7 Chrome Extensions for CRO

Chrome Extensions are awesome. They're incredibly useful and when put to good use can really show a website optimiser what's what and who's who; they help with the day to day job.

1. DataSlayer

Debug and test tag management (Google Tag Manager, Tealium) and analytics implementations. Dataslayer adds a panel to Chrome Developer Tools that monitors tag management data layers and displays changes in an easy-to-read, user-friendly format.

From an optimisation perspective, this allows us as conversion optimisers to to see what tags fire and when. This data can then be corroborated with data in Analytics to determine what events relate to what action; if, indeed, any events fire. It also allows us to view the data layer with actions to ensure configuration of, say, enhanced ecommerce.

2. Tag Assistant

Tag Assistant helps to troubleshoot installation of various Google tags including Google Analytics, Google Tag Manager and more.

Tag Assistant helps you verify that you have installed various Google tags correctly on your page. Just navigate to any page and Tag Assistant will tell you which tags are present, report any errors we find and suggest improvements that can be made to your implementation. Most Google tags are checked including Google Analytics, Adwords Conversion Tracking, Google Tag Manager and more.

From an optimisation perspective, this allows us, if we have access to the client's Analytic's account, to see exactly how our movements interact with Google Analytics. I recommend setting your recordings and clicking on a PPC campaign and making a payment on the site. Are there duplicate sessions? Is the campaign parameter carried through to the website? Are the correct transaction totals carried through the data layer? World of use this little tool.

3. Conversion.com's Optimizely Checker

This extension allows you to learn information about Optimizely on a given page. You can view Optimizely events, open all the variations of a certain experiment in different tabs and see the current Optimizely Revision ID amongst much more.

The best thing? Go to a website that uses Optimizely and take a sneeky peek at their experiments that they're currently running. For example, take a look at the current experiments running on Teletext Holidays.

4. Statistical Test for Google Analytics

This extension enhances Google Analytics by providing implicit statistical evaluation of data.

One very useful feature of Google Analytics is the comparison of time-frames for a given metric. We can compare number of sessions, bounce rate, E-commerce transactions, AdWords cost, etc. between adjacent weeks, months, or years. One shortcoming in this comparison feature, is that the percentage change calculated by Google for these metrics is not qualified. This extension addresses this shortcoming by providing a one-click evaluation of the current time-frame in your Google Analytics.

A really useful tool to see if the data you're comparing against is actually statistically significant.

5. UX Check

UX Check makes heuristic evaluations quick and easy. The extension will open up Nielsen's Ten Heuristics in a side pane next to your website. When you click on an element that doesn't comply with a heuristic, you can add notes, and a screenshot will be saved. At the end, you can export everything to a docx so that you can share them with your team.

This is really useful for an initial collaborative heuristic review between team members. Highly recommended for an initial review of a website, followed by an export of subjective thoughts.

6. Screencastify

Screencastify is a simple video screen capture software for Chrome.

Screencastify is a simple video screen capture software (aka. screencast recorder) for Chrome. It is able to record all screen activity inside a tab, including audio. Just press record and the content of your tab is recorded. So you can easily create a screencast for video tutorials, record presentations etc. It also supports desktop capturing, allowing you to record anything on your screen (not just tabs).

There's always the need to capture video within a conversion optimiser's job. Whether it's noticing a bug within a client's website or recording a user journey and your / other thoughts through said journey, video or screencapture is always useful (and needed!)

7. Google Analytics Debugger

Prints useful information to the JavaScript console by enabling the debug version of the Google Analytics Javascript.

This extension loads the debug version of the Google Analytics Javascript for all sites you browse using Google Chrome. It prints useful information to the Javascript console. These messages include error messages and warnings which can tell you when your analytics tracking code is set up incorrectly. In addition, it provides a detailed breakdown of each tracking beacon sent to Google Analytics.

This is how we start almost every single project by using this handy little extension, ensuring everything looks the way it should look.

There are a host more of Chrome extensions we use as well. Here's another blog post that could be of interest who had a few of the same tools we labelled above http://trevorfox.com/2015/01/7-chrome-extensions-for-testing

Are there any extensions or tools not mentioned that you can't live without for AB testing and experimentation?
