I might be in holiday in the middle of a desert but it does not give you the right to ignore me.
I don't have 4G here. I have it in a nearby town, but not here. The 3G here is also non-existent and I am just about able to get 2G, but only just.
That's all OK because I can get WiFi. But the WiFi is shared with lots of other people and I imagine we aren't sharing a great signal because we're in the middle of a desert.
What's my point?
Test your websites for loading speed. Strangle your connection and then see what the other half experience.
I can't tell you how many links I've clicked on and abandoned because after 10 minutes I've exhausted my boredom threshold.
Think about your ad placements. You may have paid for me to see nothing depending on your contract. I may have clicked to open the page containing your ad but I haven't seen it.
There's no point in paying for Social advertising if my interest results in a spinning circle of frustration.
Don't send me emails telling me about your great new products if I can't view them on your website.
I could move 200yds to a point where the WiFi signal is stronger but I can't be bothered. Your content isn't that interesting, and if you want my engagement then you'll need to try harder.
