How much does SEO cost for a small business?
The short answer
The honest range for a small business is wide, and the number matters less than what it buys. A monthly retainer that produces reports rather than changes is expensive at any price. A one-off audit plus a few hundred pounds of actual fixes is often the better first purchase. And the cheapest SEO available to most small businesses is free: your Google Business Profile, correct hours, and pages that answer real questions.

Do the free things first
This is not a way of avoiding the question. It is that a meaningful proportion of small businesses who pay for SEO are paying somebody to do things they could have done in an afternoon, and would get a better return from doing the paid work afterwards on a fixed foundation.
Before you pay anyone:
- Claim and complete your Google Business Profile. Free, works within days, and for a local business it outperforms almost anything you can buy — see what is Google Business Profile.
- Make sure your name, address and phone match everywhere.
- Fix your opening hours, including holidays.
- Make sure your site is readable — menus and prices as text, not images.
- Ask happy customers for reviews. Free, and it moves the needle more than most paid work — see how to get more Google reviews.
If those are not done, any agency's first month is going to be doing them, and you will be paying agency rates for it.
What the brackets actually buy
A one-off audit. A fixed fee for somebody competent to tell you what is wrong. Good value, and the right first purchase for most small businesses — provided you get a prioritised list of specific fixes rather than a forty-page automated report. Ask to see a sample before you commit; the difference between a real audit and a tool export is enormous and both cost about the same.
A small monthly retainer. Typically buys a few hours a month. Realistically that is monitoring, small fixes and a report. It will not move a competitive term, and expecting it to is where most disappointment comes from. Worth it if the hours go into actual changes.
A substantial monthly retainer. Buys content production, technical work and link acquisition at a rate that can genuinely shift competitive terms. Appropriate when the value of a customer justifies it — a law firm or a clinic, not a café.
A specialist for one job. A local SEO setup, a migration done without losing rankings, a technical fix. Fixed scope, fixed fee, ends. Frequently the best value on this list and rarely offered because it does not recur.
The question that separates the useful from the expensive
Ask it in the first conversation: "What will actually change on my website, and who makes the change?"
The answers sort agencies quickly. A good one describes specific edits — these pages rewritten, these titles changed, these pages created, this fixed. A poor one describes activity: monitoring, optimisation, reporting, strategy.
The second kind of engagement can run for two years and leave your website in the state it started, because nothing in the deliverable was a change to your website. You will have bought reports.
Follow it with: "What do I own at the end?" If the changes live somewhere only they can reach, you are renting your rankings — the full argument is in should I pay someone for SEO.
The hidden cost nobody quotes
There is a line item that never appears on a proposal and often exceeds the fee: the cost of implementing what they recommend.
The audit says these twelve pages need rewriting, these titles are wrong, these hours are stale, this page needs to exist. If every one of those changes has to go through a developer, you have a second invoice and a three-week delay, and in practice the small items get dropped as not worth billing for.
That is how a three-month SEO engagement becomes a nine-month one — not because the advice was wrong, but because the loop between advice and action was measured in weeks. See how long does SEO take.
So the real question to ask yourself before buying SEO is not what it costs. It is whether you are able to act on it.
Where Helm fits
This is a case where the platform decision changes the economics of the service you are buying.
On Helm the things an SEO audit tells you to change are things you change: the page title and description on each page with character counts, the page text, the opening hours, the prices, the social preview image, and whether a page is indexed at all. The implementation cost of an audit drops close to zero, which makes a one-off audit — the best-value bracket above — actually deliver rather than sit in a folder.
It also changes what a retainer is worth buying. You stop paying for access to the ability to make changes and start paying only for the judgement about which changes to make, which is the part that was ever worth paying for.
The short version
Do the free things first, because otherwise you are paying somebody to do them. Buy a one-off audit before a retainer. Ask what will change on the site and who makes the change. And count the implementation cost, because on most arrangements it is larger than the fee and nobody puts it on the quote.
