Cut Your A/B testing expense with Convert and other Optimizely Alternatives

Optimizely has made a name for itself as one of the pioneer A/B testing tools.

But if its price, compulsory yearly commitment, or something else about it doesn’t align with your marketing strategy or budget, there are abundant alternatives to switch to something else.

Many of these Optimizely alternatives match its features for a much lesser price — with extra perks.

In this article, we break down the good, the bad, and the ugly of Optimizely, and explore 8 Optimizely alternative tools including Convert Experiences, Kameleoon, OmniConvert, VWO, Convertize, Apptimize, Google Optimize, AB Tasty.

Who is Optimizely? 

Optimizely is an A/B testing software and experimentation platform geared towards developers, CRO specialists, and marketers to run a variety of experiments. 

It is a monster of a tool, sophisticated, with a price tag to match. 

But for many, it is too much. Too many features that go unused and a cost that businesses just can’t justify.

If you can relate to the previous statement, you will be happy to see the list of Optimizely competitors that rival this Goliath in features and benefits, and protects your budget.

Optimizely Pros and Cons

Optimizely is the granddaddy of A/B testing.

We see what individual CROs have to say about Optimizely, but what do Optimizely formal reviews look like on the top aggregated rating sites like G2, TrustRadius, Software Advice, Capterra? Here is the breakdown for each…

Optimizely G2C Rating: 4.3 out of 5 ☆  

Optimizely TrustRadius Rating: 8.6 out of 10 ☆ 

Optimizely Software Advice Rating: 4.5 out of 5 ☆

Optimizely Capterra Rating: 4.6 out of 5 ☆  

Optimizely performance is solid, but the price is prohibitive. Not only is it expensive, but they force you to commit to a yearly plan.

Price: Not transparent

Is Optimizely only for big companies, not small or startup companies?

In addition, EpiServer, a content management company, has recently acquired Optimizely. More on this below.

How to Use Optimizely for A/B Testing?

To use Optimizely for A/B testing, you either need to download the desktop app or use the web-based optimization platform. They look and feel the same, but the desktop app is faster.

Steps to launch your A/B test on Optimizely:

  1. Click the “Create New” button and choose “A/B test” from the menu that pops out.
  2. Name your experiment, add a description if you want, and choose your target.
  3. On the experiment overview page, you’ll see the original and variation automatically created for you.
  4. Click on the variation to make the changes you want.
  5. Manage other specifications like page targeting, audience targeting, schedule, traffic allocation, etc.
  6. Finally, run the experiment and analyze your results.

These steps are similar to those you’d find on most A/B testing tools.

Optimizely Over the Years

Founded in 2010, Optimizely was one of the first SaaS solutions to make web experimentation a popular internet marketing and digital experience practice.

It was started by ex-Googlers Dan Siroker and Pete Koomen. Several fundings later, it grew to a powerful tool with the number one popularity in the industry.

In 2020, it was acquired by Episerver, the web content management company now rebranded as “Optimizely”. And it, in turn, acquired the customer data platform, Zaius.

Over the years, they developed two primary SaaS products — Optimizely Web and Optimizely Full Stacks.

One of the notable things about Optimizely is how they’ve maintained mysterious pricing for so many years, making several price changes that have been tough to keep up with.

Has Optimizely Raised Prices? How Much Does Optimizely Cost? 

Optimizely pricing is not 100% clear to any one person. That’s because their prices are custom made for each customer’s needs and change a lot.

Not everyone loves this strategy, especially companies in their growth stage. It quickly becomes obvious that Optimizely’s business model focuses on companies with highly developed, serious optimization programs (“serious” here means big budgets).

Because of this, customers have to contact Optimizely’s sales teams to have their package tailored to their needs and get their quote.

But this hasn’t always been the case. Believe it or not, there was a time Optimizely had straightforward prices.

Optimizely initially cost as low as $17/month in 2011. That’s back when A/B testing as a conversion rate optimization tool was beginning to gain popularity. At this time, only the Platinum plan (enterprise users) had to contact sales for a custom price.

