Cheapest AI SEO software
Cheapest by sticker price is easy to rank. Cheapest for the job you need is the real question, because the wrong cheap tool is the most expensive of all.
Cheapest by entry price
| Tool | Entry price | What you get cheap | Watch out for |
|---|---|---|---|
| Ahrefs | $29/mo (free plan) | Backlink and keyword data | It is research, not content produced |
| Surfer SEO | from €49/mo | On-page scoring | You still write and publish |
| Writesonic | from $79/mo | AI writing, visibility tracking | Not a full plan-to-publish autopilot |
| Sorank | from $99/mo | Content produced, published, native GEO | A card is required to start the trial |
| Outrank | $99/mo | High article volume | Volume over per-page optimisation |

Cheap by price versus cheap by result
The lowest number wins only if the tool does the job you have. Ahrefs at $29/mo is a bargain for data, but if you need content produced, it is $29 spent on a problem you did not have. An autopilot at $99/mo looks pricier until you compare it to a freelancer's monthly output, at which point it is the cheap option. Price the outcome, not the plan.
