Things that can warp the div yield view are:
A drop in share price (IQE is a good example).
A special dividend, say from the sale of a large asset.
Personally, I used the above link to find companies to look into. Then once I found ones with good returns, I look at things like PE and NTA to see if it's a bargain, company news, ST threads, announcements, industry stats and signs of headwinds \ tailwinds, how much cash and debt they have, what might be effecting the current SP, general market sentiment to decide if it's a good time to buy (I go against the daily flow), etc. I also try to get an idea about how easy it would be to disrupt the business, also I use my subconscious to get a feel for whether it's a good buy.
