FAQ: PDF tools keywords
- Which PDF tools keywords are worth building for?
- Look at the keyword-group table: groups marked "keep" passed our review, "red ocean = yes" means big brands already own the SERP, and the reason column says why. Higher volume × CPC means a bigger pond. Start with a "keep" group that is not a red ocean.
- Where does the data come from?
- Search volume, CPC and KD come from Similarweb keyword exports (global, last 28 days) — about 1.4 万 keywords that were each reviewed for "can an indie maker build a site for this". Payment evidence comes from TopCheckouts (checkout-page traffic, shown as tiers) and TrustMRR (founder-reported MRR, shown as site counts and a median band). The niche score is our own 0–100 blend of search value, paying sites, checkout traffic and 7-day new keywords.
- How often is it updated?
- Once a day, automatically, after our demand radar finishes its daily run. The date at the top of the board tells you which day you are looking at. A weekly report (in Chinese) comes out every Monday.
- How accurate is it?
- Volume and CPC are Similarweb estimates, so use them to compare niches and judge order of magnitude rather than as traffic forecasts. Payment evidence shows that someone is charging money in a niche; it is not revenue. Niches are rule-based, so a few keywords land in the wrong one.
- Why are payment signals shown as tiers instead of exact revenue?
- Exact MRR and checkout visits belong to TrustMRR and TopCheckouts. We publish the derived tier (none / weak / medium / strong, number of paying sites, median MRR band) and link each site back to its source page, where you can see the original figures.
- How do I use this to pick what to build?
- Start with the niche score, then look for medium or strong payment evidence, and skip niches marked "Free pond". Open a niche to see its top keyword groups with our verdict and reasoning, and pick a group marked "keep" that is not a red ocean for your first page.
- Do I need an account?
- Without an account you can read the niche board, the weekly report, the method page, the first 10 keyword groups of each niche, and the first 20 new words from the latest batch. A free account shows the first 30 groups, every new word in that batch, and one watch. Pro shows every group, filters, CSV export (20 a day), 90 days of new-word history, and unlimited watches.
- How much does it cost?
- Check out with PayPal. You can pay by card, no PayPal account needed. Pro is $12 a month, or $96 a year (that is $8 a month, paid once a year as $96, 33% less than paying monthly). You can cancel any time and keep Pro until the period you already paid for ends. A refund stops Pro immediately. PayPal issues the receipt. Email support@waxuqiu.com.
- How do I contact you?
- Email support@waxuqiu.com. If a payment did not finish, include the PayPal email on the order.
