A new website receives almost nothing on its own. Visits have to be gone after, and in the UK as across most of Europe the overwhelming majority still arrive through one search engine. Being invisible there means giving up your main source of inbound enquiries. The question of hiring an agency usually surfaces once someone has sent you a quote.
The useful question is not whether you need SEO. It is what a provider will do with your budget, what they can honestly promise, and how you tell a serious proposal from a sales pitch. Both look alike on the first page.
What follows is the reading grid I have used for more than a decade when a director asks for an opinion before signing. Most of the decision rests on who does the work and what the contract says.
What an SEO agency actually does
The word “SEO” covers several trades that are routinely conflated. Behind one commercial proposal you will usually find five distinct workstreams.
- Technical SEO: indexing, URL structure, markup, structured data, page speed, mobile rendering, and the errors that stop a search engine reading the site.
- Content: identifying the queries your customers actually type, deciding which pages to create and which to rewrite, internal linking, keeping existing pages current.
- Authority and links: relationships with third-party sites, legitimate trade directories, partnerships, local and sector press.
- Local visibility: the business listing, consistent contact details, reviews, and pages for each area served. See our local SEO page.
- Measurement: traffic and positions, and above all the quote requests, calls and sales that follow.
Paid search, social media or email may be bundled in as well. Few organisations do all of it to the same standard, so the first question in a meeting is not “do you do SEO?” but “who here will do what, for how many hours a month, over which scope?”. You are not buying a ranking; you are buying qualified working time and a method. If nobody can tell you how many hours your retainer represents, that is already an answer.
What no provider can guarantee
Google says so itself, in the documentation written for businesses considering hiring an SEO: no one can guarantee a number one ranking in search results. The same page advises caution with providers claiming a special relationship with Google, and with offers arriving by unsolicited email, and recommends checking any significant recommendation against the official documentation first.
The contractual logic points the same way. Absent a specific, quantified commitment in the agreement, this work is an undertaking to apply reasonable professional skill and care, not to reach a given position, since the ranking depends on a third-party system the provider does not control. Read the terms with that distinction in mind, and take your own legal advice on anything unusual.
The corollary matters. An agency that writes “first page for this keyword within twelve months” has converted its commitment into a promise of results, and is exposed if it fails. That is bad for them and rarely good for you: such promises are normally made on queries with no competition, and therefore no customers.
Warning signs before you sign
- The guaranteed position. “Top three guaranteed”, “first page or your money back”. It contradicts what Google publishes, and is usually pinned to easy keywords.
- Bought links sold as link building. Google's spam policies treat buying or selling links for ranking purposes as a violation, unless they carry
rel="sponsored"orrel="nofollow". Ask for the list of linking domains, before and after. - A long tie-in with no defined deliverables. Twenty-four or thirty-six months, a monthly figure, and no description of what gets produced. A minimum term can be justified, because SEO is slow, but it needs dated deliverables against it.
- Refusal to hand over access. Accounts in the agency's name, a locked Search Console property, a site on a platform you cannot take with you.
- Reporting chosen after the fact. A position table whose keyword list changes from month to month measures nothing.
- Cold outreach, particularly when it announces “serious errors detected on your site” without having audited anything.
I also look at the references, and not the logo wall: the actual sites. A pass through Ahrefs, Semrush or Sistrix shows the organic traffic curve over three years. One client still active whose curve climbs slowly is worth more than ten prestigious logos whose sites have fallen away. Nothing stops you ringing two of them to ask what they received last month.
How SEO work is priced
| Model | What you buy | Suits you when… | Watch for |
|---|---|---|---|
| Monthly retainer | A recurring volume of hours on a defined scope | The site is live and the work is continuous | Insist on the hours and deliverables for the month |
| One-off project | An audit, a redesign or a migration, with a written report | You want a diagnosis before committing further | Check it gives prioritised actions, not a raw error list |
| Time and materials | A day rate, drawn down as needed | An in-house team exists and steers the work | Set a monthly ceiling and require a time report |
| Performance-based | A variable fee indexed to an agreed metric | Conversion tracking is reliable and shared | Define the metric, its source and the term before signing |
None is better in itself. For a small business, the healthiest mix is often a short scoping engagement first — an audit with a dated action plan — then a retainer sized on what it found, rather than the reverse.
