The 8 Best SEO Agencies in Manchester

The two firms on this list that publish a number both start at £1,500 a month. Across the wider market a small to mid-sized site sits roughly between £1,000 and £3,500 a month, and a one-off technical audit runs £750 to £2,500. Enterprise and large ecommerce programmes go well past that. Add VAT to everything. Treat anything under about £750 a month with suspicion at that price nobody is doing original work, and you are usually buying an automated audit and a monthly PDF that nobody reads.

Technical fixes can move things in weeks, because you are removing blockers that already exist. New content and links take three to six months before non-brand traffic moves in a way you would notice, and six to twelve before it compounds. Local search in a thin category moves faster. National ecommerce in a competitive vertical moves slower and costs more. If an agency promises rankings inside thirty days, ask which keywords, and you will usually find they mean your own brand name. Budget for twelve months or do not start.

The content on your domain is yours. The links are nobody's, they are editorial placements on other people's sites, and they stay where they are. That is worth knowing because some agencies rent links rather than earn them, and a rented link disappears the month you stop paying, taking the rankings with it. Ask directly whether any placements are paid-for subscriptions, and ask for the full list of live links built for you. An agency that will not hand over the link list is telling you something.

If your problem is diagnosed, buy a specialist, a technical SEO for a crawl and indexation mess, a digital PR team for an authority gap, an ecommerce specialist for a catalogue. If your problem is "organic is flat and we do not know why", buy an agency with a bench that can diagnose it, then argue about who does the work. The expensive mistake is buying a content retainer to solve a technical problem, which is common because content retainers are the easiest thing to sell.

For most sites, content is the larger share and the one that compounds. A workable split on a mid-sized retainer is roughly half content and on-page, a quarter technical, a quarter authority work, but that is a starting point, not a rule. A site with an indexation problem should be spending almost everything on technical until it is fixed, and a site with excellent content and no authority is the opposite case. If an agency proposes the same split for every client, that is the finding.

Mostly repackaged, with a genuine sliver underneath. What earns a citation in AI Overviews or ChatGPT is largely what earned a featured snippet before, clear, well-structured, factually specific pages from a source the model treats as credible, with schema that makes the entities legible. Three firms on this list now sell it as its own line. The test is simple. Ask what they changed on a specific page and what happened afterwards. A real answer names a page, a change and a result. A repackaged one talks about the future of search.
