I am currently giving keyword advise for an airline company. Since they have huge competition from sponsored 'Google Flights', I was really happy with the 'Keyword Opportunity'-metrics in the Keyword Explorer. However, Google flights does not seem to be consistently taken into account for the Keyword Opportunity score.
Eg. 'Place A to Place B' gets a low opportunity score (50-60), which makes sense, because there are four Adwords ads + a huge 'Google flights' box above the classic 10 blue links.
However 'Flight from Place A to Place B' gets a score of 90-100. If I check the last query, there is the same 4 Adwords ads, and also the Google Flights box.
The Opportunity score seems completely unreliable here?
