Testing & Diagnostics
You can use the following Google tool for web speed diagnostics
As a benchmark, here are some screenshots of Gray Line Austin's website (92% score on mobile, 97% score on desktop). This page is probably the lightest one of the Gray Line licensee sites we know of - no 3rd party plugins, no facebook pixel, no tracking, no extra video / images / footer modifications etc. Purely the template as we've designed it, a light fast homepage with no extra weight added.
You may have happened to run diagnostics either after a manual cache clear or an automatic cache clear of the website. In this case, your site speed will be significantly lower. It is good to visit the pages you want to speed test prior to testing to make sure the cache has been rebuilt.
Often a major issue is the improper sizing of images. If Google recommends properly sizing the extra images you've added to the page, please see this article for help
CloudFlare can offer extra speed gains
It is possible to have a fast, light website. What will you sacrifice in terms of your page speed, for content / analysis / 3rd party functionality gain?
