An influencer’s follower count can be a hot topic for authors, publishers, and digital marketers. In this article, we’ll shed light on follower counts and debunk the myth that small accounts aren’t worth the investment in book marketing campaigns.

Influencer Tier	Follower Count	Engagement Rate	Best Use Case for Book Campaigns
Nano	< 1,000	Highest (~5%–8%)	Hyper-niche reviews, authentic word-of-mouth, tight-knit communities
Micro	1,000 – 5,000	Very High (~4%–6%)	High trust, active commenter engagement, cost-effective volume
Midi	5,000 – 50,000	Moderate (~2%–4%)	Broader reach, consistent aesthetic quality, strong genre authority
Macro	50,000 – 100,000	Lower (~1%–2%)	Large-scale visibility, brand prestige, launching major releases
Mega	> 100,000	Lowest (~1%)	Mass-market awareness, viral awareness pushes, broad audience reach

The Myth of the Macro-Influencer in Book Marketing

As an author or publisher, it’s understandable that you want as many people as possible to see your book. This might lead you to think that big name influencers or content creators with a strong social presence are the answer. Whilst it’s great if you can secure collaborations with major influencers for your title, you could be missing out on greater wins if you put all of your budget behind this one marketing strategy.

At Bookinfluencers.com, we celebrate all bookish content creators – big and small. When booking in a campaign, you can specify At Bookinfluencers.com, we celebrate all bookish content creators—big and small. When booking a campaign with us, you can specify your desired influencer follower count tier to match your budget and goals:

• Nano: <1,000 followers
• Micro: 1,000 – 5,000 followers
• Midi: 5,000 – 50,000 followers
• Macro: 50,000 – 100,000 followers
• Mega: >100,000 followers

It’s important to offer this flexibility, but we also want to challenge the assumption that working with smaller accounts on bookish promotions doesn’t pay off.

What the Data Tells Us About Engagement Rates

Our sister agency, Tandem Collective, focuses heavily on collective follower count. Their data repeatedly demonstrates a key trend in influencer marketing: the higher an individual’s follower count, the lower their average engagement rate on a campaign.

Over four years of data tracking, results consistently highlight the power of peer-to-peer micro-marketing versus relying solely on single macro-influencer campaigns.

Why Smaller Accounts Often Deliver Higher ROI

Content Volume: Dividing a campaign budget across 20 to 50 micro-creators generates significantly more total review posts, Stories, and videos than hiring a single mega-influencer.

Organic Audience Growth: Creators with smaller followings prioritize organic community building over rapid follower acquisition.

Higher Audience Trust: Followers engage actively through comments and likes, viewing recommendations as trusted advice from a peer rather than a paid sponsorship.

Maximizing Reach with TikTok Spark Ads

Sometimes, we just want our book to be seen by as many people as possible. With TikTok’s Spark Ads feature, this doesn’t have to cost a lot of money. With permission from the creator, TikTok Ads enable us to put media budget behind any piece of content, in order to generate views, engagements or click-throughs to other websites, such as book retailers. A media-budget of £100 can achieve thousands of views, for example. We can target a certain audience by location, age-group, interest and behaviour, to make sure the content is reaching the relevant people. The advantage of this method is that creator size no longer matters, as any video can be boosted in order to achieve the desired number of views and engagements. If you’re interested in learning more about this feature, get in touch, or you can find an overview of our SparkAds campaign bolt-ons here.

ChallyPop: Prioritizing Content Quality Over Quantity

Another platform in the Bookinfluencers family is ChallyPop – a competition platform where everyone has the potential to be a paid Instagram, TikTok or YouTube creator, regardless of follower count. ChallyPop prioritises quality and creativity of content over quantity of followers, offering a range of packages for author and publishing clients. Creators enter competitions by uploading content in response to a given challenge. A panel of judges then votes on the top 10-20 pieces of content, with each winner receiving a cash prize.

“Working with macro-creators has become unrealistic for many marketers. ChallyPop is our answer to creator fatigue, consumer cynicism, shrinking budgets, and lower return-on-investment.”

Finding the Right Balance for Your Campaign

The most effective book marketing strategies rarely rely on a single creator size. While macro-creators offer immediate prestige and mass-market reach, smaller bookish creators deliver higher engagement, authentic trust, and greater overall volume.

For optimal campaign performance, combine peer-to-peer micro-influencer activity with targeted paid boosts (such as TikTok Spark Ads) to achieve both deep community engagement and wide audience reach.

In short, give small bookish creators a chance, as they could help you to achieve a bigger impact than you expected!
