Rightmove do not offer a function to be able to boost an advert to the top of the listing pages. The listings are set by date added as a default but those searching online are also able to sort results by 'Lowest Price' and 'Highest Price' and Zoopla also offer 'Most Popular' (this will also allow you to see how many times your advert has been clicked on). If you are concerned about where your advert is appearing on the listing pages, please contact us for further advice.
