your visitors’ screens from flickering.

Optimizely’s synchronous code makes the browser wait until Optimizely can deliver the test package, long enough for visitors to notice.

And in the improbable case of our servers being unavailable, the original page gets loaded, ensuring that your visitors' experiences remain unaffected.

Note: Optimizely offers asynchronous code however, they recommend synchronous code.

Frequently Asked Questions

The first step between choosing VWO or Optimizely is to know the objective you want to achieve with your experimentation program. Do you wish to only run tests without a long-term plan? Do you wish to analyze your site visitors’ behavior or not? Optimizely only offers testing and personalization capabilities, while VWO provides everything that Optimizely does, along with the crucial visitor behavior analysis, program management, and even the option to re-engage with lost visitors.

Next, gauge your CRO team’s experimentation maturity or skill level. If you’re just getting started, you would need assistance and VWO offers industry-leading support with a 98% customer satisfaction rate. Irrespective of your skill level, VWO support is reliable and has a great UI that suits any skill level.

Lastly, what’s your budget? Optimizely is considerably expensive, while VWO is not. Getting a higher ROI from your experimentation program is more likely to be achieved with VWO.

VWO is a comprehensive CRO platform, and the only one you need for all your experimentation needs. Right from tracking your key metrics and gathering visitor behavior insights to running UI-based and more sophisticated tests, VWO allows you to do it all via a single connected platform.

You can also plan and manage your optimization pipeline in VWO. Optimizely only offers testing and personalization, that too at a high price point. VWO also has exceptional support and is compliant with most of the important internet laws.

No, Optimizely does not have the features that allow you to track key metrics and glean visitor behavior insights. VWO, on the other hand, has an Insights capability built specifically for this.
VWO Insights offers heatmaps, session recordings, on-page surveys, and form analytics so you can step into your visitors’ shoes and understand their pain points.

You can then use the insights you discover to optimize your digital experiences accordingly.

VWO’s plans are based on the features you need. VWO offers various products-
VWO Testing, VWO Insights, VWO Engage, VWO FullStack, and VWO Plan. For each of these products, you can opt for either the Growth, Pro, or Enterprise plan based on your team’s CRO maturity level.

You can either opt for these individual products or a combination of these under the Conversion Optimization Essentials or Experience Optimization Essentials plans. You also get a dedicated success manager from VWO to guide you with your CRO program with each plan.

VWO also offers Free Trial, while Optimizely does not. You can use the Free Trial to figure out your requirements and opt for the most-suited plan accordingly.

Self-hosting is a very niche feature, which VWO has also been focusing on. But the way we go about it is a little different from Optimizely and is tailored to suit our customers’ needs. We don’t have integrated setups for various CDNs like Optimizely.

We share the various files which you can execute easily.
VWO has 10 dynamic CDNs in various geographies that help reduce load time and ensure data security while complying with critical internet laws.

While VWO also offers an equally powerful configuration of the VWO SmartCode (implementation snippet), we don’t have the option of implementing it through the app.

Also, VWO’s SmartCode implementation is the best in the industry in terms of size and ease of usage.
Unlike in the case of Optimizely, you don’t need to pay extra for this. The various integrations with popular CMSes like WordPress, Joomla, etc. help you set up the VWO SmartCode in no time, and with robustness.

VWO has a MAB feature in beta right now and will be rolled out for general access soon!

Deliver great experiences. Grow faster, starting today.
