Facts read from this source
-
No flickering claim Report an error
“In Webtrends Optimize, we do not experience content flickering for any test type, as long as the recommended approach is followed as described in this document.”
-
Tag implementation requirements Report an error
“Put the tag in the <head> Write it out as specified, with the HTML, not through JavaScript. Do not add async or defer attributes”
-
Flicker risk conditions Report an error
“if our tag was in the <body> or included async or defer attributes, or if it was loaded into an async tag manager like Google Tag Manager, you’ll find that our tag is written to the page after some visual elements may have already loaded – thus too late to avoid content flickering.”
-
Trigger modes Report an error
““head” – immediately “dom” – on DOMContentLoaded “load” – on window.onload”
-
Async test fetching Report an error
“From that moment, we then fetch tests asynchronously – evaluation is done in our servers and we only return the tests a user should fall into.”
-
Mask1 configuration Report an error
“we have a setting in your tag that allows you to either mask the page all of the time while this evaluation happens or manually controlled using an array of regexs (referred to commonly as “the whitelist”).”
-
Mask2 waiting Report an error
“Apply a 2nd layer of masking. Mask 2. Poll/wait for your conditions to be fulfilled. Run your transformations Remove Mask 2.”
-
Mask2 effort Report an error
“At most, 1 line of CSS to manage per test, assuming you’re a developer scripting your tests.”
-
Obf framework Report an error
“If you’re running scripted tests, we suggest using the Optimize Build Framework (OBF) in which case there’s a single CSS rule near the top of the file to manage Mask 2.”
-
Ticket channel Report an error
