I can’t say enough about being clear about the purpose of each page on your website. Maybe it’s one of my ’soapboxes’, but so many people either don’t know what they want people to do when they visit the website – or have unrealistic expectations.
Don’t expect anyone to buy from your home page – they can be engaged, but not sold to. They’ll need more in depth information before they take that step to part with money. Even Amazon don’t get many sales from the home page – and don’t expect to.
By all means put your phone number and email contact on every page, but think about what you really want people to do – that might be to find out more on another page, or buy online (when they’ve seen your products/services page, or call/email for more information, or make an appointment to meet with you or your representative.
Do make sure that everything on each page of your website helps to get your message across and contributes to the purpose of the page. That includes copy, graphics and images, information in columns on the right and left of the main text and every paragraph should lead the reader towards your purpose.
