Launched to the world in September 2017, TikTok is the first Chinese app to pose a serious threat to Western social media companies as it attracts hundreds of millions of Generation Z users around the globe

Privately-owned parent company Bytedance earned $7 billion in online advertising revenues in 2018 and is valued at $75 billion, placing it ahead of Uber as the world’s most valuable internet start-up, with an IPO likely this year

Google Jobs launched in the UK in July 2018 and enjoys partnerships with all the major portals other than Indeed

The sharp decline in sales and shift to lettings, sluggish price growth and pressure on estate agents’ commissions, are making marketing key to driving transactional activity in a longer sales funnel.
