Where This Fits
PageSpeed is a Monitor tool. Use it to establish technical performance baselines and identify pages where slow load times may be affecting AI engine access and indexing.
What you see in the product

- Historical run comparison to track changes
Plan behaviour
Plan behaviour
- Pro — PageSpeed diagnostics available for tracked URLs
- Agency — Full access across all sites with reporting support
When to Use It
When to Use It
- You suspect slow page speed is affecting how AI engines access or cache your content.
- You want to establish a performance baseline before making technical changes.
- You want to verify that a deployment improved Core Web Vitals on specific URLs.
Common Pitfalls
- Lab data and field data can differ significantly — don't treat them as interchangeable.
- A single PageSpeed run is a snapshot. Compare across runs to understand trends.
- Improving performance scores does not guarantee improved AI citation — address both separately.
Example
Example
You use "PageSpeed" to establish current visibility and identify where results are weaker than expected. The output gives you a baseline you can review again after making changes.
What it looks like
