Interesting tips. A lot of people have different versions of what they think works best for LinkedIn.
My tip regarding the list of keywords: don't delete it. LinkedIn is essentially a search engine. If you remove keywords, you will cut yourself out of search results. So as a compromise, I'd say keep the list, but don't put it at the top.
You don't delete it you move it to the appropriate place.
You place it under skills.
You place it under the appropriate job experience.
But if you're trying to game the search by having everything keyword under the sun this will not work as you hope.
Like I said, a lot of people have different versions of what they think works best for LinkedIn. Ultimately, it's a search engine so different strategies will work for different people. (But really if no one is reading your profile summary, no one is reading your job experience either.)
It's also entirely possible to write 2 descriptive lines that show up in a profile summary...and also more. I think you get like 350 words in this area. If you only write 2 lines, you really cut out the opportunity to describe yourself in more detail.
Anyway, interesting tips. I hope they work for someone.
I just want to state that its less of "thinking what works best" and what I'm doing is creating hypotheses, experimenting and capturing the results. So I like to think I'm closer to the truth than just writing nonsense:
I plan on showing more of this information if people keep showing interest.
Great, I'm glad you can back up your post with your own data. There are different approaches to LinkedIn and it's good that people can try out what works for them.
Another suggestion for your post: in your first comment to me you said your advice was to move that keyword list to different areas of your profile. In your post, you don't make that suggestion or any suggestion at all. If your advice is to move the list to different areas, you might want to update your post to include that extra detail. Right now it reads as though your advice is simply to delete those keywords.
