The UX magazine has a good definition of 'trust':

• Your company is moral. Trust involves the belief that your company is law-abiding and fair while also showing that you cares about your customers.
• Your product will do what it claims to do. A consumer has expectations that your company’s product will live up to its claims, which are assumed to be accurate and unbiased.
• Information will be correct, complete, and unbiased. When people trust the information and choices presented, they are less likely to feel a need to go elsewhere.
• Your product or service has quality. People want to feel confident in their choices and we all want to feel confident that our digital devices are quality products that will safely hold important data.
• "A company will protect me." Security and privacy are increasingly a key concern for consumers as they navigate the digital world. People want to know that your company has their best interests in mind. Will your company safely store my personal credit card information and keep sensitive information private?

So what can you do to show your website visitors that your website is trustworthy?

Good looking websites with a professional design are much more trustworthy than websites that look as if they were created by amateurs. You should have beautiful web pages with functional design. A good website makes people want to learn more about your business and your projects.

If possible, show pictures of your team on your website. If you have customer testimonials or other third party rankings, show them on your web pages. People tend to trust a business more if other people tested it before.

Show real people who interact with your product and include a strong message and a clear call-to-action on your home page.

Beyond just having consistent uptime, fast load speeds, as well as a custom domain—there’s a few other things you can do to ensure the overall health of your website. Be sure that all of the information on your website in regards to shipping, contact information, product information and more is all up to date. Take some time to go through product descriptions, as well as old blog posts to ensure that there isn't any outdated information that may be misleading to a potential customer. A good way to subtly display that you're on-top of things is to have some sort of press page, or press mentions displayed directly on your storefront. For instance, here's what Freshly Picked includes on their storefront after being featured on Shark Tank and Ellen:

Of course, your website should have consistent uptime, fast-loading pages and a custom domain name. In addition, your web pages should not contain broken links, spelling mistakes, or other errors. You can check this with the website audit tool in SEOprofiler.

Keep your customers up-to-date by regularly publishing articles in your blog. If you do not have a blog, use social media to get in touch with your clients.

If it is difficult to find your contact information, people won't trust your business.

The easier it is to contact you, the better. List your full address, use contact forms, email, live-chat, phone, and social media.

"Google has released a broad core algorithm update. Some webmasters already noticed changes in their rankings. [...]

This week we released a broad core algorithm update, as we do several times per year. Our guidance about such updates remains the same as in March."

"This past March, Google was granted a patent that involves giving quality scores to queries. The patent refers to high scoring queries as augmentation queries. [...]

[The new version of the patent] tells us that it might use structured data in sites that appear for queries as synthetic queries, and if those meet the performance threshold, they may be added to the search results that appear for the original queries."

"Search ad spending growth decelerated across the engines in Q2 2018, digital agency Merkle reported in its Q2 2018 Digital Marketing Report. [...]

Google CPCs increasing faster than click volume. Overall, Google ad spend increased by 18 percent year over year, which represents the third straight quarter of slowing growth."

"It will not be possible to use adsenseformobileapps.com or other controls to keep mobile Display ads from showing on all apps, including interstitial ads. [...]

When Google Ads (formerly AdWords) uses the word 'simplify,' waves of concern ripple through the paid search community that the opposite will be true, controls will be lost and campaign performance will be affected negatively."
