    AsyncJS adds defer='defer' to the <script nodes with a src attribute, I had a look and this happens both on your homepage and on /bale-home so from AsyncJS all is OK. The fact that GTmetrix still lists some JS as render-blocking is not somethings AsyncJS can help with I’m afraid.

    hi

    so your plugin doesn’t work for external scripts like googles’?

    Well, the defer='defer' code that AsyncJS injects are present, so all JS linked in the HTML should effectively be deferred. I *guess* this could be a gtmetrix mistake, does Google PageSpeed Insights lists those JS-files as render-blocking?

    hi
    i have not checked with Google PageSpeed.
    but you did not answer my question directly.

    AsyncJS adds defer (or async) flags to all JS files linked in your HTML (including Google’s), so it _should_ work, which is why I suspect these are false positives from GTMetrix and why I propose to test in GPSI which in my experience has a better view on render-blocking issues 🙂
