I have been to an small business meetup in Manchester and been advised that I need to host my website in the UK and not in the US. The question is I expect most of my traffic to come from the UK so if hosting on US server would it be slow loading for UK audience?
This is a very debated question which in our opinion does matter where your server is hosted. It can effect performance and also technical support.
Solid performance is important not only for users but also the serps, Google does consider page speed in its search results. The key with performance is how optimised your website is, if you follow Google Page Speed insights and score 85+ we find hosting in other countries not an issue.
If you optimise your website I would not worry about which country it is hosted. There are opinions out there that suggest Google gives weight to UK websites which are hosted in the UK, but this has never been proven or mentioned by Google.
If you have limited technical knowledge and want to access techncial support Please Remember the time differences, some of our clients websites are hosted in US so its a nightmare when trying to communicate with them during UK working hours.
