Thanks to Theo Smith's post I've seen a massive increase in views, clicks, likes and comments on posts I've shared on LinkedIn. How? I've stopped using the image preview feature (by which I mean the rich link, where a picture pops up as below). 

Here is how I used to typically post links to LinkedIn, as you can see, this recent one didn't go too well:

Pretty disappointing results for a post that's been popular elsewhere. I decided to re-share this post half-an-hour ago. In that space of time, it has already overtaken in number of views, and got 1 like and 3 clicks, so it seems it's received twice as much visibility on the network already:

What's interesting is that LinkedIn automatically generates an image preview, so if you're posting directly (or using Buffer), you'll need to physically remove the preview to try this trick:

Generally speaking, when you post on LinkedIn, you get a much longer tail of visibility and interaction than on other networks, so here's another example of a post shared a week ago, without an image preview:

The difference is pretty striking. While this technique might not last forever, it's worth giving it a try right now to make sure the right people get an opportunity to read your content.
