Pop-ups are really taking over the internet. Again. I'm all for optimizing/growth-hacking/whathaveyous, but when it detracts from the reading experience then maybe you've gone too far?
This page had social share buttons on the side, intercom(?) looking button, and a popup to give them my email all orchestrated to fade-in/pop-in before I had a chance to really dig into the article. And now I wont.
I never ever see popups. I do 90% of my browsing in emacs, using emacs-w3m in text mode, so don't see images (except when I manually choose to view them) and emacs-w3m does not support javascript. It works very well for the majority of websites out there.
For those sites that are broken without javascript, and which I absolutely must use, I use Firefox with the NoScript and Request Policy extensions (though I'm migrating to Pale Moon because Pentadactyl is going to break on newer versions of Firefox) and Privoxy for ad blocking. For the few sites that don't work with Firefox, I use Opera, again with Privoxy for ad blocking.
As a result, 99% of the time, the only ads I ever see are text-based, and only when embedded directly in the page I'm reading.
Definitely agree with the power of referrals. Our customers have significantly higher conversion and (it looks like) a longer lifetime if they were referred by an existing customer.
In case you were confused by the introduction of the acronym NPS, (as I was) it means "Net Promoter Score". It's a customer loyalty metric: https://en.wikipedia.org/wiki/Net_Promoter
Quick, before reading the article, what do you think they found?
