Here is my clear and direct critique to the probably most dangerous recommendation given by a Google employee Gary Illyes to Webmasters since I started doing "Google-stuff" in 2003.

And the even more dangerous transcription in The SEMPost by Jennifer Slegg although Jen has been around for a long time, too... (probably an editor's mistake).
This post is NOT about "Best Practices for 301 redirects", but a sure way to get your website's traffic and rankings into trouble.
*** Please do NOT follow Gary's advice ***
or promote this as the latest and greatest "website speed trick".
Don't remove your redirects!
The idea to delete redirects as soon as Google crawled them is NOT GOOD
This topic is very on time with our current hot topic redirects and rel-canonicals.
We also just launched a new "Link Redirect Trace" add-on for Chrome and Firefox to help with these things.
