I run my website through numerous of testing websites including Google page-speed insights. The problem is that Google AdSense code doesn't validate perfectly and for that reason, my score is no higher than 98%. This is what Google states:
- Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources:
http://pagead2.googlesyndication.com/…s/r20150409/r20150224/expansion_embed.jscould save 536B (2% reduction) after compression.
If I took off all advertisements, I would score 100%. The only way I could see me score 100% with AdSense is to make my webserver download their source code and modify it to comply with pagespeed insights but if I did that, then I'd get in trouble with AdSense as I'm then violating their policies.
Why should my site suffer the 2% if the problem is related to Google?
