The inbuilt pressure when letting and estate agents market themselves, is that those letting and estate agents always want to talk about themselves and what their services can do. Landlords and potential Vendors, meanwhile, only want to know only what those agency services can do for them. Instead of taking about yourself, your agency, what you have sold, how big your agency is, how you have smashed your target, how bloody wonderful you are, why not talk about stuff that excites, interests, entertains or educates those potential landlords/house sellers, by writing stuff that will interest the said landlord or potential property seller. By creating content as a foundation of your marketing allows you to truly place yourself in your potential landlords or potential house sellers' shoes, to adopt their view points, and to consider their thoughts, beliefs, worries, wants and needs.
Have a great Bank Holiday!
