GA Checker 
Check your entire site for missing Google Analytics or Google AdWords code with one click
About GA Checker
GA Checker spiders your site, much like a search engine, and identifies which pages contain Google Analytics and/or Google AdWords tags and which ones do not. The tool currently checks for the presence of the following:
- Google Analytics (ga.js)
- Google Analytics Remarketing (dc.js)
- Google Universal Analytics (analytics.js)
- Google Analytics Global Site Tag (gtag.js)
- Google Analytics Experiments (ga_exp.js)
- Google Tag Manager (gtm.js)
- Google AdWords Conversion (conversion.js)
- Google AdWords Phone Conversion (loader.js)
- Google AdWords Remarketing (conversion.js)
- Google AdWords Dynamic Remarketing (conversion.js)
- Google Optimize
- Google Surveys
- Google DoubleClick
The tool will verify the presence of a UA number and track pageview call (where applicable), and the presence of the javascript file that's listed above. Please note that this doesn't guarantee your code is error-free, although if everything seems to be tracking normally then it can generally be assumed the code on your pages is correct. I would still recommend spot-checking your code on a few pages with Google Tag Assistant just to be safe.
Why is the progress bar jumping all over the place?
The tool doesn't know how many pages there are on the domain when it starts. It finds new pages by following links, so as it discovers new links the % of links crawled changes. And I suck at coding.
Why would I need a tool like this?
So you don't embarass yourself by reporting on inaccurate data. Make sure all your GA tags are in place so that you get the cleanest data possible.
My site has more than 10000 pages. Will GA Checker still crawl the entire site?
Nope, not the whole site, although it will give you the first 10,000 pages that were crawled. If you want to crawl a larger site, you'll have to get in touch with me (maciej DOT lewinski AT gmail DOT com, or @lewwwin on Twitter).
What is this tool looking for exactly? If GA Checker says the tag is there, can I assume it's working?
If GA Checker found your tag, chances are the tag is installed correctly but this isn't always the case. The tool looks for the presence of two key lines of every GA tracking code, the UA ID and a track pageview line. Generally if your tag has these two things, you should be fine, but I would spot check a few pages just in case. The Tag Assistant plugin for Chrome is a good way to do this.