Then, about 3 years later, they moved to a 2-tier pricing structure — Starter and Enterprise. The Starter was free (and loved by small businesses) and Custom was, you guessed it, “contact sales for pricing”.

Then, another couple of years later, they started using a 3-tier pricing structure. Standard, Professional, and Premium — they all required users to contact Optimizely sales reps for the actual price. But you could still try Optimizely free for 30 days.

Word on the street was that the smallest plan during this time cost a minimum of $36,000 per year. And the highest yearly plan could whizz past $200,000. Even at that, according to ex-Optimizely customers, the functions were basic. And there is no grandfathering, which means your old plan’s price doesn’t apply when they hike the price. Note that this price goes higher according to your site’s traffic.

That same year, they removed the plans altogether and just featured a “Contact sales” button next to Optimizely features on their pricing page.

About 3 months later, the plans and free trial made a comeback. Optimizely Web had Standard, Business, and Enterprise, while Optimizely Full Stack only had Business and Enterprise. The actual cost was still a call away.

This all changed again that same year — no free trial, no plans.

Right now, no one is exactly sure of the price of a yearly plan with Optimizely (there are no monthly plans). But the latest number on Capterra is $50,000 with no free trial.

Optimizely’s Acquisition by Episerver

There was a lot of chatter in the CRO community about the acquisition of Optimizely by Episerver in October 2020.

Episerver was originally a content management company but officially rebranded to “Optimizely” in August 2021.

What does this mean for Optimizely and Optimizely users?

Some people think this is a bad look because Optimizely planned to go public, but that didn’t work out.

According to Optimizely, this doesn’t affect current contracts with customers. Except for some aesthetical changes, they aim to maintain business as usual.

But some changes customers will see are:

  • The fresh “Optimization-as-a-Service” product that combines Episerver’s content recommendations with Optimizely Web,
  • A new product roadmap will be revealed in the next few months, and
  • New hires to fuel this growth.

Some experts believe the desire to compete against Adobe in the Digital experience (DXP) industry drove this move by Episerver.

Episerver plans to do more than just provide personalized digital experiences and merge content, commerce, testing, and optimization. And Optimizely was the ideal candidate.

Optimizely has the capability and reputation but had taken a hit during COVID-19. They admitted laying off 15% of their staff as a result, and Episerver, having been acquired 2 years prior by Insight Venture Partners for $1.16 billion, had the capital.

When Should You Invest In Optimizely?

Using Optimizely poses some cost objections to a lot of CMOs and CROs. However, there are instances when it could be the ideal tool to use.

For example:

  • Enterprise budget

If you have the testing budget of enterprise marketing departments starting at $100,000 a year, then Optimizely is right within your reach. 

  • Mature optimization program

If your optimization program is still in its infancy, it may be difficult to justify the cost of using Optimizely. You should wait until your program is mature (that is, lots of experimentation ideas and the optimization team to run them).

Not only that, it makes sense to use this A/B testing software when you’ve proven the ROI of testing to C-suite execs.

Also on the topic of ROI, you should use Optimizely for A/B testing if the results will support actual decision making and produce insights for improving your products.

  • Ready for personalization

Personalization is one of the best things about Optimizely but it isn’t for everyone. The reason is that if you’ve not mastered A/B testing yet, it isn’t advisable to dive into personalization.

  • Website traffic is high enough

Are you getting over 250K unique visits per month? Then you’ll be able to implement the various tools Optimizely offers you to run a lot of experiments.

If these don’t sound like you, it’s best to check out other options for A/B testing.

Why Do Users Love Optimizely? 

  1. It’s easy to use, so anyone can build and run A/B testing or other experiments. No coding skills are required. The experiment results are easy to digest; you can easily see wins and losses.
  2. They allow easy personalization of web pages. Marketers use this to deliver custom digital experiences depending on different demographics.
  3. Users can change traffic allocation at any time — even while the test is running.
  4. Optimizely supports behavioral targeting which allows users to deliver custom experiences to certain visitor groups based on their behaviors.
  5. The Optimizely stats engine powers their statistical significance calculations and delivers results in a way that most people can easily interpret.
  6. They also provide learning resources. This helps improve user experience as users discover new ideas and get unstuck.
  7. They offer Optimizely Full Stack. It features experimentation for websites, apps, chatbots, APIs, smart devices, and feature flagging.

