Identify Slow Pages with Google Pagespeed Insights for WordPress

There are many well-documented benefits of having a fast-loading website including higher rankings in the search engines, better goal conversion rates and more return visits. Conversely, a website that loads slowly can cost you visitors and revenue due to diminished rank in search engine results pages and a higher rate of abandonment from those visitors who do find their way to your site.

Thankfully there are many ways you can speed up your WordPress website, from choosing a fast loading theme, through to migrating to a high performance web host. However even if you’ve done all you can to decrease the load times for your site, it’s still important that you keep an eye on this vital metric.

Installing additional plugins, posting new content, or tweaking the design of your site, can all have an impact on your page load times. However, by regularly monitoring your site speed, you can quickly see if and when any problems arise and then fix them to resolve the issue.
