The verdict in three sentences
For a funded B2B software company in London, a good SEO partner works on the queries that come before a demo (alternatives, integrations, comparisons, compliance) rather than on top-of-funnel traffic volume. London market rates in 2026 run from roughly 450 to 850 GBP a day for an independent consultant to 4,000 to 12,000 GBP a month for a SaaS specialist agency. The two most expensive red flags are reports with no pipeline in them and content claiming a security certification you do not hold.
Pricing models in London in 2026
The ranges below come from typical London agency quotes and public agency rate pages. They are ballpark figures, not rate cards.
| Format | 2026 ballpark | What it usually covers | Limit to know |
|---|---|---|---|
| Independent consultant, day rate | 450 to 850 GBP / day | Strategy, technical audit, coaching the marketing team | Little production capacity |
| Technical and content audit | 4,000 to 15,000 GBP | Crawl, architecture, competitor analysis | Produces nothing on its own |
| Generalist agency retainer | 2,500 to 5,000 GBP / month | Technical work and a few pieces of content a month | Often unfamiliar with the B2B sales cycle |
| SaaS specialist agency retainer | 4,000 to 12,000 GBP / month | Strategy, content, editorial links, pipeline reporting | Commitments often 6 to 12 months |
| Content production per piece | 350 to 1,000 GBP / article | Expert articles, comparison pages | Highly variable quality |
| Site migration project | 5,000 to 20,000 GBP | Redesign, CMS or domain change | Plan it before any launch |
A Series A round often funds a marketing team of three to six people; in that case, a senior consultant a few days a month plus in-house writing sometimes costs less than a full retainer. At Kolonell, SEO work is on quote, scoped after a diagnosis of your site and your pipeline.
Six red flags specific to funded software companies
An IT director or finance lead evaluating your software reads your security pages and case studies with a buyer's eye. A provider who ignores this context can create commercial and regulatory risk.
| What you hear | What it reveals | Concrete risk |
|---|---|---|
| "We'll get you to the top for your main keyword" | No serious provider promises a ranking | Distorted expectations at board level |
| "Pack of 30 links a month included" | Link buying at scale | Penalty, links outside the software sector |
| "We manage Search Console on our side" | Data held by the provider | Loss of history if they leave |
| "The report tracks rankings and traffic" | No link to demos and pipeline | Impossible to justify the budget to investors |
| "Let's add a SOC 2 page to capture the query" | Ignores which certifications you actually hold | Misleading claim to buyers |
| "18-month commitment, no exit" | Rent-seeking rather than performance | Budget frozen even if strategy changes |
On regulation, your demo forms and email campaigns fall under the UK GDPR, the Data Protection Act 2018 and the PECR rules on cookies and electronic marketing, overseen by the ICO. If your software touches payments or credit, some content may amount to a financial promotion subject to FCA rules. Aim for WCAG 2.2 AA as well, consistent with expectations under the Equality Act 2010. This is not legal advice.
Questions to ask and a grid to compare
Questions that separate candidates quickly:
- Which pages do you prioritise: competitor alternatives, integration pages, role-based pages, compliance content?
- How do you connect an organic visit to a booked demo and then to an opportunity in our CRM?
- Who technically reviews product and security content, and how fast?
- How do you stop programmatic pages (one page per integration) from becoming thin content?
- What do you hand over if we stop at 6 months?
| Criterion | Weight | Question to ask yourself |
|---|---|---|
| Understanding of the B2B sales cycle | 25% | Do they talk demos and opportunities, or only traffic? |
| Quality of the 90-day plan | 20% | Is the plan dated and costed? |
| Rigour on security and compliance content | 20% | Do they check what you actually hold? |
| Data transparency | 15% | Do accounts stay in your name? |
| Technical delivery capacity | 10% | Can they work with your developers? |
| Contract terms | 10% | Can you cancel at 3 months? |
A serious provider's first 90 days

Weeks 1 to 4: technical audit, query mapping by buying stage, connecting Search Console and the CRM to track demos. Weeks 5 to 8: fixing technical priorities, reworking product and pricing pages, first integration or comparison pages. Weeks 9 to 13: a first report linking impressions, demos and opportunities, then the next quarter's plan. Effects on competitive queries tend to arrive between 6 and 12 months.
Mini case study
Illustrative example: Ledgerline, a London maker of account reconciliation software, average annual contract of 18,000 GBP. It compares a specialist agency at 7,000 GBP a month (84,000 GBP a year) with a consultant at 700 GBP a day, 4 days a month, plus 2 in-house articles, or 33,600 GBP a year. With a 20% close rate on qualified demos, it takes 5 qualified organic demos for 1 contract. The agency pays for itself from 5 contracts a year (84,000 / 18,000 = 4.7), around 25 demos; the consultant from 2 contracts (33,600 / 18,000 = 1.9). The right choice depends on in-house production capacity.
FAQ
Should we hire a SaaS specialist or a generalist agency?
For a 3 to 9 month B2B sales cycle, an agency that speaks pipeline and demos saves time. A generalist at 2,500 to 5,000 GBP a month can be enough if your marketing team owns the strategy.
How long before we see an effect on demos?
The first organic demos can appear within 3 to 6 months on niche queries such as integrations. On category queries, expect 6 to 12 months, with no certainty of position.
Can we publish case studies for SEO?
Yes, only with real customers who have given written consent, and figures they approve. Two or three solid studies are worth more than ten vague testimonials.
What if we do not hold SOC 2 or ISO 27001 yet?
Describe your security practices honestly and any certification timeline. A factual security page of 800 to 1,200 words reassures more than an unverifiable claim.
How does Kolonell price SEO for a software company?
SEO work is on quote, after a diagnosis of the site, demo tracking and product pages. The quote sets out scope, duration and metrics.
