How to Use Google Trends for Coloring Book Niches [2026]

Google Trends tells you the direction of demand for a coloring book niche over time, not how many people search for it. The number it shows is relative, scaled 0 to 100, so a rising line means interest is climbing and a falling line means it is fading [1]. Read it before you commit a book to a niche, not after.

This guide gives you the exact settings to use, a season-vs-fad test that separates a niche returning every year from one that will not, and the fallback for when a niche is too small for Trends to read at all.

Google Trends is one signal, not the whole picture. The trending vs evergreen framework reads four together: the review-count ceiling of the top sellers, how recent their Best Sellers Rank (BSR) is, the rate of new releases, and the shape of the Google Trends line. This post is the deep dive on that last signal, because it is the one most publishers open, misread, and act on.

TL;DR:

• Google Trends shows relative demand direction (0 to 100), not search volume. Use it to spot rising, seasonal, and fading niches before you publish.
• Set the location to your main market, the range to 5 years, and a category filter so a word like "witch" reads as the hobby, not the news.
• A niche that spikes the same month every year is a season (evergreen). A niche that spikes once and never returns is a fad. The 5-year shape tells them apart.
• If a niche term is too small to register, Trends only shows noise. Fall back to Amazon signals: BSR, review counts, and new-release rate.

What does Google Trends actually tell you about a coloring book niche?

It tells you whether interest in a niche is rising, steady, seasonal, or falling, on a relative scale. Google Trends divides each data point "by the total searches of the geography and time range it represents to compare relative popularity," then scales the result "on a range of 0 to 100" [1]. So 100 is the niche's own peak, not a sales figure.

This is the part most publishers get wrong. A niche sitting at 60 is not "bigger" than a niche sitting at 40, because each chart is scaled to its own history. The two numbers describe two different search terms and cannot be compared side by side unless you put them on the same chart. What you read is the shape of the line, never the height of a single point.

Why bother, then? Because search interest is a leading indicator. People search a niche before they buy in it, so a Trends line that turns up or down often moves 6 to 12 months before the change shows up in Amazon sales rank. That head start is the whole value: it lets you enter a niche while the window is still opening instead of after every other publisher has spotted it.

How do you set up Google Trends for coloring book niches?

Enter the niche the way a buyer would search it, set the location to your main marketplace, set the range to the past 5 years, and apply a category filter so an ambiguous word resolves to the hobby. Those four settings turn a noisy chart into a readable demand curve. The defaults will mislead you.

Walk through each one:

• Search term: use the phrase a buyer types, and test both the broad and the specific version ("cottagecore" and "cottagecore coloring book"). The bare subject term carries more volume and a cleaner signal; the full phrase confirms buying intent when it has enough data.
• Location: set it to your largest market. The US is the biggest for most publishers on Amazon Kindle Direct Publishing (KDP), and demand curves differ by country, so a global default blurs the picture you actually sell into.
• Time range: choose the past 5 years. The 12-month default hides both the multi-year trend cycle and the annual seasonality, which are the two things you most need to see.
• Category: "If you're using Trends to search for a word that has multiple meanings, you can filter your results to a certain category to get data for the right version of the word" [2]. A filter keeps "dragon," "witch," or "botanical" on the craft-and-hobby meaning rather than mixing in film, news, or gardening searches.

Leave the search type on Web Search. Image or YouTube search can be useful later, but web search is the demand signal that maps to a book buyer looking for a coloring title.

How do you tell a seasonal niche from a fading fad?

Look at whether the spike repeats. A seasonal niche spikes the same month every year, then resets: Halloween climbs every October, Christmas every December. A fad spikes once, often from a viral moment, then slides back toward zero and never returns. The repeat is the entire test, and only the 5-year view shows it.

A seasonal niche draws a saw-tooth: one peak per year at the same time, holding roughly the same height across years. That is an evergreen pattern in disguise, and it is publishable. The move is to list the book 2 to 3 months ahead of its season so Amazon indexes it and it collects reviews before the buying window opens, not during it.

A fad draws a single hump. For its first few months it looks identical to a genuinely rising niche, which is exactly the trap. The 5-year range separates them: a fad already has its peak behind it with nothing replacing the attention, while a real rising niche climbs from the bottom left with no earlier collapse in view.

Watch for the third shape too: a niche past one big peak that has settled into a lower, steady band. That is a former trend that found a floor, and it is still viable, just smaller than its peak made it look. The durable niches that sell year after year are the flat, high plateaus that never spiked at all.

Which coloring book search terms should you compare?

Compare your candidate against a niche you already know is evergreen, like mandala, so the 0 to 100 scale gets a reference point. Then read the Related queries panel: "Rising" and "Breakout" terms surface sub-niches gaining interest faster than the broad term, which is where the open pockets tend to be.

The compare feature is the fix for the relative-scale problem from the first section. Add a second term to the chart, and Google Trends normalizes both against the same scale. Now you can see whether your niche runs at a fraction of mandala's steady demand or rivals it. A lone chart at 70 means nothing; the same chart next to a known baseline means a lot.

The Related queries box is your sub-niche radar. "Top searches are terms that are most frequently searched with the term you entered," and "Rising searches" are the ones that "had the most significant growth in volume in the requested time period" [3]. When you see "Breakout" instead of a percentage, the term "grew by more than 5000%" [3]. "Cat coloring book" is saturated, but a rising related query can point you to the specific angle that is not.

One caution: rising is not the same as durable. A breakout query is often a fad in its first act, so run the season-vs-fad test on any rising term before you build a book around it.

What if your niche is too small to show up on Google Trends?

Then Trends can only show you noise, and you ignore it. Google warns that statistical noise "is most noticeable on queries with low or no search interest" and that "apparent one-off spikes should not be interpreted as real search activity" [1]. Most specific coloring sub-niches sit below that threshold, so validate them on Amazon instead.

Here is the mechanism. Trends samples and normalizes its data, and a narrow term like "maine coon coloring book" produces a jumpy line that is sampling artifact, not demand. Reading a story into that jitter is the single most common Google Trends mistake in niche research. If the line looks like static, it is static.

The fallback is Amazon's own signals, which live at exactly the sub-niche level where Trends goes blind:

• Best Sellers Rank: check the top sellers' rank to confirm real, recent sales. The BSR primer covers how to read the number and turn it into a rough monthly sales estimate.
• Review ceiling: count the reviews on the top 10 books. A low ceiling means no entrenched winner yet.
• New-release rate: sort by newest and count titles from the last 30 days to gauge how fast supply is arriving.

The niche finder returns scored sub-niches with those Amazon signals already attached, which is the layer Trends cannot reach. The rule of thumb: use Trends for the broad niche (is the category rising or fading?) and Amazon for the specific sub-niche (is this exact angle open?).

How does Google Trends fit into the rest of your niche research?

Use it as your early-warning signal and nothing more. Search interest moves before sales, so Trends can flag a niche turning up or down months ahead of Amazon. But it cannot tell you whether a niche sells or whether it is already saturated, so pair the direction it gives you with the signals that measure real demand and competition.

The clean workflow runs in that order. Start on Google Trends to pick the broad direction and rule out the obvious fads. Move to the four-signal read and the niche finder to confirm the specific book has buyers and room. Only then do you produce, because a validated niche with a weak execution still fails.

Once a niche checks out on both the search-interest side and the Amazon side, the bottleneck stops being research and becomes production. That is where BookIllustrationAI turns a validated niche into print-ready interior pages, so you can act on an open window while it is still open. You can see what the output looks like before you start, then run your next candidate niche through the same two-step check.
