Costs and pricing
Part of When to plan technical SEO costs and pricing in your budget
Before you budget for technical SEO, know the hidden costs
Hidden technical SEO costs rarely arrive as one invoice. This list covers inclusion criteria, geography and a worked example in pounds, plus three sources.
What to take away
- The most common mistake is treating the audit fee as the whole cost. Hidden spend sits in engineering time, re-crawls, content rewrites and tool seats that nobody put in the budget line.
- Inclusion criteria for this listcosts that appear after a technical SEO audit has been signed off, in England, priced in pounds sterling.
- Geography matters. Rules that apply across the UK are labelled UK; anything specific to England is named as England.
- One labelling note covers the articlea figure is illustrative unless its row or sentence names a public source. The named sources are Google's canonicalisation guidance, the FTC advertising and marketing taxonomy and IAB UK guidance on ad blocking solutions, each linked where it is used.
- The £13,400 worked example below is illustrative for one assumed English ecommerce site. It is not a UK market benchmark.
- Read the full costs and budget guide before you commit a number to a finance sheet.
Where the hidden costs sit: engineering, re-crawls, tools and compliance
Engineering time after the audit lands
A crawl report is cheap to produce and expensive to action. Developer hours are the largest hidden line for most English teams, because fixes queue behind product work.
Developer hours vs tool spend
- £1,650Developer hours
- £400Monthly tool spend
For example, a team paying £400 a month for a crawling tool might need 30 developer hours to clear duplicate URLS. At an assumed internal rate of £55 an hour, that is £1,650, roughly four times the tool spend.
Duplicate URL consolidation is documented properly by Google, and the official canonicalisation guidance is the reference your engineers will follow. Budget the hours, not just the recommendation.
Re-crawls, verification and reporting cycles
Fixes need proving. Each verification pass costs crawl credits, analyst time and a reporting slot. Teams often budget one audit and forget the two or three confirmation runs that follow.
For example, a £900 verification phase across three months is common. On a large site, crawl volume pushes that higher without anyone changing scope.
Analyst time is the second half: someone has to compare before and after, usually not the person who ran the first crawl.
Commercial and compliance costs people miss
Tool seats and overlapping subscriptions
Technical SEO audit tools are usually bought per seat or per crawl credit. Hidden cost appears when a second team buys a similar tool because procurement never saw the first contract.
A stack of £250 a month for crawling, £120 for log analysis and £80 for monitoring is £450 a month, or £5,400 a year, before any human touches the data. Audit the overlap annually.
For a real UK price point, the UK vendor Screaming Frog lists its paid SEO Spider licence at £199 a year plus VAT at the time of writing. Check the vendor page, because list prices move.
The cost guide data and sources article explains how to trace each of those figures back to a named origin rather than a vendor page.
Claims, content and regulatory review
Content rewrites triggered by an audit are a hidden cost with a compliance edge. Marketing claims on rewritten pages must still stand up, and the FTC advertising and marketing taxonomy is a useful reference point when you research how regulators categorise marketing claims.
If your site carries advertising, monetisation changes can also shift revenue assumptions. The IAB UK guidance on ad blocking solutions is relevant to publisher monetisation and content strategy decisions that often follow a technical audit.
A worked example with labelled figures
One English site, six months
Assume a mid-sized English ecommerce site. Audit fee £3,500 one-off. Developer time 60 hours at £55, so £3,300. Analyst time 40 hours at £45, so £1,800. Tool seats £450 a month for six months, so £2,700. Content rewrites £1,200. Verification crawls £900.
Total: £13,400. The visible audit fee is 26 per cent of that. The rest is hidden cost that a budget sheet usually misses.
| Cost line | Illustrative? | Amount |
|---|---|---|
| Audit fee, one-off | Yes | £3,500 |
| Developer time, 60 hours at £55 an hour | Yes | £3,300 |
| Analyst time, 40 hours at £45 an hour | Yes | £1,800 |
| Tool seats, £450 a month for six months | Yes | £2,700 |
| Content rewrites | Yes | £1,200 |
| Verification crawls | Yes | £900 |
| Total | £13,400 |
How to present it to finance
Split the total into one-off and recurring. One-off here is £10,700; recurring tool spend is £5,400 a year. Finance can then compare like with like.
Label every assumption, and cite a named source with a date where one exists. That single habit prevents most budget disputes.
Common questions
Are these costs the same across the UK?
No. This listicle is written for England, and Scotland, Wales and Northern Ireland can differ on devolved matters. Check the rule that applies where your team and supplier sit.
Should I include tool costs in the audit budget?
Yes, if the audit depends on them. Seats and crawl credits continue after the report is delivered, so they belong in the recurring column.
How many verification cycles should I budget for?
Plan for at least two, and three on larger sites. Each cycle carries crawl cost and analyst time, and skipping them leaves the fix unproven.