Now that you know everything there is to know about Optimizely, let’s look at its alternatives. But first, let’s see why people consider switching A/B testing tools and show how to make a rational comparison.

Why Do Testers Switch Tools?

Have you ever had a nasty breakup?  

It’s happened to all of us. Unfortunately, it also happens with the SaaS tools we use. 

Here are a few reasons:

  • Change in pricing. 
  • A decline in service. Or maybe the customer support lack from the beginning.
  • Buggy.
  • You outgrow the service. Or with many Optimizely customers, they realize the service is too big for them.
  • Poor support.

Sometimes it is not the tester at all who changes the tool, rather it is a decision made by the C-Suite, CMO, or lead CRO. There are several questions always lurking in the background regarding SaaS tools. Here are a few using A/B testing software as an example:

  • Is this A/B tool giving us the ROI we desire?
  • Is this tool supporting the optimization of our testing program?
  • Does the brand of the tool reflect the image of our brand in a positive light? 
  • Does this make the job of our team easier with better reporting and seamless use of the system?
  • Does the tool add to your Unique Selling Proposition?

It’s Not Always An Easy Road: What You Can Expect When You Switch A/B Testing Tools?

I wish I could say switching tools were always simple. It is not. 

In the best cases, it can be. 

Good, bad, or indifferent, you develop a relationship with the A/B testing tools you use. You get into a rhythm. You know how to navigate them; you understand exactly how to customize a test to your needs; you are on a first-name basis with the customer support team, and the company even sends you cool swag. 

It is easy to become invested in the tools you use. And by definition, the nature of change (even change for the better) comes with friction.  

However, knowing the potential roadblocks and planning for them can make your transition easier. So here are a few to consider:

  • New Learning Curve: Onboarding
    Once you commit to making a switch, don’t wait until you completely change A/B testing platforms to learn the new tool. Flirt with it. Watch videos. See how your peers are using the tool for success.

    Prepping and creating a clear learning path can help reduce the number of eaten billable hours during set-up.

  • Replicating Integrations
    More than likely you are going to want to replicate the same integrations you used with your other A/B testing solutions.
  • New, Different, or Unavailable Features
    Sometimes improvements affect the product negatively. Maybe it is not a “bad” change, however, the new features may inadvertently affect your usage.  

This doesn’t have to be a bumpy road for you. With the right methods, you can make your switch as smooth as possible.

Let’s show you how.

How to Choose an Optimizely Alternative 

Reasons people choose one experimentation platform over another are dynamic and custom to the needs, cultures, and goals of your company. 

Here are a few questions you can ask yourself: 

  • What do you need in an A/B testing tool?
  • Head-to-head, what tool offers the most value? Can you calculate the ROI of one A/B testing tool against another? 
  • What company will give your team the support they need to become better CROs, developers, and help you cultivate a better culture of experimentation?
  • What are must-have features, what are optional features? You can actually break this down into a table:
Determine your must-have and wish list features to compare alternative A/B testing solutions.
Determine your must-have and wish list features to compare alternative
A/B testing solutions.

Many of these features come standard in most representable A/B testing software. 

However, features like Flicker Reduction and Hypothesis generation tools are gold. They alleviate two common issues that crop up when A/B Testing: 

  1. The problem of flicker, which is when the original version is shown to visitors before the variation. Flicker sabotages your results and can frustrate your traffic. And, 
  2. Standardizing your ability to create credible hypotheses that convert to big learning and lifts.

The Idea Library is one of Optimizely’s most popular features. It’s a cure for blank page syndrome by providing users with ideas and suggestions. However, as popular as this feature is, it can be counterproductive, pulling your team away from creating based on internal data and goals, rather they model generic templates.

Now you are armed with a framework to compare, here are 8 best Optimizely alternatives to consider.
