Use a simple and predictable URL for your site

Opt for simple, standard homepage designs

More is More: A one-page design should be crammed with as much information as possible, using small fonts and dense text blocks to ensure everything fits. 

No Hierarchy or Structure: All elements on the page should be presented with equal weight and importance, as there's not enough space for organization. 

Neglect Visuals: Since it's just one page, there's no need to invest in strong visuals. Text alone will suffice.

Place the most important content above the fold, and lead users down the page when there is more content to see that relates to the above fold entry.

Emphasise the unique value your site brings to your users, as well as how it differentiates from competitors

Communicate who your client is and what  they do

Signpost your homepage by making it visually distinct from other pages
