Semrush On Page SEO Checker alternative that writes the fix, with SEO Idea Units priced per plan

Semrush On Page SEO Checker runs on SEO Idea Units: 500 a month on Pro, 800 on Guru, 10 for the life of a free account. What it hands back is a list of ideas, and the rewriting is still yours. Below are the real limits from Semrush's knowledge base, five alternatives priced from their own pages, and a tool you can run right now on a page that should rank.

02 / The short answer

The right On Page SEO Checker alternative depends on what you want back from it

Semrush On Page SEO Checker is included in the SEO Toolkit from the Pro plan at $139.95 a month. Each keyword paired with a page costs one SEO Idea Unit, Pro gets 500 a month, and every time you re-collect ideas the units are spent again. The output is a prioritized to-do list, benchmarked against the top 10 results.

If you want the same kind of list inside a cheaper suite, Moz Pro starts at $99 a month and SE Ranking Core at $129. If you want the changes pushed to the site for you, Search Atlas OTTO starts at $99. If you want the corrected title, meta description, headings and opening paragraph written for each page, so the fix is ready to paste, SEOMake Starter is $49 a month with unlimited page audits.

03 / Checked at source

How Semrush On Page SEO Checker is metered, from Semrush's own documentation

Every alternatives list we found skips the unit, and the unit is where the cost lives. Semrush knowledge base article 1406, read on 19 September 2026, puts it in one line: one keyword entered is one SEO Idea Unit. Pair two keywords with the same landing page and you have spent two. The allowance is 500 a month on Pro, 800 on Guru and 2,000 on Business, and it resets on the first day of the month.

The catch is re-collection. The tool builds its ideas from the top 10 results at the moment it collects them, so to keep ideas current you schedule it to collect again, and each collection costs the units again. Semrush's own example is 100 keywords analyzed ten times in a month, which needs 1,000 units, or twice what Pro includes. On Pro, 100 tracked keywords can be refreshed five times a month, or 50 keywords about ten times.

What you get for each unit is a list of ideas in seven categories: content, semantics, strategy, backlinks, user experience, SERP features and technical SEO, each with a short explanation of why it matters. It is a good list. It is also a list. The new title tag, the meta description, the reworked headings and the extra section on the subtopic you missed still have to be written by someone, and for most teams that someone is the bottleneck.

Two more things have moved. The feature page, semrush.com/features/on-page-seo-checker/, now returns a 301 redirect to a general content marketing page, and the older knowledge base URLs for the tool return 404. The tool itself still loads inside Semrush. If you arrived here because the product page you remembered has gone, that is why. We cover the plan the tool comes with in full on our Semrush pricing page.

04 / Six options, priced

Semrush On Page SEO Checker alternatives compared on price, output and limits

Semrush and SE Ranking figures were read from each vendor's own pages on 19 September 2026. Moz Pro and Surfer prices come from our read on 10 September 2026, and Search Atlas from 5 September 2026. SE Ranking and Surfer geolocate their pricing, so both were re-read from a United States connection in September 2026 and show the dollar prices an American buyer sees.

Semrush On Page SEO Checker and five alternatives compared on price, what each returns, where it wins and where it falls short
Tool	Price to get it	What you get back	Where it wins	Where it falls short
Semrush On Page SEO Checker	Pro $139.95 a month; 500 SEO Idea Units	A prioritized list of ideas in seven categories, top 10 benchmarking, backlink prospects	Ideas come from the real top 10 for each keyword, and it imports pages from Search Console and Position Tracking	You get ideas, not rewritten copy, and every re-collection spends units again
Moz Pro On-Page Grader	Moz Pro Standard $99 a month, entry plan from $49	A grade and a checklist for one page against one keyword	Cheaper way into a full suite with Domain Authority and link data	A checklist, so the title, meta and headings are still yours to write
SE Ranking On-Page SEO Checker	Core $129 a month, $103.20 billed yearly	A page optimization score with AI recommendations	Rank tracking, audits and research in one suite for less than Semrush Pro	One manager seat on Core, and each extra seat costs from $16
Search Atlas OTTO	Starter $99 a month	40 on-page audits on 1 project, fixes deployed through a pixel	Pushes changes to the live site without a developer	Needs its script on your site, and 40 audits go fast
Surfer	Discovery $49 a month, billed yearly	Content Editor scoring against the pages that rank	Scores a draft against the live results while you edit	Built around drafts in its editor, not pages already live
SEOMake Starter	$49 a month, $490 a year	Score, issue list, rewritten title, meta, heading outline and intro, plus 20 drafts of 400 to 700 words a month	Writes the corrected copy for each page, with no unit meter on audits	No top 10 benchmarking, no backlink prospects, no Search Console import

