Frequently Asked Questions

Do Unlimited On-Demand Tests really mean unlimited?

Yes, you can run as many tests as you need. But “unlimited” comes with a Fair Use Policy to make sure the platform stays reliable for everyone.

While no hard caps are enforced, GTmetrix reserves the right to restrict or suspend accounts where usage is deemed excessive, abusive, or outside the intended purpose of performance monitoring.

Examples of misuse include (but are not limited to):

• Running continuous automated scripts to generate artificial load
• Performing bulk stress tests or scraping activity
• Consistently generating volumes far above normal customer usage levels

We may adjust or suspend access if such activity threatens platform stability or negatively impacts other users.

What is a Monitored Slot?

Each URL paired with Analysis Options (location, device, connection speed, etc.) having monitoring enabled (hourly, daily, etc) would consume one monitored slot.

For example, monitoring the following:

• https://example.com (Seattle, WA, USA, Chrome, Unthrottled)
• https://example.com (San Antonio, TX, USA, Simulated iPhone 6/6S/7/8, LTE)
• https://example.com (London, UK, Chrome @ 1366x768, Broadband Fast)
• https://anotherdomain.com (San Antonio, USA, Chrome @ 1366x768, Broadband Fast)

Would require 4 monitored slots.

Take an inventory of the number of URLs and scenarios you intend to monitor, and select a PRO plan that suits your needs.

How many Monitored Slots do I need?

The number of Monitored Slots needed will depend on your visitors and overall performance goals.

Small websites may only need to monitor a few pages, whereas larger websites may have more key pages that users visit frequently, are primary entry points, or part of a campaign.

Read our article on determining how many monitored slots you may need.

At what frequency should I monitor my pages?

How often GTmetrix tests when monitoring your pages depends on how critical the performance of your website is to you and/or your visitors.

Whether performance is mission critical, or if you only need to keep an eye on performance from time to time, there's a frequency that makes sense for you.

Read our article on how to determine a monitoring frequency.

What is an On-Demand Test?

A test run from within your GTmetrix Dashboard, or re-tests done from a GTmetrix Report are considered On-Demand tests.

After you reach your On-Demand test limit, subsequent tests will be rate limited until your test limit resets.

Each PRO plan has a number of On-Demand tests allocated to it, be sure to select a plan that would match the number of On-Demand tests you expect to be doing.

Reports generated from monitoring or the API are not considered On-Demand tests and will not deduct from your amount.

What is the GTmetrix MCP?

The Model Context Protocol (MCP) is an open standard that gives AI models a direct line to external data and developer tools.

The GTmetrix MCP server uses this standard to bring our powerful web performance engine straight into your AI development tools and LLM clients.

Now your AI assistant can natively run tests, audit Core Web Vitals, and fetch real-time page speed insights right inside your terminal or workspace chat.

Will I be charged every month/year if I subscribe to GTmetrix PRO?

Yes - GTmetrix PRO is a subscription service. You'll be charged the cost of your plan at the end of your billing term (every month or year depending on what you've selected).

If you do not wish to continue your subscription, you can cancel your subscription and we won't charge you on the next billing cycle.

What payment options does GTmetrix accept?

We accept Visa, Mastercard, American Express, Discover, Diners Club, JCB, and PayPal.

We can also accept Bank/Wire Transfers and Purchase Orders, but as we manually process these payments, we require a minimum spend commitment and a yearly term commitment. Please contact us to learn more.

Can I switch my plan from monthly to yearly? (or vice versa)

Yes, you can switch from a monthly to a yearly billing cycle at any time. However, if you're switching from a yearly to a monthly billing cycle, then the change will happen after your existing yearly billing cycle has completed.

What if I want to upgrade or downgrade my plan in the middle of my term?

You can upgrade or downgrade your plan at any time. However, if you're downgrading your PRO plan, you will remain on your existing plan until the end of your billing cycle. Any upgrades will happen immediately and the plan costs will be pro-rated accordingly.

What if I want to cancel my plan?

You can cancel at any time and your plan will expire at the end of your billing cycle. Until your plan expires, you will have full access to all your PRO features.

Do you offer refunds?

We offer a 14-day money-back guarantee. Reach out to us and tell us about your experience, and if, for whatever reason, you're still not satisfied, we'll provide you a refund.
