The verdict in three sentences
For a drip irrigation systems manufacturer in Manchester, twelve months of SEO cost roughly £35,000 to £50,000 as a 2026 estimate, audit and site restructure included. In our fictional example, that budget lifts distributor and grower enquiries from 10 to 34 a quarter and multiplies organic traffic by 2.5. The tipping point comes around month 9, when rewritten spec pages start ranking for the technical queries greenhouse growers actually type.
The starting point
The company in this example is fictional and representative, never a real client. Based in Trafford, it designs pressure compensating drippers, dripline, controllers and fertigation units for glasshouse tomato and cucumber growers in Yorkshire and the Lea Valley, soft fruit farms under polytunnels, and commercial nurseries. It sells mainly through horticultural distributors, but growers and their technical advisers research online before asking for a quote.
The marketing director has to convince the board. Here are the baseline and the requested budget.
| Metric or item | Baseline | 12 month budget (2026 market ballpark) |
|---|---|---|
| Organic sessions per month | 1,500 | n/a |
| Queries on page one | 10 of 55 tracked | n/a |
| Distributor and grower enquiries per quarter | 10 | n/a |
| Audit and site restructure | Organised by product range, not by crop | £8,000 |
| Rewrite of 30 spec sheets as web pages | PDF datasheets, not indexed | Included in retainer |
| Monthly SEO retainer | None | £2,900 a month, or £34,800 |
| Year one total | £42,800 |
The 55 tracked queries cover products (pressure compensating dripper, fertigation controller) and uses (drip irrigation for strawberries under polytunnel, greenhouse tomato irrigation system).
Month by month
The table follows the main milestones. Results are 2026 estimates consistent with this type of project, not guarantees.
| Period | Main actions | Organic sessions per month | Enquiries per quarter |
|---|---|---|---|
| Months 1 to 2 | Audit, crop based structure, redirects | 1,500 | 10 |
| Months 3 to 4 | 12 spec sheets rebuilt as HTML, crop pages | 1,700 | 11 |
| Months 5 to 6 | 18 more spec pages, regional grower pages | 2,200 | 16 |
| Months 7 to 9 | Growing guides, distributor locator, water efficiency pages | 3,000 | 24 |
| Months 10 to 12 | Push pages close to the top 3 | 3,750 | 34 |
The turning point is converting PDFs into HTML pages: Google finally indexes flow rates, pressure ranges and emitter spacing, exactly what growers and their advisers search for.
The payback case presented to the board
The board reasons in gross margin. Here is a simplified calculation with prudent assumptions.
| Item | Value (2026 assumption) |
|---|---|
| Extra enquiries over the year | about 1 + 6 + 14 + 24 = 45 |
| Conversion to distributor or direct order | 25 % |
| Extra orders | 11 |
| Average annual order value | £16,000 |
| Gross margin | 38 % |
| Extra margin in year one | about £66,900 |
| Return on £42,800 invested | about 1.6 times |
In year two, with no audit, the budget drops to £34,800 while new distributors reorder, so the return improves markedly.

Mini case study
Illustrative example, fictional persona: Rachel, marketing director of this Manchester manufacturer, also shows the board a cautious scenario. If traffic only doubles and enquiries plateau at 22 a quarter, the company gains about 30 enquiries, or 7 orders and £42,600 of margin. Even in that low case, year one roughly breaks even. The board approves with a review at month 6.
FAQ
How much does a year of SEO cost for an irrigation manufacturer in Manchester?
The 2026 market ballpark is £1,800 to £4,000 a month, plus £5,000 to £12,000 for audit and restructure. Our fictional example totals £42,800 in year one.
Should we turn PDF datasheets into web pages?
Yes, it is often the most profitable move: Google reads an HTML spec page far better than a PDF. Plan 25 to 40 pages for a range like this one.
When do results show?
First effects usually appear around months 5 or 6, the clear gain around month 9. Hold a formal review at month 6.
Should we create pages for Ireland and the Netherlands?
If more than 15 % of sales come from abroad, yes, starting with the 10 best selling products. Dutch pages should be written or reviewed by a native speaker.
How do we present SEO to a board?
Show a cautious and a target scenario, priced in enquiries and margin rather than rankings. In this example, even the cautious case roughly covers year one.
