All about coding methods to obtain the highest possible score on Blogger with GTMetrix (Pagespeed and YSlow).

The primary blog of interest for this experiment and optimization is (located here).

UPDATED 5/10/17 On the evening of 5/9/2017 while testing posts yet another set of errors began manifesting clearly due to a blogger technician configuring the system to override the customized template code I had created which removed 100% of Blogger's CSS. This new and unwanted forceful insertion of blogger's external (and unnecessary CSS) has also misconfigured our blog's layout at top and bottom. Specifically, these two NEW inserted files are the culprit:

I'm sure that a technician is getting a chuckle out of this.

1) <link type='text/css' rel=stylesheet href='https://www.blogger.com/static/v1/widgets/1691512649-css_bundle_v2.css'/>

2) <link href='https://www.blogger.com/dyn-css/authorization.css?targetBlogID=28300773&zx=71ea89df-0fe4-4b55-bbc4-0115c3e35696' rel=stylesheet />

After many months of customizing our blog, which required thousands of hours of study and work to achieve 100% Pagespeed and 99% YSlow, only to have this high score sabotaged I no longer feel blogger is the right place for our blog since I value speed, quality and visitor experience. We will still use blogger for composition of posts, but transfer them to a private server. I have also disposed of any and all high bandwidth draining tracking devices.

On last count, two external CSS files are being injected into the blogger template, reducing Pagespeed scores from 100% to 99%... YSlow has declined to 96%, in spite of customized code which had removed those external css generated errors. Both injected css files are absolutely unnecessary. 100% Pagespeed/99% YSlow is what our blog was getting prior to this... unnecessary configuration.
