How to optimize plugin settings
Ad Inserter is built for speed. In normal cases it should not significantly increase page loading time. Of course, if you are using many blocks this may slightly increase processing time, but still it should not cause any problem. In most cases the time needed to insert blocks is in the range of a few 10 milliseconds.
Usually the cause for long page loading time is slow loading and processing of external files needed by the ad codes you have inserted – check how ads are displayed. You can use debugging functions or individually disable (pause) insertion for each block to see which ads cause trouble. You can also check Network tab in Web inspector in the browser to see which files are slowing down the page.
Please note that Ad Inserter does not do any redirects, it only inserts ad codes as configured. If you see any report (for example from GTmetrix) suggesting to minimize redirects you need to first check where the redirects are located (on which page or domain) – if they are on other domains you don’t control, then there is nothing you can do (nobody except ad network can change this). URL redirection is a World Wide Web technique for transferring (redirrecting) a web page to a different URL address. Sometimes it’s necessary for your application to redirect the browser from one URL to another. There are several reasons ad networks or web applications issue redirects:
- To indicate the new location of a resource that has moved.
- To track clicks and impressions and log referring pages.
- To reserve multiple domains, allow for “user-friendly” or “vanity” domains and URLs, and catch misspelled/mistyped URLs.
- To connect between different parts of a site or application, different country-code top-level domains, different protocols (HTTP to HTTPS), different security policies (e.g. unauthenticated and authenticated pages) etc.
- To add a trailing slash to URL directory names to make their contents accessible to the browser.
Whatever the reason, redirects trigger an additional HTTP request-response cycle and add round-trip-time latency. Therefore, it’s important to minimize the number of redirects issued by your website. However, when the redirect is not on your domain (website) then you can’t change anything! You can only stop using ads (i.e. stop inserting code for ads) or services that cause unwanted redirects.
To figure out which code (block) you are inserting is responsible for the redirects you can selectively disable (pause) blocks to see the difference. Pause all the active blocks and then enable (unpause) one by one and check results after each change.
Please note that by simply disabling the plugin you are also disabling insertion of all the blocks (ad codes) you have configured and may use redirects, therefore, this does not mean that the plugin is doing redirects or slowing down your site. When you pause all the blocks the Ad Inserter is still active and processes the blocks, it only doesn’t insert any code on the pages. This is the real test to see the difference with and without Ad Inserter. With all blocks disabled you should see no difference in page loading time or performance scores when the plugin is active or disabled.
Processing of your PHP code used in some code blocks may also increase page loading time.
It is very easy to determine how much time Ad Inserter uses to insert the code. Log in as admin and go to a page where you would like to check Ad Inserter processing time. Enable debugging function Log Processing and check page source code at the bottom. Among other debugging data you should see the following lines:
PLUGIN CODE PROCESSING: 81.55 ms PLUGIN HOOKS PROCESSING: 0.00 ms BLOCK CODE PROCESSING: 210.08 ms TOTAL PROCESSING TIME: 291.63 ms
PLUGIN CODE PROCESSING time is the time used by the plugin to insert code blocks – this is the time that Ad Inserter itself actually adds to the page loading time (when the page is not cached).
PLUGIN HOOKS PROCESSING time is the time used to process your custom code using Ad Inserter custom hooks.
BLOCK CODE PROCESSING time is the time used to process your PHP code in Ad Inserter code blocks. If you are not using PHP code then this time should be 0.
TOTAL PROCESSING TIME is the total time used by the Ad Inserter plugin to process your PHP code and to insert the all the codes into the page.
Slower processing is mainly due to complex settings for paragraph insertion in combination with PHP functions for string processing. This might become noticeable if you are using Multibyte functions for paragraph counting.
However, slower page load may not be only because of plugin processing, the code you are inserting may also increase page load time. Check processing log of Ad Inserter as described above and use browser debugging functions to determine the nature of the problem – look also for render-blocking scripts.
Please note that when you disable Ad Inserter you also disable insertion of all codes and blocks you have configured. Therefore, if your issues go away when you disable the plugin THIS DOES NOT INDICATE any issue with the plugin! You need to try to disable individual codes to see which one is causing trouble.
Use back-end debugging to disable insertion of various codes to see which code is slowing your page.
PRO If you are using internal tracking, the website has a lot of visitors but not enough capacity on the server to process tracking requests, you may experience heavier load. In such case you need to disable internal tracking and use external tracking.
Check how much time Ad Inserter spent on processing the code. Enable debugging function Log Processing and check page source code at the bottom. Among other debugging data you should see plugin processing time (as described above).
Use browser debugging functions to determine the nature of the problem.
Check for render-blocking scripts – google for it, this is beyond the scope of plugin documentation.
Multibyte PHP functions for paragraph counting are much slower than standard ones. Use them only when insertion between paragraphs does not work properly on non-english pages.
If you are inserting the same ad with the same paragraph settings (except paragraph number) more than once you should combine them into one block. You can list all paragraph numbers for one code block. This will speed up processing as paragraphs will be counted only once.
Each plugin is slowing down the speed of your website. Try to reduce the number of installed plugins. If you are using a separate plugin for the following function you can remove the plugin and use Ad Inserter instead:
- To create or edit ads.txt file
- To insert header and footer code
- To insert AMP ads on AMP pages
- To insert PHP code
- For sticky (fixed) widgets – in some cases you may still need a dedicated plugin
- For widget logic to restrict widgets – for each block you can define conditions
- To detect ad blocking and display message
- To insert tracking codes including Google Analytics
- To insert ads at custom action hooks
Optimize page code and scripts on the page
However, some caching or optimizing plugins (like Autoptimize) may move it to the page footer or mark it with
