Biggest opportunity: Add “execution”, “improve” and “script” to your wp.org tags. You rank #7, #8 and #9 for them without listing them, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 2 listed these are the slots worth spending.

of downloads still active
At least 30K of 320.9K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,766 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 2 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

Good and efficient plugin. 5 stars
Read on wp.org ↗ - ★★★★★ Tom Bush3.8y ago
Sooo easy to set up and a great way to deal with heavy JS from advertising etc. Really simple but brilliant approach to defer until user input. Pagespeed Insights overall score went from 58/70 to 99/100 for mobile & desktop respectively without any other changes (appreciate these values fluctuate anyway but that’s a significant jump even +/- a few points on the final values).
