Blogging Tools

We Priced a Year of 16 AI SEO and Blogging Tools. For 13, the Monthly Price Times 12 Is Wrong.

The numbers, up front

• 11 of 16 tools advertise a lowest monthly figure that is an annual rate, only available if you pay for a year.
• 13 of 16 cost more over a no-commitment year than the advertised monthly price times twelve. The other three (ChatGPT Plus, Clearscope and Ubersuggest) advertise their monthly rate and have no gap.
• Across all 16, the advertised prices add up to $10,034.16 a year. A year of the same use with no lock-in costs $13,487.40, 34.4 percent more.
• Ahrefs advertises $29 a month. Its $29 Starter plan tracks 50 keywords, so tracking 100 means Lite at $129, and a year of that costs $1,548 paid monthly or $1,290 paid yearly. Against $348, that is the widest gap in the set, and it exists only because the workload crosses Starter’s limit.
• Grammarly advertises $12. Paid monthly it is $30, so a flexible year costs $360, 2.5 times the sticker.
• Of 7 SEO suites, 2 charge extra to track prompts in AI search, 3 include it, 1 does not offer it and 1 sells it in units that do not compare.
• For 8 of 16, the vendor publishes no price for using more than the entry plan allows. The plan stops you, pushes you up a tier, or sells top-ups at an unpublished price. A ninth, Jasper, states no usage cap at all.

Why multiplying by twelve gets it wrong

“Best AI tools” roundups usually quote a single monthly figure for each tool. A reader budgeting for the year does the obvious sum and multiplies it by twelve. That sum fails for three separate reasons, and most of the tools in this study trip at least one of them.

1. The advertised figure is an annual rate. Surfer’s $49, Grammarly’s $12 and Semrush’s $117.33 are what each month costs when you pay for the whole year up front. Pay month to month and the rate is higher.
2. The cheapest plan cannot do the job. Ahrefs Starter tracks 50 keywords and Keysearch Starter tracks 80. A blog tracking 100 has to buy the next tier.
3. The feature that makes it an “AI SEO tool” is sold separately. Tracking whether your brand shows up in ChatGPT or Google’s AI answers is included on some suites and a paid extra on others.

We define the times-twelve gap as the difference between a tool’s advertised monthly price multiplied by twelve and the cheapest year that covers real use without a long commitment. It is the number a reader discovers on the first invoice after the free trial.

The workload we priced

A gap only means something against a fixed amount of work, so we priced every tool against the same small operation: one person running one blog and publishing two posts a week. We kept it modest on purpose. If the gap shows up at this size, it will not shrink for a busier site.

• For the SEO suites, one site and 100 tracked keywords. A second pass adds tracking 50 prompts in AI search, refreshed at least weekly, in ChatGPT and at least one of Google’s AI surfaces.
• For the content optimisers, eight posts optimised a month on one seat.
• For the AI writers, eight long-form drafts a month on one seat.
• For Grammarly, editing the same eight posts.
• For Originality.ai, an AI and plagiarism scan of eight 1,500-word posts, which uses 240 credits a month.

For each tool we then recorded two annual figures. The locked-in year is the cheapest way to buy twelve months, annual prepayment included. The no-lock-in year is twelve months paid month to month, which is what anyone who wants to keep the option of cancelling will pay. The gap in the chart and the table is measured on the no-lock-in year.

All 16 tools, priced for a year

Sorted by the size of the gap. “Advertised” is the lowest per-month figure the vendor’s pricing page shows for its entry paid plan. Where the workload needs a bigger plan, the plan named under the tool is the one we priced.

Eleven figures in that table are worked out and not read, and the dataset marks each one. Eight of the locked-in years are an annual per-month rate times twelve, because Semrush, SE Ranking, Moz Pro, Surfer, Frase, Jasper, Writesonic and Grammarly print no yearly total. Ahrefs’ $1,290 applies its help centre’s rule that a yearly plan costs ten months’ price to Lite, whose annual price is not printed. Surfer shows no month-to-month price for its content plans, only “Billed yearly” beside a saving of $120, so its $59 monthly rate is worked back from that saving. Writesonic’s monthly price sits behind a toggle we could not read, so its $99 comes from “Save $240/year” the same way.

