How we measure

Every speed or security figure on this site comes from a free public tool that Julia Profit Studio does not own. This page says which tools, where each figure comes from, and what the figures do not mean.

The tools

• Google PageSpeed Insights, run on mobile and on desktop. It loads a page in a lab test and gives four scores from 0 to 100 (Performance, Accessibility, Best Practices and SEO), plus loading times. Open PageSpeed Insights (opens in a new tab)
• securityheaders.com, which reads the security headers a website sends with its pages and grades them from A+ to F. Open securityheaders.com (opens in a new tab)

Where each figure comes from

• Every PageSpeed figure shows the date and time it was measured, in New York time, and the mobile and desktop figures come from the same run. Google keeps a saved report for only about 30 to 45 days, so our buttons do not open an old report: they run the same test on the live site now, and you see the result of today.
• The security headers link opens securityheaders.com for the same address. That tool does not save reports: a fresh scan opens each time, so it shows the grade today. The grade shown on this site is from our scan on the date shown next to it.
• A figure without its report link and its date does not appear on this site. A check runs before every build of this site and stops it if a figure is missing either one.

Demo sites

The sites on our work page are demos for invented companies. On this site each one carries the label "Demo site for an invented company". They are not client sites. The businesses, and everything the demos say about them, are made up to show what a real site could look like.

What the figures do not mean

• Scores vary between runs. The network, the test server and the tool version all change the result, so a new test can give a slightly different figure.
• Results on your site depend on its content, its images, its hosting and the third-party scripts it loads, such as chat widgets, booking tools, analytics, ads and embedded maps or videos. A score on a demo site is not a promise of the same score on yours.
• PageSpeed Insights is a lab test on one page at one moment. An SEO score is not a search ranking.
• A security headers grade is not a claim that a site is secure. It checks only the headers a server sends. It does not test the site's code, its forms, its passwords, its hosting or the accounts behind it.

You can run the same tools on any site, including yours, on our check page.

How we test before launch

This is the process we follow for every site we launch.

• An automated pre-launch check. It reads every page of the built site and blocks the launch if it finds a placeholder still standing in for real content, a link to a Google tool without the setting that opens it in English, a time or date not written the US way, a long dash, or a claim the site owner has not yet confirmed in writing.
• Form tests on a local copy of the hosting platform. Before anything goes live, we run the forms against a local copy of the hosting platform, with no real email sent. Where a site has them, we test the spam check passing and failing, the hidden field that catches bots, posts sent too fast to come from a person, confirmation links, expired and altered links, downloads, one-click unsubscribe, and the cancelling of scheduled emails.
• A live look. We open the pages in a browser at phone and desktop widths and check them by eye.
• After launch. Once the new version is live, we measure every page with PageSpeed Insights, on mobile and desktop, and with securityheaders.com. We fix anything that costs a point, and measure again.

This is how we work. It is not a guarantee that a site is free of errors, or that a score will stay the same as the tools change.
