Now I've tested what Rasputin
say and blocked many thousands of ad networks in adsense. So instead of around 3000 I now have about 140. These are the ones that give me more than 50-100 views per month.
I thoroughly measured the speed before and after with gtmetrix, 5 to 10 tests. This from test server in London to my server in Oslo.
I see an improvement of about 1 second pageload. The number of requests has decreased from around 250 to 200.
My TTFB is usually around 240 ms, first rendering is around 500 ms, the DOM finished around 600 ms, and full pageload around 4.5 seconds including adsense.
Without adsense, full pageload is 2.4 seconds.
Finally, it will take about 2 seconds for scripts that are deferred, such as AddThis Social Buttons, Analytics, and Cookie Warning.
If one goes carefully into the waterfall on loading the page, I see that what's destroying is often .gif from ads.
And I use addthis buttons, but you must defer them because they are a big bottleneck.
Then I've contacted Google, but it normally take time before I get an answer.
And then I've thought about this, First, TTFB:
I have found this post which I think is still valid, although it is from 2013. TTFB is one of the most important factor for google SEO webpage speed and the first.
] And then about load speed and google seo speed factor.
I have read that if adsense ads delay page load, then probably this will not have anything to say for google seo speed factor. This is what I've asked Google about, but waiting for answers.
Here's another post about this, that's easy to understand:
So for now I say thank you for opinions about this and I'll be back when I hear more. SEO is not my favorite, but I see that I need to spend more time on this next to publishing good content.
