Monitor weekly PageSpeed scores with Apify, Google Sheets, and Slack

Description

Quick overview
Every Monday this workflow audits your list of pages with Google PageSpeed Insights (via the Bulk PageSpeed Insights & Core Web Vitals Checker Apify Actor), logs one row per page to Google Sheets, and posts to Slack only when a page drops below your threshold or fails Core Web Vitals.

How it works
Schedule Trigger runs weekly (Monday 7am; change it to any interval).
Set node holds your URL list and minimum performance score.
Apify node runs the pewterdesk Bulk PageSpeed Insights & Core Web Vitals Checker Actor and waits for the results (cost cap: $1 per run).
Code node flattens results into clean rows with performance and SEO score, lab LCP and CLS, real-user (CrUX) LCP and INP, Core Web Vitals pass/fail and the biggest fix Lighthouse suggests, and flags pages that need attention.
Google Sheets appends every row to a tab named PageSpeed log.
A second Code node builds one Slack message only if something is slow, and the Slack node posts it.

Setup
Create a free Apify account and add your API token as an Apify credential.
Optional but recommended: add a free Google PageSpeed Insights API key to the Actor input.
Create a Google Sheet with a tab named PageSpeed log and connect your Google Sheets credential.
Pick a Slack channel and connect Slack (or delete the Slack node if you only want the sheet log).
Edit your URL list and minimum performance score in the Set node.

Requirements
Apify account (free) and API token

Customization
Audit desktop too: add 'desktop' to strategies in the Apify node.
Track accessibility or best practices: add them to categories.
Swap Slack for email, Discord or Teams.

Additional info
Who is this for? Site owners, SEO folks, agencies and developers who want to know when a page gets slow, without checking PageSpeed Insights by hand.
