SitePerfector vs Keysearch
Keysearch checks a difficulty score one keyword at a time. SitePerfector maps the whole market and shows you where your site sits on it.
SitePerfector is not a replacement for the Keysearch keyword or backlink database, and it does no marketplace research at all. It works from the other direction: it reads the live search results for your market, clusters them into a topic tree, lays your existing pages over that tree, and names the next page to write. If what you came for is a cheap keyword lookup, stay with Keysearch.

Themes, topics and pages for one market, with the call on each topic.
Who each one is for
Keysearch
SEO data suite
Bloggers, niche-site owners and small businesses who want keyword research without suite prices. Their homepage calls it the most affordable SEO tool for fast-growing sites and says they have been helping publishers, bloggers and small businesses since 2015. If you also sell on Etsy, Amazon or YouTube, the marketplace keyword tools are a reason to buy that nothing else in this category matches.
SitePerfector
Topic-first SEO
Site owners and small teams who have a site and a subject but no plan. The open question is which pages are worth building, in what order, and why. SitePerfector answers that, then gives you a blueprint for each page it puts on the list.
How the two approaches differ
Keyword tools hand you data and leave the decision to you. Topic-first SEO hands you a decision, with the reason and the competitors named. The method itself is explained in Topic-first SEO: what it is and why it works. This page only shows the contrast.
Keysearch
You start with
You start with a keyword search, a list of related terms, and a difficulty score on the rows that have one. The rest carry a Check button, and checking spends part of your allowance.
You publish
You publish whatever came out of the list, with the Content Assistant helping you optimise it once you have chosen.
What you get
- ✕You end up with a keyword list, and the scores are checked a keyword at a time out of an allowance.
- ✕Foresight suggests outward from the site you already have, so the market is never mapped in full.
- ✕There is no view of the pages you already own that serve no demand.
- ✕Nothing names the specific sites you would have to beat for a given topic.
SitePerfector
You start with
You start with your market, read from live search results and clustered into themes, topics and pages. Up to 1,500 keyword ideas are vetted per map and around a hundred earn a place, and you can see what was set aside and why.
You publish
You publish the page the map puts next, from a blueprint built out of the pages that rank today and the questions they leave unanswered. You write it yourself, edit an AI draft, or hand the brief to a writer.
What you get
- ✓You get a topic tree: themes, topics and pages, in the order worth building them.
- ✓Every topic carries a call, own it, build up to it or leave it, with the competing sites named.
- ✓Your own pages sit on the map, so you can see what is covered, what is missing and what already ranks.
- ✓Instead of a bought difficulty score, we read the live results page for each topic.
What each one does, job by job
Rows marked their strength are jobs Keysearch does better than SitePerfector.
| Job to be done | Keysearch | SitePerfector |
|---|---|---|
|
Cheapest paid keyword research with a difficulty score their strength |
Yes Reported at $24 a month, roughly the price they have held since 2015, and the cheapest real tool in this category. |
No We are not a lookup tool, and we do not sell a difficulty score at any price. |
|
Marketplace keyword research: Etsy, eBay, Amazon, Pinterest and YouTube their strength |
Yes All of it sits in the same subscription, and nothing else in this category serves a marketplace seller like that. |
No We read Google results only, so marketplace search is not covered. |
|
Backlink, PPC and keyword database their strength |
Partly Competitor keywords and backlink profiles come with the keyword database, with no paid-search research. |
No We have none of it, so keep Keysearch if a cheap lookup with backlinks is the job. |
|
Suggest keywords and content based on your own site their strength |
Yes Foresight takes your URL, analyses your niche, authority and rankings, then surfaces opportunities and reverse-engineers the top results. |
Yes We work the other way round, mapping and validating the whole market first, then laying your pages over it. |
|
Show you which pages you already have that serve no demand |
No Suggestions run outward from your site, so there is no market map for a page to be off. |
Yes The off-map list comes from a crawl of your site laid over the market, with no Search Console needed. |
|
Tell you the single next page to write, with the reasoning shown and what was ruled out |
Partly Foresight recommends keywords and shows what the top results are doing, without showing what it ruled out or who you would be beating. |
Yes You get a prioritized list of what to create, improve and leave, and you can open any topic to read the reasoning. |
|
Track brand mentions in ChatGPT, Gemini and Perplexity |
No There is no AI-visibility or prompt-tracking product, and their AI is generative: Content Assistant and Foresight. |
No We do not track AI mentions either, because AI answers cite what ranks and that is the work we support. |
|
Free public tools before you pay their strength |
Yes A free account with limited daily searches, plus a large shelf of free tools including the difficulty checker. |
Yes What Ranks Here, the Commodity Content Scanner and the AI-Tell Detector are free at /tools. |
Price |
Keysearch has no reachable public pricing page. Their homepage FAQ says plans start at $24 a month, and a third-party pricing tracker reports Starter at $24/mo and Pro at $48/mo, or roughly $20 and $40 a month on annual billing. Those tier figures are third-party, not from Keysearch. Their terms say a refund can be requested for up to 30 days from the initial purchase date. |
$7 for the first 14 days, then Basic $39/mo. Pro $99, Agency $179. Cancel anytime. |

