Summary: The Scanner Settings will allow you to modify and save your accessibility scanner’s Viewport Width, Evaluation Delay, and your Scan Rate Limit.
Access Scan Settings
To access these settings:
- Select the Websites menu from the main menu
- Choose a website from your list of websites and select the actions button for that website
- Under the Website Settings widget, locate and select Scanner Options
Viewport Width (in pixels)
The Viewport Width setting will allow you modify the viewport size of the Pope Tech Accessibility Scanner.
Websites will often change how they are presented to the user depending on the user’s device and viewport size. Because viewport sizes change going from device to device (desktop, tablet, mobile), the accessibility of the website may also change.
It can sometimes be beneficial to test a website for each of the website’s configured viewport sizes, especially when different content is shown at different sizes. For most responsive websites you can test a few of the pages on mobile or tablet sizes and all of the pages on desktop (or vice versa if most of your users are using mobile).
Pope Tech Tip
In your dashboard you can set up separate websites with the same domain. Utilizing this feature you are able to change the scanner’s viewport settings on each so that you can schedule regular scans of your website using different viewport widths.
Evaluation Delay (in milliseconds)
The default Evaluation Delay is 1000 milliseconds (1 second). This means the scanner waits 1 second after the page loads to evaluate the content. This can be increased or decreased depending on the website’s needs and capabilities. Evaluation Delay must be between 0 and 30,000 milliseconds (0 and 30 seconds).
Scan Rate Limit
The Scan Rate Limit will alter the speed (how many pages per minute) the website will be scanned at. The default Scan Rate Limit is 60 pages per minute. This can be sped up or slowed down depending on the needs and capabilities of the website being scanned.
For websites that are receiving any time-out errors during accessibility scans, it is recommended that you slow down the Scan Rate Limit settings until the time-out errors are no longer present. For more information review How to Resolve Scanner Timeouts article.
