Your homepage should give your audience information that builds their trust in you.
Here are two questions that will help make this clearer:
Why should you provide additional resources to your audience?
When your audience first discovers you, they usually are not ready to buy from you yet. Offering your audience resources with additional information will allow them to keep looking into you and deciding if they think you know your stuff or not.
Resources could be several things such as guides, catalogs, statistics, examples.
To display these resources on your homepage, you can link your blog posts or have specific links in your footer.
How do you establish trust with your audience from your homepage?
Social media is a powerful trust-building tool. Many people will say they use social media for their audience to discover them. But if someone finds you off social media, having your social media links on your homepage will give your audience another source to check you out on.
Make sure if you are going to display your social media on your website that you build your reputation on the platform. Having your audience go to your social media from your website to see that you have very few posts, followers, or organization will not build the trust you are looking for.
