<\/a><\/figure>\n\n\n\nSee the impact of your TMS on YOUR site with Chrome Developer Tools<\/h2>\n\n\n\n
If you want to get a quick sense of the impact marTech has on your<\/em> site, there is an easy way to do it using the Chrome Developer console. I find the easiest way to get to the Dev Console is to right-click anywhere on a page and choose “inspect” (you can also do Ctrl+Shift+J on Windows or Ctrl+Option+J on a Mac). Once in there, go to the network tab (#1) and find your main TMS container file. You can use a filter (#2) to get to it quickly: adobedtm.com<\/em> or launch<\/em> for Launch, googletagmanager.com<\/em> or gtm<\/em> for GTM, or utag<\/em> for Tealium. Right click on the first file that matches that filter (#3), and select “Block Request URL” (#4):<\/p>\n\n\n\n This essentially gives you an “ON\/OFF” switch for your TMS:<\/p>\n\n\n\n You can load any page on your site with your TMS “on”, as it is for all your users, then turn your TMS “off” and see the difference in load times and amount of files and weight on your site. The “DOMContentLoaded” and “Load” numbers at the bottom of the network window are good ones to watch, since they show the amount of time for the main structure of your site to be built, and the time for images and other content to load.<\/p>\n\n\n\n Do make sure you’re comparing apples to apples- either use a fresh incognito window for each load, or click the “Disable Cache” checkbox in the network tab (#5 in the graphic above).<\/p>\n\n\n\n For example, with the TMS in place, this particular site I tested took 3.5 seconds to load, and had 54 files (“requests”) with a total weight of 3.2 MB. (I tend to ignore the “KB transferred” and “Finish” numbers for reasons not worth going into).<\/p>\n\n\n\n After I “blocked” the TMS, those DOMContentLoaded and Load times went down considerably<\/em>:<\/p>\n\n\n\n This isn’t a perfect science- every time a user loads a page they’ll get slightly different times depending on device, bandwidth, server response times, and caching- but it can give you a quick sense of how much your marTech and analytics scripts have on your site. If you want to take it a step further, you can use this “Request Blocking” trick while running a lighthouse test directly in your dev console:<\/p>\n\n\n\n If you want to dig deeper, I’ve developed an Excel template<\/a> that uses webpagetest.org<\/a> to export then analyze the domains that load resources on your site:<\/p>\n\n\n\n Deeper instructions are in the template<\/a> itself, but at a high level: run a webpagetest.org<\/a> scan of a page on your site- for instance, I ran a scan<\/a> on marketingAnalyticsSummit.com<\/a>. Once the scan has run, grab the URL and paste it in to cell B1, just for safekeeping (you can always refer back to it later). The “good stuff” is on the Domain tab, but if you’re interesting in overall metrics on the main page, you can throw this script in your developer console:<\/p>\n\n\n\n Then paste into cell A4 in the template (it’s bright yellow) to fill out this handy little table:<\/p>\n\n\n\n Next go to the domains portion of the scan:<\/p>\n\n\n\n In general, you can use the process of elimination to figure out what is from a marTech vendor… in most cases, if it isn’t a domain you own, it’s marTech (not always, but… often enough). Figuring out which<\/em> marTech vendor can be a bit trickier. I mean, www.linkedin.com is pretty obvious, but LinkedIn also fires resources from licdn.com. <\/p>\n\n\n\n Over time, I’ve collected a mapping of domains to vendors<\/a> that we’re making publicly available. It will never going to be comprehensive (the list of 9900+ marTech vendors<\/a> is ever growing and changing) but it can at least serve as a starting point. If you have changes or additions, you can throw them on the un-curated (and publicly editable) version<\/a>. Anyway, once you are on the Domains Breakdown part of your scan results, you can put this code into the developer console to copy the table on the right to your clipboard:<\/p>\n\n\n\n Then paste the result into cell A12 of the excel template (it’s red), which will fill out the table and allow it to check if domains match our list of known domain\/vendor mappings<\/a>, then summarize what it finds:<\/p>\n\n\n\n For instance, here we find that marketinganalyticssummit.com’s home page weight is 26% marTech (and 8% TMS). It’s a very light site to begin with, so 26% of not much is…. not much. But it’s interesting to see how much is going on behind the scenes, even on “light” pages.<\/p>\n\n\n\n Now that you’ve established a high-level view of marTech’s impact on your site, you may want to dive deeper and do a tag audit… I’ve got tips and tricks for how<\/a>!<\/p>\n","protected":false},"excerpt":{"rendered":" Folks often take for granted that they “must” have analytics and martech tracking and tools on their site.