We list where each competitor beats us, because several do. Semrush's top 10 benchmarking and backlink prospects are things we do not offer at all, and SE Ranking gives you rank tracking and a site audit for less than Semrush Pro.

05 / The numbers to budget

Four figures from Semrush's knowledge base that decide this

These come from articles 1406, 292 and 1547. The per-unit figures are simple division of the plan price by the allowance, and they ignore everything else the plan includes.

500

SEO Idea Units a month on Pro

Semrush knowledge base article 1406: one keyword paired with one page costs one unit. Pro gets 500, renewed on the first of the month. At $139.95 that is about 28 cents per keyword and page pair.

800

on Guru, at a higher unit price

Guru at $249.95 gives 800 units, about 31 cents each, so the upgrade buys other tools rather than cheaper ideas. Business gives 2,000 units for $499.95, about 25 cents each.

1,000

units for 100 keywords checked 10 times

That is Semrush's own example. Each re-collection of ideas spends the units again, so on Pro, 100 keywords can be refreshed five times a month before the allowance runs out.

units for life without the SEO Toolkit

A free account gets 10 units in total, and they never refresh. That is ten keyword and page pairs, which is enough to see what the report looks like and not enough to run it.

The per-unit price is not really the problem. At 28 cents an idea set, the tool is cheap. The problem is the hour of writing that follows each idea set, which the unit price does not show. If a content marketer at $45 an hour spends 20 minutes turning each page's ideas into a new title, meta and heading outline, 50 pages a month is about $750 of labor on top of the subscription. That is the number an alternative has to beat, and it is the reason we built the tool that writes the fix. The full cost of Semrush units per plan is worked through in Semrush SEO Ideas Units pricing.

06 / Which one to put on the card

When to keep On Page SEO Checker, and when to buy something else

Keep Semrush On Page SEO Checker if

You already pay for Semrush for keyword research and rank tracking.
You want ideas benchmarked against the actual top 10 in a specific city or country.
Backlink prospects and SERP feature ideas matter to you as much as copy.
You have writers with time, and what they lack is direction.

Buy an alternative if

The idea list keeps growing and the pages never get changed.
You are on a free account and have used your 10 lifetime units.
Re-collecting ideas eats your Pro allowance before the month is out.
On-page work is the only reason you would pay $139.95 a month.
You want the finished title, meta and headings, not a note saying they could be better.

Semrush's own setup wizard points at the pages worth fixing: Auto Import suggests pages ranking between position 11 and 100, the ones close enough to page one to move. That is the right list. What most teams do not have is the capacity to rewrite forty of them in a month. If that is your situation, the on-page SEO checker that writes the fix is the part worth paying for.

07 / Where we fit

What SEOMake does instead, and what it does not do

We are not a like-for-like copy of On Page SEO Checker, and saying so up front saves you a wasted trial. SEOMake does not pull the top 10 results for your keyword and benchmark against them, does not suggest backlink prospects and does not import pages from Search Console. If those are the parts you use, Semrush or SE Ranking is the closer match.

What SEOMake does is the step after the idea. Paste a live URL and the keyword it should rank for. It reads the page's on-page signals, gives it a score, lists the issues with the evidence it found for each, and writes the fix: a title under 60 characters with the keyword first, a meta description at the length Google shows, a heading outline built around the query, an opening paragraph, and the subtopics the page does not yet cover. On paid plans it also writes a 400 to 700 word draft that follows the outline.

