Optimizely - More expensive and responsive functionality is less reliable. The WYSIWYG editor is also a little more difficult to use and many times requires custom coding for desired experience. The A/B testing tools are a little more sophisticated, but Instapage is sufficient …

We wanted one tool, that was easy for marketers and developers to use and would allow us to remain organized. Neither Of the other products allowed for this as seamlessly as Optimizely.
Chose Optimizely Web Experimentation
Out of all of the split testing tools I have used, Optimizely has displayed the best performance and engineering surperiority. While it is expensive, for sites that get lots of traffic & have critical performance requirements, Optimizely is honestly the only split testing …
Chose Optimizely Web Experimentation
Honestly Optimizely is so much better then everything else, the only one that compares is Google Optimize, but it wasn't in this list. I don't think the others are worth while, as the data you get back and the responsiveness/smartness of the tests are not near as good as what …
Chose Optimizely Web Experimentation
Optimizely is a great tool for A/B testing landing pages, I'd recommend it to anyone who doesn't have a built-in A/B test workflow. I haven't come across a worthy competitor that does what Optimizely does. Their software is also much more robust than landing page platforms that …

airSlate, Inc
Well-suited for simple landing pages which don't have any complex functionality. Great for creating landing pages for lead generation campaigns - as it comes with tons of excellent templates and a variety of forms. Not great for pages that contain a lot of information and can potentially be very long. We found that Instapage is not a great fit for building pages that need to be updated frequently, like a blog page.

I think it can serve the whole spectrum of experiences from people who are just getting used to web experimentation. It's really easy to pick up and use. If you're more experienced then it works well because it just gets out of the way and lets you really focus on the experimentation side of things. So yeah, strongly recommend. I think it is well suited both to small businesses and large enterprises as well. I think it's got a really low barrier to entry. It's very easy to integrate on your website and get results quickly. Likewise, if you are a big business, it's incrementally adoptable, so you can start out with one component of optimizing and you can build there and start to build in things like data CMS to augment experimentation as well. So it's got a really strong a pathway to grow your MarTech platform if you're a small company or a big company.

Pros
airSlate, Inc
  • Instapage makes it easy to frame out a landing page really quickly. They provide template blocks for various components of a landing page (header, features, testimonials, etc.) that you can easily modify for your own needs. Other tools provide whole-page templates, but I much prefer the section-level templating. It's more convenient to assemble a page this way and add the details on top of that versus taking a finished template and peeling away design and functional elements to get what I want.
  • Instapage's mobile auto-resizer works better than other platforms I've used. I found that I had many fewer adjustments on their auto-resizing of the full page than I've experienced with other tools. I still had to work with text size a bit, but they generally did a better job of ordering elements for mobile the way I would want and maintain proportionality of page elements better.
  • Instapage has a lot of integrations that marketers will love. I don't know if they particularly stand out in this respect, but this is a particularly important aspect of their tool that most marketers will care about.

  • The Platform contains drag-and-drop editor options for creating variations, which ease the A/B tests process, as it does not require any coding or development resources.
  • Establishing it is so simple that even a non-technical person can do it perfectly.
  • It provides real-time results and analytics with robust dashboard access through which you can quickly analyze how different variations perform. With this, your team can easily make data-driven decisions Fastly.

Cons
airSlate, Inc
  • There are only a couple of minor issues that I dislike. One is offering a Drupal community-approved update to their module. We are using a slightly older version of Drupal and it appears they don't have plans to offer a Drupal-approved update to their module for that version.
  • There are also random bugs when trying to format text. For example, sometimes a sans serif font appears as a serif and doesn't seem to want to change.
  • If you work with a template and some code, it can be challenging to edit the default coding.
  • The built-in forms can be a bit limiting.
  • The program will try to automatically reformat for mobile, but it may not always be exactly the way you want it to look, so there is a bit of redesigning required when going to mobile.

  • JavaScript is hard to implement sometimes especially for JQuery elements
  • ROI reporting should be part of the overall experimentation reporting
  • CMP integration: where we can easily show status of test on the HPT request
  • CMS integration
  • More widgets like social proof banners, etc.

I rated this question because at this stage, Optimizely does most everything we need so I don't foresee a need to migrate to a new tool. We have the infrastructure already in place and it is a sizeable lift to pivot to another tool with no guarantee that it will work as good or even better than Optimizely

Usability

I've tried all of the other landing page services on the market, and this is literally the easiest to use. I am not a designer or software developer, just a simple guy and if I can learn how to use it, anyone can. That's what won me over. Their support and pre-made templates are awesome, but the usability is what I love!

Optimizely Web Experimentation's visual editor is handy for non-technical or quick iterative testing. When it comes to content changes it's as easy as going into wordpress, clicking around, and then seeing your changes live--what you see is what you get. The preview and approval process for sharing built experiments is also handy for sharing experiments across teams for QA purposes or otherwise.

The tool itself is not very difficult to use so training was not very useful in my opinion. It did not also account for success events more complex than a click (which my company being ecommerce is looking to examine more than a mere click).

In retrospect: - I think I should have stressed more demo's / workshopping with the Optimizely team at the start. I felt too confident during demo stages, and when came time to actually start, I was a bit lost. (The answer is likely I should have had them on-hand for our first install.. they offered but I thought I was OK.) - Really getting an understanding / asking them prior to install of how to make it really work for checkout pages / one that uses dynamic content or user interaction to determine what the UI does. Could have saved some time by addressing this at the beginning, as some things we needed to create on our site for Optimizely to "use" as a trigger for the variation test. - Having a number of planned/hoped-for tests already in-hand before working with Optimizely team. Sharing those thoughts with them would likely have started conversations on additional things we needed to do to make them work (rather than figuring that out during the actual builds). Since I had development time available, I could have added more things to the baseline installation since my developers were already "looking under the hood" of the site.

HubSpot was terrible because it required a lot of coding experience if you wanted to work outside the given 4-5 templates. If you wanted a new template built, or to rebrand existing templates, they charged you. Very inflexible program and was very challenged by it. Our main website was built using WordPress, which is great for building webpages, but more difficult to build a landing page without the distraction of the top navigation menu. Instapage literally answered all the problems we were seeking to address: simplicity, customization, ease of use.

The ability to do A/B testing in Optimizely along with the associated statistical modelling and audience segmentation means it is a much better solution than using something like Google Analytics were a lot more effort is required to identify and isolate the specific data you need to confidently make changes

We can use it flexibly across lines of business and have it in use across two departments. We have different use cases and slightly different outcomes, but can unify our results based on impact to the bottom line. Finally, we can generate value from anywhere in the org for any stakeholders as needed.

Return on Investment
airSlate, Inc
  • We've not had much of a conversion rate on some of our landing pages -- but this could be because we are relatively green with the marketing side of things and forget to send people to it. It's not easy for people to find on their own -- so I highly recommend you use some of the "hidden" SEO tools to increase the ROI. Without it, you're not going to be happy with your investment.

  • We're able to share definitive annualized revenue projections with our team, showing what would happen if we put a test into Production
  • Showing the results of a test on a new page or feature prior to full implementation on a site saves developer time (if a test proves the new element doesn't deliver a significant improvement.
  • Making a change via the WYSIWYG interface allows us to see multiple changes without developer intervention.
