How Does Brand Authenticity Influence Buying Decisions?

Brand authenticity is the extent to which people perceive your business as genuine and consistent with its values and promises. Research suggests those perceptions can influence trust and willingness to buy. Your personality can help communicate who you are, but being unusual alone does not guarantee conversions.

So, that wonderfully specific part of you that keeps getting edited out of your content? It might deserve another look.

Who Is This For

You’re a coach, consultant, course creator, or entrepreneur who sounds interesting in conversation and strangely interchangeable online. Maybe you’ve been removing your humor, unusual examples, or strong opinions because you thought professional content required a personality reduction.

You want people to understand your expertise and feel comfortable choosing you. You also want to recognize yourself in what you publish.

Key Takeaways

• Brand authenticity involves credibility and follow-through, alongside personal expression.
• Research connects perceived authenticity with buying intentions in certain contexts.
• Purchase intentions are different from completed purchases.
• Your quirks work best when they help communicate something relevant.
• Test the effect on qualified inquiries and conversions instead of assuming personality automatically sells.

What Counts as Your “Weird” in Marketing

Your weird might be your theater background, your obsession with spreadsheets, or the way you explain business strategy through reality TV. It can also be a thoughtful opinion that differs from the advice everyone keeps repeating.

You don’t need an outrageous costume or an invented catchphrase. Your perspective already comes from a combination of experiences that other people don’t share.

The useful question is: which parts help someone understand your approach? A distinctive example earns its place when it makes the lesson clearer or gives a potential client insight into working with you.

What the Science Actually Says About Brand Authenticity

1. Authenticity can influence willingness to buy

A 2023 paper reported four experiments examining social media influencers’ authenticity. The researchers found that perceived authenticity increased purchase intentions, with trustworthiness and inspiration helping explain the relationship. They also found that inauthentic influencers could inspire purchases of pleasure-oriented products under certain conditions.

The practical lesson is that how people interpret you can affect their response to an offer. But this research measured purchase intentions around influencer endorsements, rather than completed sales of coaching services.

For your content, give readers accurate reasons to believe you. Show your thinking, use real examples, and make the experience you describe match what you deliver.

2. Credibility matters within authenticity

A 2022 study surveyed 380 brand users. It found positive relationships between authenticity dimensions, including credibility and integrity, and brand engagement, which was associated with usage intentions and willingness to pay a premium.

Because this was survey research, those relationships do not establish that adding personality causes sales. They do suggest that authenticity involves more than an entertaining presentation.

Your fun stories can introduce your approach. Your accurate advice and reliable delivery give people something substantial to evaluate.

3. Authenticity may be an expectation

Here’s the finding that keeps the conversation honest: a 2026 paper reported three experiments involving 1,617 participants. Authentic brands received more positive responses than inauthentic brands, but did not differ from a neutral baseline.

In those experiments, authenticity did not provide an automatic bonus. Appearing inauthentic carried the disadvantage.

You can take that as permission to stop performing a version of yourself you cannot sustain. It is also a reminder that “being yourself” still needs to sit alongside a useful offer.

How Your Weird Can Drive Conversions?

Your personality can give people information about your teaching style, values, and way of working. That is a practical application of the research, rather than proof that a quirky post will improve your conversion rate.

Imagine you’re a consultant who loves musical theater. You explain sales preparation through rehearsals: practice your opening, know the purpose of the conversation, and leave room to respond to the person in front of you.

The story shows how you teach and gives the reader useful advice. Someone who enjoys that approach can assess whether it suits them.

Now compare that with posting a theater joke that has no connection to your work. It may entertain people, but it provides less information about why they should hire you.

How to Bring Brand Authenticity Into Your Content?

Start with a problem your reader recognizes

Choose a question your audience actually asks. Then bring your personality into the explanation.

For example, a spreadsheet-loving coach could show how a simple tracking sheet reveals unfinished commitments. The spreadsheet becomes useful evidence of their approach, rather than a random personality announcement.

Share an opinion you can explain

You might believe daily posting is unrealistic for the clients you serve. Explain when a smaller publishing schedule makes sense, what it allows them to do, and what tradeoffs remain.

A supported opinion helps readers evaluate your judgment. Being provocative without an explanation gives them much less to work with.

Keep your promises visible

If you describe your process as simple, make the instructions easy to follow. If you promise personal feedback, explain what that includes and deliver it.

Brand authenticity becomes easier to assess when your words and your customer experience agree. A fabulous entrance still needs a good show behind it.

Give AI your real material

Start with a recording of yourself teaching, a relevant story, or an example you have permission to share. Ask AI to organize that material while preserving your language and flagging missing information.

Then check the result. Your weird is your superpower, and it deserves better than being replaced with “unlock your potential.”

Frequently Asked Questions

Recommendations

Choose one useful topic and create two versions: your usual presentation and one using a natural story or analogy. Keep the offer and call to action consistent so the comparison is more informative.

If possible, randomly split a comparable audience between versions. Comparing separate social posts is less conclusive because timing and distribution also change.

Track the action you care about and the relevant denominator. For example, divide qualified inquiries by landing-page visitors to calculate that conversion rate. A handful of responses is early feedback, so avoid declaring a winner too quickly.

Final Summary

Your personality gives potential clients a way to experience your perspective. Brand authenticity adds the credibility and consistency that help them evaluate whether your business delivers what it promises.

The research gives you reasons to take authenticity seriously, with clear limits around what it proves. Let your weird help explain your value, then measure what happens with your audience.
