lazy loading adsense ad slots

[Fabio Fatuzzo]

Hello,

I love your pagespeed module.

Would it be possible to consider to add a lazy loading feature that applies to multiple AdSense ad slots which work for different ad sizes?

thanks,

fabio

Hi... How are you currently loading your ads? If it's via show_ads.js,
the make_show_ads_async filter sounds like what you want,
and it should pick up the slot size for the snippet.

Hi this is as a sample of adsense code I use and that already contains an async instruction within the script tag:

<style>

.example_responsive_1{width:300px;height:250px}

@media (min-width:500px) {.example_responsive_1 {width:336px;height:280px}}

@media (min-width:800px) {.example_responsive_1 {width:728px;height:90px}}

</style>

<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

<!-- 4icu.org-Level3_Bottom --> 

<ins class="adsbygoogle example_responsive_1" 

style="display:inline-block;min-width:250px;max-width:1140px;width:100%;height:100%" 

data-ad-client="ca-pub-MYADSENSEID" 

data-ad-slot="3298737036" 

data-ad-format="rectangle"></ins> 

<script>(adsbygoogle=window.adsbygoogle||[]).push({});</script>

However async still downloads the ads included in a page no matter whether they are located in the page if I am not wrong. So if I have three adsense ad slots in the same page async will defer the ad load but not avoid the heavy load itself like lazy loading would do.

If mod pagespeed would include a lazy load option that prevent the bottom ads to be downloaded before they are scrolled down and visible it would save so much total page size for those visitors that do not bother scrolling till the end of the page.

Our homepage at http://www.4icu.org takes 4 seconds to load and has a total size of 1.16MB when including two ad slots and a custom search engine (Ref. https://gtmetrix.com/reports/www.4icu.org/t92yPI4I )

Where a second test home page at http://www.4icu.org/index2.htm only takes 0.7 seconds and just 55kb when removing both adsense ad slots and the Google custom search engine (Ref. https://gtmetrix.com/reports/www.4icu.org/JTg1h6fK )

So more than 1 MB of total page size and 3 seconds of page load time are just due to the two Adsense slots and the Google Custom Search.

Any mod-pagespeed that would lazy load the adsense ad slots placed at the below the initial fold view would help limiting the page size and increase the page load speed considerably.

The only officially approved solution I found for lazy loading ads is the one suggested in the Double Click for Publishers help page at https://support.google.com/dfp_premium/answer/4578089#lazyloading by using specific tags.

If a specific option for lazy loading adsense ad slots was included in the mod-pagespeed it would be very beneficial for all publishers monetizing through Adsense.

Cheers