Locking in closes most of the gap, and costs you the exit

Pay for a year up front and the arithmetic mostly works: 13 of the 16 locked-in years equal the sticker times twelve. That is partly by construction, since several of those totals are the annual rate times twelve. The exceptions are the two tools whose entry plan cannot handle 100 keywords. Ahrefs costs $1,290 a year on Lite even with its annual discount, which its help centre describes as ten months’ price for twelve, and Keysearch costs $480 a year on Pro. Claude Pro is the only one that comes in under: $17 a month times twelve is $204, and the annual plan is billed at $200.

The price of the saving is flexibility. Surfer’s pricing page says you are charged “for the entire year” when you buy. Semrush’s seven-day refund covers only initial subscriptions of twelve months or longer and initial add-on purchases. SE Ranking says payments are non-refundable unless the service was not delivered. Mangools refunds within 48 hours of payment, though not on two consecutive subscriptions. A blogger who prepays five tools on the same day is committed for a year to all five, whatever happens to the blog.

The AI in “AI SEO tool” is sometimes extra

Six of the seven suites in this study now market some form of AI search tracking. Whether the plan a small blog would buy includes it varies widely.

• Ahrefs Lite includes 5 tracked AI prompts and 150 checks a month, where a check is one prompt run in one AI engine in one location. Fifty prompts a week in two engines needs about 433 checks a month, so we added the cheapest check pack, $50 a month for 2,500 checks. That takes a no-lock-in year from $1,548 to $2,148. Ahrefs’ pricing page and help centre describe the prompt limit differently, and we priced the cheaper reading.
• Semrush‘s $139 SEO plan does not include tracked prompts. Its $199 Starter plan includes 50, so the no-lock-in year goes from $1,668 to $2,388, an extra $720.
• Moz Pro Standard includes 50 tracked prompts, refreshed weekly, and Mangools Basic bundles its AI Search Watcher with 500 monitored prompts, across engines that include ChatGPT and both Google AI surfaces.
• SE Ranking Core lists “100 prompts to track daily”. It also sells a separate AI Search add-on that covers ChatGPT, Perplexity and Google’s AI answers, from $71.20 a month on annual billing. Its pages do not make clear which one a small blog needs, so we took the reading most favourable to SE Ranking and counted Core as enough.
• Keysearch does not offer prompt tracking. Ubersuggest includes “10 per brand / monthly” of AI search visibility with $5 add-ons for extra AI prompts. That unit does not map onto 50 prompts a week, so we left it out of this comparison.

This is the part of the bill most likely to move. Tracking AI search visibility is the newest line on these pricing pages, and the units differ from vendor to vendor: prompts, checks, dashboards, monitors. Comparing them takes more work than comparing keyword limits.

What happens when you run out

The workload above fits inside every plan we priced. A busier month may not, and the pricing pages differ sharply on what happens next. For 8 of the 16, the vendor publishes no price for using more than the plan allows. Some stop you at the limit, some move you up a tier, and two, ChatGPT Plus and Originality.ai, sell extra credits without printing the price. Jasper states no cap.

Two rules in that list change the annual bill without changing the monthly price. Originality.ai’s subscription credits expire at the end of each month even when the year was paid up front, so a quiet month’s allowance is simply lost. Clearscope’s help centre says plan add-ons are “automatically billed to your subscription if you exceed your included credit type”, though its worked example still uses older plan prices. It is the only vendor here that describes charging for extra usage without a separate purchase step.

A typical AI blogging stack, priced honestly

Roundups often recommend a stack in place of a single tool. Take a common one: Surfer for optimisation, Semrush for research, Jasper for drafting, Grammarly for editing and Originality.ai for checking. On the advertised prices it looks like $250.28 a month, or $3,003.36 a year.

Keep the freedom to cancel any of them and the same five plans cost $3,743.40 for the year, 24.6 percent above the sticker sum. Add prompt tracking in AI search, which on Semrush means its Starter plan, and the year costs $3,577.44 paid annually, nearly all of it in the week you sign up. Paid monthly it is $4,463.40, 48.6 percent above the sticker sum.

