    Answers to common questions.

    Do I need to install anything?

    No. Everything can be controlled from your dashboard.

    How often can I receive alerts?

    We scan your monitored URLs hourly, daily or weekly. If your score is good you won't hear from us. However, if it's slow you'll receive an email and slack message if requested. This can be set in the backend.

    Does it check mobile and desktop scores?

    Yes, we test every URL on mobile and desktop.

    What metrics do you measure?

    The primary metric we focus on and what we based our alerts around is the score from 1 to 100 returned by the PageSpeed Insights API. For additional insight, we also show Lighthouse and Web Vitals scores Largest Contentful Paint(LCP) and First Input Delay(FID) and Cumulative Layout Shift(CLS)

    How is the score calculated?

    Each URL is checked 3 times on mobile and 3 times on desktop. The final score is the average of the 3 scans.

    Does it use Lighthouse Data?

    Yes, PageSpeed Plus is powered by version 6 of the PageSpeed Insights API which uses lab and field data from Lighthouse and allows us to return all data points available.

    What is an acceptable score?

    Google looks favourably on sites that score 90 and above but we allow you to set your own thresholds for alerts.

    Can I export the data?

    Yes. Data is automatically exported to a google sheet. From there it can be ingested into other tools.

    What is the difference between Monitored & Full Site Scans?

    Monitored URLs are in depth scans that measure a wide range of things multiple times to give an average score that is more representative of real world behaviour. Full Site Scans measure less things and only take one reading. See a full comparison in our docs.

    How often can I run a full site scan?

    You have the option of daily, weekly(at the weekend) and on demand scans. We recommend a weekly scan unless you are releasing major changes that could impact your score.

    What is

    PageSpeedPlus monitors Google PageSpeed Insights scores for any website and sends alerts when important pages are slow. You have the ability to highlight which pages should be monitored from the dashboard.

    PageSpeedPlus also runs full site scans so every page on your website is tested on both mobile and desktop. Users receive an email with an average score when a full site scan completes so you can get an overall view of what you score is and if you need to look deeper at our reports. background

    PageSpeed insights is a fantastic service for people who operate small websites that don't change very often. You can paste a URL and receive a detailed report in 20 seconds about how that page performs in the eyes of Google.

    However, there is no way to automate this and you have to return to the PageSpeed Insights UI and repeat the process time after time. Very frustrating.

    Additionally, if you have more than a handful of pages it becomes impossible to test them all so most people fall back to testing the homepage and some other URLs they feel are important.

    Having built some websites that required good Pagespeed Insights scores, we got tired of these repetitive tasks getting in the way of more rewarding development work and felt they could be solved by a well designed tool with automation. From that, was formed.
