Boost Your Site!

By Phillip Gordon (phillipmules) on September 13, 2025

Jetpack Boost offers a promising way to enhance your WordPress site's speed and overall performance. While results may differ depending on your setup, the most reliable way to gauge its impact is to install it and run your own tests. That way, you can determine whether it aligns with your site's specific needs and goals. Highly recommended!

Don't trust the stats

By tgrblogger on September 2, 2025

The load stats are all over the place and does not reflect what SEMrush and pagespeed insights show. I feel that I cannot trust this plugin.

Why does it revert after a few hours?

By Syka Daze (sykadaze) on September 1, 2025

I went through this process of speeding up my site, and briefly it was all well on my website. Then I looked at the dashboard a few hours later and it had reverted. I find Wordpress horribly slow, but I am pleased that it is a free product. However it seems to be set up tp be inadequate unless you pay multiple fees. Is that a fact or not?

Making my life easier

I'm not a professional webmaster (heck, I don't know if they're even called that anymore) so I appreciate any plugin that makes my site load faster for my visitors!