There is no unit meter on audits. Starter is $49 a month, or $490 a year, with unlimited page audits and 20 drafts a month. Growth is $149 a month with 100 drafts. Every plan is on our pricing page, and the full output of an audit is shown on the SEO audit tool page.

08 / Before you cancel

Moving off On Page SEO Checker without losing work

Export the page and keyword pairs

The pairs you set up are the valuable part, because they record which page should rank for which query. Export or copy them out before you touch the project.

Mind the folder

Semrush removes the campaign only by deleting its folder, which also deletes Position Tracking, Site Audit and Backlink Audit in that folder, with no restore. Keep the project if you still use those.

Fix the top pages first

Start with the pairs Semrush marked as highest priority. Run each URL and keyword through SEOMake, paste in the corrected title, meta and headings, and move down the list.

09 / Asked and answered

Semrush On Page SEO Checker, question by question

What is the best Semrush On Page SEO Checker alternative?

It depends on what you want back. For another suite with an on-page grader, Moz Pro from $99 a month or SE Ranking Core at $129. For fixes pushed to the site, Search Atlas OTTO at $99. For the corrected title, meta, headings and intro written for each page, SEOMake Starter at $49 a month with unlimited audits.

How much does Semrush On Page SEO Checker cost?

It is not sold on its own. It is part of the Semrush SEO Toolkit: Pro at $139.95 a month gives 500 SEO Idea Units, Guru at $249.95 gives 800 and Business at $499.95 gives 2,000. Without the SEO Toolkit you get 10 units for the life of the account, per Semrush knowledge base article 1406.

What are SEO Idea Units in Semrush?

SEO Idea Units are the limit on Semrush On Page SEO Checker. Pairing one keyword with one landing page costs one unit, and two keywords on one page cost two. Limits renew on the first of each month. Re-collecting ideas for the same keywords spends units again, which is how 100 keywords can use 1,000 units.

Is Semrush On Page SEO Checker free?

Not in any useful sense. An account without the SEO Toolkit gets 10 SEO Idea Units, and Semrush says that allowance is for the lifetime of the account and does not refresh. Ten keyword and page pairs is a demo. Regular use starts with the Pro plan at $139.95 a month.

How do I use Semrush On Page SEO Checker?

Create a project, set the target location and device, then add landing pages with their keywords by Auto Import, manual entry, CSV, Search Console or Organic Rankings. Semrush then collects ideas against the top 10 for each keyword. Choose the location carefully: it cannot be changed after the campaign starts, so a new country means a new project.

Does Semrush On Page SEO Checker rewrite my content?

No. It returns ideas, such as adding semantically related words, reaching a target length or improving readability, with the reasoning behind each one. Someone still writes the new title, meta description and copy. That writing step is the gap most people are trying to close when they look for an alternative.

Is Semrush On Page SEO Checker accurate?

It is well grounded, because its ideas are built from the top 10 results for each keyword in the location you choose. The limits are in what it can see: user experience ideas need Google Analytics connected, and ideas reflect competitors at the moment of collection, so they go stale until you re-collect and spend units again.

What happens to my data if I stop using On Page SEO Checker?

Semrush deletes an On Page SEO Checker campaign only by deleting the folder it sits in, and that also removes the Position Tracking, Site Audit and Backlink Audit campaigns in the same folder. Semrush says the data cannot be restored. Export what you need before you cancel or restructure a project.

Semrush limits were read from semrush.com/kb/1406-seo-idea-units, kb/292, kb/563 and kb/564, and plan prices from kb/1547, on 19 September 2026. The feature page redirect was checked the same day. SE Ranking prices were read from its subscription page the same day. Moz Pro and Surfer figures come from our read on 10 September 2026 and Search Atlas from 5 September 2026. Vendor prices change. If yours differs, trust the checkout.
