Best Content Optimization Tools in 2026
Two of these grade a draft against SERP terms and bill by seat. The rest are a free plugin, a free console or a WordPress plan in euros.
Surfer yearly: Discovery $49, Standard $99, Pro $182, Peace of Mind $299 per month. Frase yearly: Starter $39, Professional $103, Scale $239 per month (monthly is $49 / $129 / $299). Rank Math PRO is €8.99 a month billed annually (ex VAT), less during first-year promotions. Google Search Console is free. Rank Math's free plugin covers on-page basics without a grader.

- 5 tools compared: Surfer, Frase, Rank Math, Google Search Console, Google Keyword Planner
- Frase (best for: Teams that want research briefs and an optimizer in one login): From $39/mo (Starter, billed yearly; $49 monthly); extra seats $29
- Rank Math (best for: WordPress sites that need schema, sitemaps and on-page SEO checks): Free plugin; PRO €8.99/mo billed annually (ex VAT), first year often discounted
- Google Search Console (best for: Seeing the queries you already get, before you buy a grader): Free; you need to verify the property
Content optimization tools look like one job: make the page rank. They bill as two. Graders sell a content score against the current SERP. Plugins sell schema, sitemaps and a traffic light in WordPress. Search Console sells nothing and still has the query data the graders are guessing at.
A comparison that treats Surfer's $99 and Rank Math's €9 as the same product is how a writer pays for a score they never needed, or a site owner buys a grader and still has no Search Console property.

Surfer
The grader most teams mean: $99 a month on yearly Standard for the editor they actually use.
- Pricing
- From $49/mo (Discovery, billed yearly); monthly billing is higher
Best for: Writers who want a content editor scored against the current SERP
Pros
- Content Editor is still the default "make this rank" workflow
- Yearly Standard at $99 is the plan people actually stay on
- SERP-based terms beat a generic keyword density plugin
Cons
- Discovery at $49 is easy to outgrow the week you need real article volume
- A score is not a strategy. Thin pages still fail
Frase
Briefs plus an optimizer. Yearly Starter is $39, and extra seats are $29.
- Pricing
- From $39/mo (Starter, billed yearly; $49 monthly); extra seats $29
Best for: Teams that want research briefs and an optimizer in one login
Pros
- Research and the draft live in one tool, which Surfer splits more often
- Yearly Starter at $39 is cheaper than Surfer Discovery if the caps fit
- Extra seats are a published $29, not a hidden quote
Cons
- Starter caps will bounce a real editorial calendar onto Professional
- Monthly is $49 / $129 / $299, so the yearly discount is the real price
Rank Math
The WordPress SEO plugin. Free works. PRO is €8.99 a month billed yearly.
- Pricing
- Free plugin; PRO €8.99/mo billed annually (ex VAT), first year often discounted
Best for: WordPress sites that need schema, sitemaps and on-page SEO checks
Pros
- Free plugin covers the on-page basics most sites actually need
- PRO at €8.99 a month yearly is a site cost, not a writer seat
- Schema and sitemaps are the job, and it does that job
Cons
- It is WordPress. Other CMSs need something else
- Content AI on paid plans is not the same product as Surfer's editor
Google Search Console
The free query log. Every paid tool is guessing at what this already shows.
- Pricing
- Free; you need to verify the property
Best for: Seeing the queries you already get, before you buy a grader
Pros
- Actual impressions and clicks, not a model of the SERP
- No seat and no article cap
- The first place to look when a page "should rank" and does not
Cons
- It does not score a draft or write a brief
- Data lags and samples on large properties
Google Keyword Planner
Free demand data. Coarse, and still better than inventing a keyword.
- Pricing
- Free with a Google Ads account; you do not have to run ads
Best for: Checking whether a topic has demand before you open Surfer
Pros
- No subscription
- Good enough to kill a topic that has no searches
- Sits next to Search Console in a sane workflow
Cons
- Ranges, not exact volumes, on a quiet Ads account
- It is not an optimizer
What it is
A content optimization tool either scores a draft against terms competitors already rank for, or implements on-page SEO on the site that publishes it. Surfer and Frase are graders with research around them. Rank Math is a WordPress plugin that happens to sell Content AI on paid plans. Search Console is the click-and-impression log from Google. They stack. They do not replace each other.
Why it matters
The meter on the paid graders is seats and articles, not traffic. A $99 Surfer Standard seat that one writer uses on ten drafts a month is a different invoice from Rank Math PRO at €8.99 covering the site. Buying both without Search Console is the usual waste: you optimize for a model of the SERP and never look at the queries you already get.
Key features to look for
Pricing
Surfer, Frase and Rank Math publish list prices, checked 25 September 2026, while Google Search Console and Keyword Planner are free, so nobody here is quote-only. Surfer and Frase charge per seat, and yearly billing is lower than monthly, while Rank Math charges per site in euros, ex VAT, and first-year promotions sometimes undercut the standard rate.
The cheapest credible entry is free, and the cheapest paid plan is Rank Math PRO at €8.99 a month billed annually, less during first-year promotions. Among the graders, Frase Starter is $39 a month on a yearly plan and Surfer Discovery is $49.
The bill jumps at Frase Scale and Surfer Peace of Mind, and again on Frase monthly billing or a $29 extra seat.
| Plan | Price | Best for |
|---|---|---|
| Surfer Discovery | $49/mo, billed yearly | Lowest yearly rate; monthly billing costs more |
| Surfer Standard | $99/mo, billed yearly | Yearly rate; monthly billing costs more |
| Surfer Pro | $182/mo, billed yearly | Yearly rate; monthly billing costs more |
| Surfer Peace of Mind | $299/mo, billed yearly | Highest listed yearly rate; monthly costs more |
| Frase Starter | $39/mo yearly ($49 monthly) | Caps push a full calendar onto Professional |
| Frase Professional | $103/mo yearly ($129 monthly) | The step up when Starter caps run out |
| Frase Scale | $239/mo yearly ($299 monthly) | Highest Frase plan, yearly or monthly |
| Frase extra seat | $29 extra seat | Published price for an extra seat |
| Rank Math PRO | €8.99/mo billed yearly ex VAT; first-year promos vary | Paid site plan; a free plugin also exists |

The bottom line
Use Google Search Console and Keyword Planner first. They are free. Add Surfer Standard at $99 a month yearly when a writer needs a SERP-scored editor, or Frase yearly Starter at $39 if briefs matter more than the Surfer editor. Put Rank Math on WordPress (free, or PRO at €8.99 a month yearly) for schema and on-page. Do not buy a grader to replace Console.