Three differences you can check
1.Keysearch checks difficulty one keyword at a time. SitePerfector reads the results page for every topic in the map.
The Keysearch difficulty checker page describes the most results-aware formula in this category: they gather page one, then analyse backlinks, referring domains, the ranking strength of the main domain and how optimised the ranking pages are. On the same page they write that difficulty "can vary wildly depending on which SEO tools you are using", which is worth knowing before you plan on the number. On the long tail the score is not there by default either. You click Check, one keyword or a bulk batch at a time, out of a metered allowance. In our own measurement, 8 of 400 long-tail keywords came back with a difficulty value.
Run one search in your niche and look at the related-keyword list: some rows carry a difficulty score and the rest carry a Check button. Then type harbor freight air compressor, which has 49,500 searches a month and returns a difficulty of 0.

2.Foresight starts from your URL. SitePerfector starts from the market and then finds your site in it.
Foresight is the closest thing in this category to what SitePerfector does. You enter your website, it analyses your niche, authority and current rankings, surfaces opportunities scoped to your strengths, and reverse-engineers what the top results are doing. The difference is the order. Foresight suggests outward from the site you already have. SitePerfector reads roughly 40,000 ranked positions to build the market first, then lays your pages over it, and what comes back is three lists: covered, missing, and off the map. Only that order produces the off-map list, the pages you already own that serve no demand.
Run Foresight on your URL and look for a list of your existing pages that serve no demand. Then open the topic coverage map, where that list is the off-map bucket.

3.SitePerfector has no keyword or backlink database, and no marketplace research.
SitePerfector is not a replacement for the Keysearch keyword or backlink database, and it does no Etsy, Amazon or YouTube keyword research at all. If a cheap lookup with marketplace coverage is what you came for, stay where you are. If you sell on Etsy, I would keep Keysearch for the marketplace research whatever else you pay for. One thing to know on price: Keysearch has no public pricing page we could reach, so the tier figures here come from a third-party tracker, and only the "starting at just $24/month" line comes from Keysearch itself.
Open keysearch.co and look for a pricing page. The figures live in the homepage FAQ and behind signup, so start a free account and read the price in the app.

Questions
Is SitePerfector a Keysearch alternative?
For deciding what to publish, yes. For cheap keyword lookups, backlinks or marketplace research, no. Keysearch does those at a price nothing else matches, so running both is a normal setup.
How is SitePerfector different from Foresight?
Foresight starts from your website and suggests opportunities outward from it. We build the market map first, from live results, then lay your pages over it, and that order is what produces the off-map list of pages you already have that serve no demand. Both are real work, and they run in opposite directions.
Does SitePerfector track AI visibility?
No, and neither does Keysearch. Our position is that AI answers cite what ranks, so the work that gets you cited is the work that gets you ranked.
Can I use both?
Yes. Decide the page in SitePerfector, then run your keyword and marketplace lookups in Keysearch. Nothing on either side stops you.