What the roundups quote

This study began as a check on “best AI tools” roundups. We read 12 of them, six each from two sites that publish them regularly, and recorded every price they quoted for the 16 tools. Of 104 price mentions, 34 named a billing term such as “billed annually”, 10 mentioned an add-on or overage, and 1 stated what a year costs: Claude Pro’s “$200 upfront”. The rest gave a monthly figure alone. We read those pages through an automated fetcher, so treat the counts as close and not exact.

A monthly figure with no term attached is the raw material of the times-twelve gap. Where the plan still exists, the figure is usually accurate as far as it goes; several quoted plans had since been renamed or repriced. Either way, it answers a question almost nobody budgeting for a year is asking.

How to price a tool before you buy it

Four checks, each of which takes a minute on the vendor’s own page:

1. Flip the billing toggle. If the big number drops when you select annual, the headline is an annual rate. Write down both.
2. Find the limit that binds. For an SEO suite it is usually tracked keywords or projects; for a writer or optimiser it is documents or credits. Check that the entry plan covers a normal month.
3. Look for “from” and “add-on”. If the feature you actually want sits next to either word, price it in.
4. Read the refund line. An annual discount is only a saving if you would have stayed the full year anyway.

We keep a dated record of these prices on our tool pricing pages and in the Blogging Tool Cost Index. The index covers the related problem of monthly prices that can only be bought a year at a time.

Method and limits

Every price was read on 30 September 2026 from the vendor’s own pricing page, help centre or other vendor-owned pages, in US dollars as printed by the vendor. Where a vendor printed two figures, we recorded both. Where a figure had to be worked out, the dataset says so; the eleven worked-out figures are listed under the main table.

The “advertised” price is the lowest per-month figure shown for the entry paid plan on the pricing page, which is the figure a roundup typically quotes. We did not count free plans, lifetime deals or discount codes. Prices exclude sales tax and VAT.

Several judgement calls could move the numbers, in both directions. Four go in the vendors’ favour:

• We counted SE Ranking Core as covering the AI prompt workload, although its separate AI Search add-on may be what a buyer needs.
• We took the cheaper of two readings of Ahrefs’ prompt limit.
• We assumed ChatGPT Plus and Claude Pro cover eight long drafts a month, because neither publishes a fixed usage number.
• We counted Mangools as meeting the weekly refresh, although it does not state how often its prompts run.

One goes against them: the workload is set at 100 tracked keywords. At 50, the Ahrefs and Keysearch gaps disappear, the total uplift across all 16 falls from 34.4 to 19.6 percent, and the median from 22.7 to 18.1 percent.

Prices change often. Our pricing pages have recorded introductory prices rising within weeks, so treat every figure here as dated.

Frequently asked questions

The questions this study answers most directly, from the dataset itself.

What is the times-twelve gap?

The times-twelve gap is the difference between a tool’s advertised monthly price multiplied by twelve and the cheapest year that covers real use without a long commitment. Across 16 AI SEO and blogging tools priced on 30 September 2026, 13 had a gap, and the median tool cost 22.7 percent more than its advertised price times twelve.

Why is the annual cost of an AI tool higher than the monthly price times 12?

For three reasons. 11 of the 16 tools advertise an annual rate that is only available if you pay for the year up front. Two have entry plans too small for 100 tracked keywords. And two SEO suites charge extra, or require a higher plan, to track prompts in AI search.

Which AI SEO tool has the biggest gap between its advertised and real price?

Ahrefs. It advertises $29 a month, but its Starter plan tracks 50 keywords. Tracking 100 needs Lite at $129 a month, which costs $1,548 over a year paid monthly and $1,290 paid yearly. The gap comes from Starter’s keyword limit, not its billing. Tracking 50 AI prompts as well adds a check pack from $50 a month.

Is it cheaper to pay for AI tools annually?

Yes. For the 13 tools where an annual price is published or can be worked out, paying yearly saves between 13 and 60 percent on the plan a small blog needs. The trade-off is the exit: several vendors refund annual plans only within a short window, and Semrush does not refund month-to-month plans at all.

Do AI SEO tools charge extra for AI search tracking?

Some do. Of seven SEO suites, Moz Pro and Mangools include prompt tracking in the entry plan and SE Ranking lists prompts in its Core plan. Semrush needs its $199 Starter plan for 50 tracked prompts, Ahrefs includes 5 prompts on Lite and sells extra checks from $50 a month, and Keysearch does not offer it.
