i'm not sure if you are asking a generic question or a question about your niche.
there are plenty of areas where searches are low but competition is high...
typical examples of these would be technical terms in the scientific or medical fields specific to a particular (uncommon) disease or engineering problem where the costs of medication, consultancy or supplying the goods are extremely high and profitable.
As long as they have good relevance, there's no reason to avoid keywords that have high competition but low search. Just be realistic about how much performance to expect, and stay out of bidding wars.
Set your bids according to what will be cost-effective for your business, and let those keywords deliver whatever they deliver while you work on other things.
none, if there is competition - meaning there is search . What could be is- low competition- high search but not the other way around. Yes i agree that it may happen like if there will be a rumor going around that the next big thing is going to be "blue pillows "(just an example, talking about something new ) , then yes, there will be a lot of sites,posts, ads indexed for this keyword ,and in the end no one will be interested in " blue pillows " , so yes, there will be high competition, but no search.
I am agreed with (Yulia from DNP)because the reason is that we do not only follow the competition but also focus on the traffic towards that particular keyword and no one will waste his time and money on doing seo of such keywords that have not the meanings to cater the audience and hence i have come to the point that there many not such words that have high competition but less traffic.
