Very useful and relatively easy **Rating:** 4.5/5.0 stars **Reviewed by:** Ben B. | Director of Marketing, Information Technology and Services, Mid-Market (51-1000 emp.) **Reviewed Date:** July 26, 2013 **What do you like best about Optimizely Web Experimentation?** Really awesome tool. Install the script on your site and test away. No altering the script on your site... same snippet of code is used on every page, so an include works excellently. The editor is slick (though it does struggle with arranging content at times, which is when we just open up the html and do it directly). All around a great tool that has helped us optimize our pages. **What do you dislike about Optimizely Web Experimentation?** We're on the $80/month plan, which has just enough credits that we can do testing of interior pages (that don't get much traffic). We ran a test on the homepage and it used our monthly quota in about a week. Sadly, they don't have a mid-tier package. Instead you go from $80/month up to $400/month if you want a quota to do a lot of testing. **Recommendations to others considering Optimizely Web Experimentation:** Do it! It's a great place to start. Once you're a testing wizard you can move up to a bigger, more expensive tool. ### 7.
