We have recently increased the number of ad links from 7 to 10.
This was done in response to the increasing number of people with larger screens.
In order to raise it further, we would have to discuss the issue with our advertising partner.
However, our research has shown that 10 links is optimum, as few people scroll down the parking page in order to view additional links.
Also, relatively few keywords generate more than 10 ad links.
Again, thanks for the suggestion, but we have no immediate plans to change the parking pages.
That's a good idea, but we have to run everything to do with changing the page by our advertising partner first.
A search box might adversely affect the parker's CTR, as the visitor may be more likely to search directly for what they want, rather than to browse the links listed and our advertising partner may not want to use a pop-up window.
I'll note your suggestion though, and it will be passed onto the parking team.
Thanks for the feedback everyone - it's great to get new ideas and suggestions from the people most in the know - our customers!
