Why is the screenshot not being taken for a specific page in Behavior Map?

Here are possible reasons a page is not displayed in Behavior Map in the Analytics module:

• You have misspelled the page URL. Always double-check your page URL by comparing it to the live version.
• The page's URL is broken.
• No interaction (visits, clicks etc.) have been logged on the specific page since it was added to the Behavior Map. When a visit/interaction takes place, a screenshot will be generated to collect data on that specific page.
• The URL you have entered is behind a login (intranet, etc.). Siteimprove's screenshot crawlers cannot crawl pages behind a login.
• A cookie banner on the page may be blocking interactions. This is highly based on the setup of your cookie banner. 
• Your user does not allow/declines cookies, therefore no interactions will be logged and no screenshot will be taken. This only happens if all of your users decline cookies.
• Your JavaScript loads very slowly on a page. Slow JavaScript could cause our screenshot crawler to not being able to render a screenshot of your page due to slow loading time.
