The individual is seeking to sell a portfolio of websites related to football and gambling due to the rapid success of a new startup. The main site, established in March 2014, has built a loyal user base, although its traffic might not seem substantial at first glance. It boasts an email database of over 50,000, offering considerable revenue potential through affiliate marketing and monthly subscriptions. Among its income sources, partnerships with sports betting companies have been lucrative, with substantial earnings from one prominent company mentioned as an example. Additionally, the site offers a premium subscription for exclusive data at £9.99 per month, already generating £450-£550 monthly, and there's potential for growth with further efforts. The operation of the site is largely automated, utilizing a unique algorithm and data feed for delivering tips and statistics, incurring a low annual data feed cost. The algorithm's uniqueness offers an opportunity to sell data access to other website owners, presenting an additional revenue stream. The seller emphasizes the site's significant potential for an ideal buyer and is willing to facilitate the transition by moving the site to the buyer's hosting account and providing post-purchase support. Included in the sale are the social media accounts and the valuable email database. The seller highlights the excellent potential returns given minimal time investment, estimating earnings of £3-5k per month with only 2-3 hours of weekly management. The opportunity is positioned as an attractive prospect, particularly for those knowledgeable about the niche's lucrative possibilities.
