Scripts are separated into three categories:
- Critical
It must be loaded before the main page content.
- Non-critical
It can be loaded after main page content with delay as well.
- Special
Some special scripts (tracking, advertising, etc.) that can be loaded after main page content and after non-critical scripts with additional delay as well.
In most cases all scripts are non-critical and some are special as you can see by default settings. But sometimes particular scripts should be tuned individually.
General#
- Optimize loading non-critical and special
Enables loading optimization mode. Timeouts below are periods of user inactivity – no scroll, mouse move, etc. If the timeout is 0 then scripts will be only placed at the bottom of the page (just before the
body
closing tag). If the timeout is 1000 then it will be treated as infinity.- Defer non-critical
Enables loading optimization for non-critical scripts and delays it with the specified timeout.
- Defer special after non-critical
Enables loading optimization for special scripts and delays it with the specified timeout.
Note: if this is off, then all special scripts are considered non-critical.
- Deep hooks
Using deep scripts injection to make delay loading.
- Early preloading
Preloads scripts to be faster executed later.
- Fast loading
It improves scripts’ loading speed a little bit but might be incompatible with some scripts. So, it should be used carefully.
- First click delay
The timeout for loading the main scripts when clicking on an interactive element. Allows to correct situations when a click does not work the first time.
- Defer non-critical
- Group non-critical
Grouping improves pages’ loading speed but might be incompatible with some scripts. So, it should be used carefully.
Note: if ‘Defer special after non-critical’ is disabled, then all special scripts will also fall into this group.
Note. Special scripts are always loaded after non-critical. E.g. if deferring is disabled for special but non-critical are deferred, so special will be deferred too.
Minify#
- Enable
Optimizes JS code to have a smaller size but preserves any copyright information in comments.
- Remove copyright information
Removes all comments from JS code.
- Excludes
Scripts with URLs, IDs, or internal bodies matching the specified regular expressions will not be processed.
Non-critical#
- Inlined
Includes all inline scripts.
- Internal
Includes all internal (hosted on our site) scripts.
- External
Includes all external (hosted on the other sites) scripts.
- Exclude
Scripts with URLs, IDs, or internal bodies matching the specified regular expressions will be treated as critical.
- Include only
Only scripts with URLs, IDs, or internal bodies matching the specified regular expressions will be treated as non-critical.
Special#
Scripts with URLs, IDs, or internal bodies matching the specified regular expressions will be treated as special.
Not needed#
Scripts with URLs, IDs, or internal bodies matching the specified regular expressions will not be loaded.
Treat as scripts#
Some scripts might be loaded not via the script
tag, e.g. iframe
one. So, tags matching the specified XPath selectors will be treated as scripts and processed by other script settings excluding the source’s body.
Note. Specified iframe
tags are automatically excluded from Video and frames.
