If you're searching for "SEOLumina alternative" or "SEOLumina vs JustNiches", you're probably weighing two TPT keyword research tools and want a clear-eyed look at where each one wins. This page is that look — written by working TPT sellers, not by an affiliate of either side.
Honest disclosure up top: as of April 2026, SEOLumina has limited public visibility in third-party SEO indexes (Ahrefs surfaces no organic traffic for the domain). That doesn't mean it's a bad tool — many useful SaaS products run quietly off paid acquisition or word-of-mouth — but it does mean the seller community hasn't yet built a strong shared opinion of what it does well or poorly. We'll compare based on what each tool publishes about itself.

Start Free →About SEOLumina
SEOLumina positions itself as an SEO-focused tool for content publishers, with TPT sellers as one segment of its audience. Its public website outlines features around keyword discovery and content suggestions. Beyond that, third-party visibility is currently limited — our research using Ahrefs (April 2026) shows the domain with minimal organic search footprint, suggesting the user base is either small, primarily acquired via paid channels, or both.
For a working seller, the practical implication is this: it's harder to find independent reviews, troubleshooting threads, or community recommendations for SEOLumina than for the more established TPT-adjacent tools. That's not disqualifying — every tool starts somewhere — but it does change the buyer's calculus.
About JustNiches
JustNiches is a TPT-specific keyword research tool built and maintained by a working Teachers Pay Teachers seller. The product's anchor feature is the Opportunity Score: a 0–100 number combining five factors (total products, low-review ratio, median reviews, popularity, and average rating) into a single decision-friendly answer. Pro tier additionally analyzes up to 5 pages (~120 products) per keyword and includes inline Google Trends data.
The tool ships in English and Thai out of the box. Free tier is genuinely free — 10 searches/day with no credit card. Pro annual is $70/year for Early Adopters (locked in forever; regular pricing moves to $99). About 5,684 unique keywords have been analyzed across the platform as of April 2026.
Feature differences that matter
1. The Opportunity Score
JustNiches' headline metric is the 0–100 Opportunity Score. Most TPT sellers use it as a "yes / no / maybe" signal: above 75 is usually worth a deeper look, below 40 is usually skip. The score is documented (we explain the five factors and weights publicly), so you can sanity-check whether the score aligns with your subject-area expertise. If SEOLumina has a comparable synthesized score, check their docs — we couldn't find one publicly described as of this writing.
2. Multi-page competition depth
Page 1 of a TPT search reveals the established giants. Pages 2–5 reveal the long tail of mid-rank competitors who are easier to displace. JustNiches Pro fetches up to 5 pages (~120 products) so the competition signal reflects the realistic landscape. Most other tools, including the standard view in many SEO platforms, focus on page 1 only.
3. Google Trends inline
JustNiches Pro shows the Google Trends curve next to each keyword's other metrics. That tells you whether interest is rising, seasonal, or fading — without switching to trends.google.com and re-typing the term. Useful for timing product launches.
4. Bilingual UI
JustNiches ships in English and Thai. SEOLumina's interface is English-only as far as we can tell. Niche but meaningful if you sell to or work with the Thai-speaking TPT seller community.
When to choose SEOLumina
SEOLumina might be the better fit if
- You're already using SEOLumina, your workflow is set up, and switching feels like more friction than gain.
- You need a feature that JustNiches doesn't currently offer and SEOLumina does — check their public site for current capabilities.
- You want a tool that's broader than TPT (covers other content publishing platforms too).
When to choose JustNiches
JustNiches is the better pick if
- You want a single 0–100 Opportunity Score per keyword instead of weighing multiple raw metrics yourself.
- You sell into competitive subjects and want to see pages 2–5 of TPT search competition, not just page 1.
- You want to test before you pay — JustNiches' free plan is genuinely free, no card.
- You want bilingual UI or you're price-sensitive ($70/year Early Adopter is the cheapest path to a full feature set).
- You value being able to see independent reviews and community discussion before committing — JustNiches has more visible footprint in TPT seller groups than SEOLumina does.
