- Published SEO retainers run £185-£1,967/month - a local package sits at the bottom, and full retainers from agencies that list prices start around £1,000

- B2B lead gen works differently - Sopro delivers sales-qualified leads via outreach rather than driving website traffic

ClickSlice EDITOR’S PICK
ClickSlice has built its reputation on measurable ROI for SMEs. Their standout offering is GEO/LLM optimisation – positioning your business to appear in AI-generated search answers (ChatGPT, Google AI Overviews, Perplexity), not just the traditional 10 blue links. This matters because AI answers are capturing an increasing share of search traffic.
Their 24/7 performance dashboard lets you monitor rankings, traffic, and conversions in real time – no waiting for monthly reports. For e-commerce businesses, they offer conversion rate optimisation alongside SEO, connecting visibility to actual revenue.
Best for: SMEs with SEO budgets of around £1,000–£2,000/month (where full retainers sit among UK agencies that publish prices) who want SEO that adapts to AI search trends. ClickSlice’s recent case studies skew toward established e-commerce brands, so confirm SME fit on the discovery call.
PPC Geeks
If your business runs on Google Ads and Google Shopping, PPC Geeks is the specialist to consider. As a Google Premier Partner (a status Google gives only to the top 3% of participating companies in each country, reviewed annually), they can be invited to dedicated Google account support that standard partners do not get.
Their free PPC audit analyses your current campaigns and identifies wasted spend before you commit to a retainer. Data-driven bidding strategies optimise for conversions rather than clicks, meaning your ad budget works harder. For e-commerce businesses, their Google Shopping expertise can directly increase revenue from product listing ads.
Best for: E-commerce SMEs spending £2,000+/month on Google Ads who need expert management to maximise ROAS.
Sopro
Sopro takes a fundamentally different approach to the other agencies on this list. Rather than driving traffic to your website, they go directly to your ideal prospects via managed email outreach and LinkedIn engagement. Every lead delivered is a sales-qualified lead (SQL) – someone who has responded positively and is ready for a sales conversation.
This makes Sopro ideal for B2B businesses in technology, legal, accountancy, and consulting where the sales cycle is longer and lead quality matters far more than lead volume. Their team handles the entire process: prospect identification, message crafting, campaign management, and response handling.
Best for: B2B professional services firms that need a steady pipeline of qualified prospects without building an internal outreach team.
Odyssey New Media
Odyssey New Media is the best option for SMEs that want one agency handling SEO, PPC, and web development under a single retainer. Based in Birmingham, they combine local SEO expertise with national reach – and their pricing undercuts London-based agencies significantly.
Their integrated approach means your SEO, paid ads, and website all work together rather than being managed by separate teams with conflicting priorities. Technical audits identify site issues that hold back both organic and paid performance. For SMEs that have been burned by agencies delivering siloed reports without actual business impact, this joined-up approach is refreshing.
Best for: SMEs with £1,500–£5,000/month budgets who want comprehensive digital marketing without managing multiple agencies.
How Much Do Digital Marketing Agencies Cost?
Most UK digital marketing agency retainers are quoted individually, so the firmest numbers come from agencies that publish price lists. Among those, SEO retainers run from £185/month for a local package to £1,967/month for a full retainer, and PPC management starts at £145–£1,200/month depending on the agency, rising with your ad spend. Multi-channel and enterprise retainers are almost always priced on request.
| Service | Published Monthly Cost | What You Get |
|---|---|---|
| SEO | £185–£1,967 | Keyword research, on-page optimisation, link building, reporting |
| PPC Management | £145–£1,200 entry tier | Campaign setup, bid management, reporting (excl. ad spend) |
| Content Marketing | Usually quoted; one published retainer £2,967 | Blog posts, whitepapers, case studies, SEO content |
| Social Media | Usually quoted individually | Content creation, scheduling, community management |

How to Choose the Right Agency
Match your primary goal to the right agency type: SEO for organic growth (ClickSlice), PPC for immediate sales (PPC Geeks), lead gen for B2B pipelines (Sopro), or full-service for multi-channel (Odyssey New Media).
- Define your primary goal: Are you trying to rank organically, drive immediate paid traffic, generate B2B leads, or cover all bases? This determines which agency type you need.
- Set a realistic budget: Published prices give you a floor of about £1,000/month for a full SEO retainer and £145–£1,200/month for PPC management before ad spend. Budgets well below those buy a narrow, single-channel service.
- Check their specialism: Generalist agencies spread thin. Specialists like PPC Geeks (PPC only) or Sopro (lead gen only) go deeper in their domain.
- Ask for case studies: Look for results with businesses similar to yours – same size, same sector, same budget level.
- Verify pricing transparency: Any agency unwilling to clearly explain their pricing model is a red flag.
For most UK SMEs spending under £2,000/month, a single-channel specialist (SEO or PPC) delivers better results than a generalist trying to cover everything with a limited budget.
