Using social proof on your website is a no-brainer. It is kind of like being linked to the “cool kids” in high school or being known by a celebrity. The effect is real and something you should tap into because people are more likely to purchase when they see the “proof” that your product is good from others.
Social proof (also known as informational social influence) is a psychological and social phenomenon where people assume the actions of others in an attempt to reflect correct behavior in a given situation.
To be sure, there are many kinds of social proof. Depending on how you break it down, there can be as many as six or twelve.
Two types of social proofs that WordPress professionals can rely on are testimonials and social media. Today we are going to look at some tools that make it easier to implement these two types of social proof on your website.
Social media can become a great resource for proof of your product or service. There are two ways you can implement social media for proof.
First, you can use a social sharing plugin to show share counts for blog posts. Plugins such as Social Warfare shows sharing data.
Beware, however. You must guard against the negative effect of no shares at all. It looks much better when you have dozens, hundreds or, especially, thousands of shares.
For example, take a look at this image from a Buffer post. Wow, 1.7K shares! That looks impressive and makes it easier for others to share.

If you have no shares it could leave a negative impact. Notice what Collin Newcomer says at Revive,
First, set a minimum count to display share numbers. This means you can still have social share buttons on all of your pages, the buttons just won’t display share count numbers until a minimum number of shares is reached.This lets you still enable social interaction and take advantage of positive social proof while eliminating the possible pitfalls of negative social proof.
You can set your count to display when there is a certain number. This is a great idea.
Another way to use social media is to import social media testimonials you receive.
Testimonials you receive from customers is a tried and true method of social proof. These testimonials provide the credibility you need to show potential customers your worth. While there are several types of testimonials, I am referring to quote testimonials.
Using WordPress, you can easily embed tweets into your website. Once you have your praise tweets, you can do something similar to KWFinder,

It is easy to embed Tweets.
Choose embed from the drop-down arrow (see below)

Copy the highlighted code,

And, paste the code into your webpage.

And you get a nice looking embed of the tweet on the front end,

Twitter isn’t the only social media you can embed a post. You can do this with Facebook and Instagram as well.
For Facebook, you click three little dots and choose the embed,

Highlight and copy the embed code,

Then, paste it into your WordPress page just like you did for the tweet embed.
As with Twitter, you get a nice looking post from Facebook on the front end.
With these embeds, you can create columns and customize the look however you wish.
For Instagram, the process is the same as you see below.

Below are two WordPress plugins mentioned in a Facebook group that help you import social media testimonials.
I am an advocate of using a testimonial plugin that adds custom post types (CPT) to manage the testimonials. This allows you to manage the testimonials and includes them in a slider or as an archive on a page.
Social warfare – Here, Social Warfare, the social media plugin, has a custom section on the homepage using column classes in a text widget.

Custom Post Types can also serve you well to create both a testimonial and/or case study management.
There are many plugins in the repository that helps manage testimonials, and some include a slider layout. As with any plugin, check the reviews and the developer and test the functionality.
This example of a testimonial slider layout is from WPForms.

Looking for a plugin to add testimonials? There are several. Below are three resources that review several of those plugins.