The deliverables and access to insist on
Serious work leaves a trail. Ask for these in writing at proposal stage, not after the first invoice.
- A prioritised action plan with deadlines, revised at agreed intervals.
- A monthly report stating what was done, by whom, and what comes next.
- A stable dashboard: organic traffic, entry pages, Search Console queries, conversions. What matters is that the list of metrics does not shift with the results — the core of sound traffic management.
- The list of links obtained, with domains and dates.
- Access in your name: Search Console property, analytics account, hosting, domain name, CMS. The agency should be invited to those, never own them.
- Content and development: who holds the rights, and what you keep at the end.
On links, a paid placement stays within the rules when it is declared, which in practice means markup like this on the linking page:
<a href="https://example.com/" rel="sponsored">Partner name</a>The contract terms worth re-reading
Three clauses deserve slow reading. First, the nature of the commitment: a well-drafted contract describes the work rather than promising a rank. Second, term and renewal: check the anniversary date, the notice period and how notice must be served. Automatic renewal is where most disputes start, and consumer protections there do not necessarily extend to a company signing in the course of its business. Third, exit: does the content stay online, do rented links disappear, who keeps the accounts?
If the work is not delivered, the sequence is unremarkable: document the failures, put the provider formally on notice, then seek termination or a price reduction. Disputes are won with reports and written exchanges, not impressions. One more reason to require dated deliverables from month one.
Doing it yourself, training, or delegating
Three routes remain open, and they are not exclusive. Learning it yourself costs mainly time, and risks applying advice that expired years ago. Training brings content production in house while keeping an outside view on the technical side. Delegating makes sense when your time is worth more elsewhere.
Budget is often less of a constraint than allocation. One indication, and it is French data rather than a UK benchmark: in the France Num 2025 barometer published by the Direction générale des entreprises on 15 September 2025, 78% of small and mid-sized business leaders said digital brings real benefits to their activity, and three in four reported a specific budget for digital projects. The survey covered 11,021 businesses; the answers are self-reported.
On agency versus freelancer, geography matters less than it used to. What counts is how long they have been practising, who executes the work, whether they carry professional indemnity insurance, and what they will put in the contract. If you are weighing up several quotes, our guide on comparing providers and the evidence they offer covers the questions to ask, and the SEO services page describes what ongoing support contains.
Common questions
Can an SEO agency guarantee a first position on Google?
No. Google's own documentation states that no one can guarantee a number one ranking, and advises caution with providers claiming a privileged relationship with the search engine. A contract for this work is normally an undertaking to apply professional skill and care, not to reach a given rank.
What is the difference between an SEO agency and a freelance consultant?
An agency brings several profiles — technical, editorial, links, paid media — and absorbs larger volumes, but the person you meet is not always the one who executes. A freelancer gives you one point of contact and lower overheads, with limited capacity. The useful question is the same either way: who does the work, how many hours, and what is delivered.
Who should own the Search Console and analytics accounts?
The client business, always. Create them with a company email address and invite the provider as a user. The same applies to the domain name, the hosting and administrator access to the site. Without those in your name, changing provider becomes expensive, and sometimes impossible without starting again.
Is a twelve or twenty-four month commitment normal in SEO?
A minimum term is defensible: organic results build over months, and work stopped after eight weeks produces nothing. What is not normal is a long tie-in with no monthly deliverables described, no ceiling on hours and no exit clause. Check the anniversary date, the notice period and how notice must be served.
Does Google prohibit buying links?
Google's spam policies treat buying and selling links intended to influence rankings as a violation, along with exchanging goods or services for links. Such links remain acceptable when they carry the rel="sponsored" or rel="nofollow" attribute. A site that breaches the policies can receive a manual action, notified in Search Console.
What should you do if a provider does not deliver?
Gather the written evidence first: the proposal, reports, email exchanges, deliverables received or missing. Then send a formal notice setting out the failures and the time allowed to remedy them, before considering termination or a price reduction.
