Is keep alive enabled on your web server? Use our SEO tool to check the Persistent Connection status of your website. Check multiple URLs with Bulk mode. 

It’s no secret that page speed is a Google ranking factor – when you look at your website’s performance waterfall chart using one of the page speed testing tools, you can see that when you get a site from a server with Connection: close, every resource is loaded over a new connection (the orange bar in the waterfall chart), which adds more time to your page load time.
