Prices vary enormously and nobody can quote you a real number without seeing your site. What you can decide in advance is what you are buying, and what would make an offer a bad one.

What does SEO cost?

There is no standard price, because the work is not standard: an agency may be fixing technical faults, writing content, earning links, or all three, and the amount needed depends entirely on the state of the site and the competition. What matters more than the number is what you get for it — ask for the specific deliverables and the reporting, not a package name. Any quote given without looking at your site is a guess dressed as a price.

The four common models, and what each is honestly good for:

  • Hourly or per-project. Suits a defined job — a technical audit, a migration, fixing what a scan found. Easy to judge, because there is a finished thing at the end.
  • Monthly retainer. Suits ongoing content and competitive work. The risk is paying for months in which nothing much happened, so it needs deliverables written down, not just hours.
  • Performance-based. Attractive and harder than it looks. Everything depends on what counts as the result: rankings can be gamed with obscure queries, and traffic can be bought. Enquiries are the honest measure and the hardest to attribute.
  • Bundled with a website build. Often the weakest, because "SEO included" tends to mean a plugin was installed. Ask which specific things were done.

Is it worth paying for SEO?

It is, when the basics are already in place and the work is competitive rather than remedial. Paying professional rates for someone to find a stray noindex tag or write missing page titles is poor value, because those are afternoon jobs you can do or automate. Paying for judgement about a competitive market, and for the sustained writing that follows, is a different proposition.

This is the single most useful thing to understand before spending anything. Much of what gets billed as SEO is remedial: a blocked page, a broken sitemap, missing titles, a site that does not render for crawlers. Those faults are findable automatically, and they are the ones with the largest and fastest effect. Clearing them first means you hire for strategy rather than paying strategy rates for maintenance — and it makes the agency's job start from a working foundation.

What should I be careful of when hiring an SEO agency?

Guaranteed rankings are the clearest warning, because no supplier controls the competition or the algorithm. Be equally wary of anyone offering to pay Google for better organic placement, which is not a thing that exists, and of reports that show only rankings rather than impressions, clicks and enquiries. A good agency will happily explain what they will do and how you will know it worked.

Two more that come up often. Anyone who will not let you own your Google Search Console and analytics accounts is creating a dependency rather than a service. And a report full of "average position improved" without impressions beside it can hide a decline — the number moves when you lose visibility on a query you ranked badly for, which is not an improvement. The trap is explained in the Search Console guide.

Can I do SEO myself?

The foundations, yes, and they are usually where the largest gains are. Setting up Search Console, removing anything that blocks indexing, giving every page its own honest title and description, and answering customers' real questions in plain language are all within reach of a non-specialist. The parts that genuinely benefit from experience are competitive strategy and sustained content.

The practical route is to find out what is actually wrong before deciding what to buy. TrustCtrl produces exactly that list: the remedial faults, named page by page, with the evidence behind each one. Whether you then fix them yourself or hand the list to an agency, you are negotiating with the facts in front of you rather than a brochure. What the traffic is worth once it does arrive is a separate sum, and it is in what your SEO is actually worth in money.

What to do first, in order of return, is in how to rank higher on Google. What the whole discipline covers, including the AI half, is in SEO and GEO optimisation explained.
