    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.

    This is suited to plan for keywords in a single market, but it struggles when you need to consolidate several markets. It is well-suited to discover new keywords directly related to the ones being used currently to expand the content the company is creating to get better results.

    • Great visuals for keyword position tracking, love that you can see the page that is ranking
    • Enjoyed the auto-generated reporting feature (specifically in the context of keyword position tracking)
    • Shows many different and useful views for competitive research
    • Great templated keyword research tools for those who are not as hands-on with SEO
    • I LOVE the Keyword Magic Tool for honing in on longtail, high-opportunity keywords

    Cons
    Optimizely
    • 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.

    • Extra seats can be expensive, as [an] agency with multiple team members this can be frustrating
    • Backlink data is not great, misses out a lot of backlinks (better off using a specialist backlink tool like Link research tools LRT)
    • Tracking multiple keywords, across multiple clients can be costly

    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
    Optimizely
    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 interface is a little less intuitive than it could be. The data is often available but filtering and manipulating the data can be a little difficult at times. Expanded comparisons would be helpful since most of the time seeing more than a few competitors at a time allows for a better sense of how to forecast.

    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.

    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 have used both Ahrefs and Semrush extensively at our agency and Semrush remains the tool of choice. We find that Semrush has the largest selection of tools & features to use, with the highest accuracy, and provides top-tier analysis recommendations. It's really is the ultimate all-in-one tool when comparing other performance measurement tools in the digital marketing space.

    • 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.
