How to use this report
1
Reading keyword data
All keyword volumes and difficulty scores are live from Ahrefs (UK, monthly) where shown with the Ahrefs badge. SE Ranking verified data is shown for Chemical Solutions keywords where available. "No data" means the keyword returned no Ahrefs result - not zero searches.
2
Reading the charts
X-axis = keyword difficulty (0–100, lower = easier to rank). Y-axis = monthly UK search volume. Bubble size = CPC value (higher CPC = more commercially valuable audience). The ideal target sits low-right: decent volume, easy to rank.
3
How pillars and clusters work
Each pillar is a comprehensive 2,500–3,500 word page targeting the primary keyword. Cluster pages (800–1,500 words) target specific sub-topics and link back to the pillar. This internal link structure builds topical authority over time.
4
Why search intent matters
Ahrefs data shows all RSE pillar keywords are informational intent - searchers are researching before they contact anyone. Pages must lead with expertise and education. Commercial conversion happens at the end of an informational journey.
5
Putting volume in context
These are niche B2B infrastructure keywords. Monthly volumes of 50–300 are normal - the audience is small, specialist, and high-value. One converted lead from organic search can represent a multi-million pound contract. Volume is not the primary success metric.
6
On-page briefs explained
Each pillar has a clickable page brief showing the recommended H1–H3 structure, word count targets, internal link map, and AI citation notes. These briefs are ready to hand to Jayne for content creation.

Live data showing what rsewater.com currently ranks for. Most traffic is brand-term driven - non-brand SEO is the opportunity.

| ross-shire engineering | 1 | 250 | 57 | Brand |

| ion exchange | 33 | 350 | 0 | Water Tmt |
| chemical dosing | 37 | 150 | 0 | Chem Sol |
Key finding: 96.2% of all organic clicks are brand-term driven. The /water-treatment/ page receives 2,511 impressions per month but only 6 clicks because it ranks at position 13.8. Ranking page 1 at those impression volumes would mean approximately 500-700 clicks/month from that page alone. The SEO pillar strategy is the mechanism to unlock this.

Keyword strategy note
"Wastewater treatment" (singular, no "solutions") gets 800/mo at KD 7 - this is 13x the volume of "wastewater treatment solutions" (60/mo) at the same difficulty. The broader term's SERP is dominated by water utilities and Wikipedia - informational intent that RSE can compete with. Recommend using "wastewater treatment" as the pillar H1 keyword and "wastewater treatment solutions" as a title tag variant for commercial intent.

Keyword strategy note
"Water asset management" (100/mo, KD 0) has double the volume and confirmed zero difficulty vs "asset management water industry" (50/mo, no KD data). Both target the same audience. Recommend using "water asset management" as the pillar H1 keyword - it is shorter, easier to rank, and has higher search demand. The SERP is weak (pos 1 is DR 23) making it highly winnable.

Action required - additional keyword research needed
Asset Management has the most complex cluster structure (3 levels per the slide). The primary keyword "asset management water industry" returns 50/mo from Ahrefs but many sub-cluster keywords (DSEAR, statutory maintenance, digital transformation, equipment hire) need SE Ranking or further Ahrefs lookups to verify volume. Recommend running these through SE Ranking as a batch before committing to cluster page priorities.

Strategic note on pillar keyword choice
"Nature based solutions" has 600/mo volume but KD 41 - dominated by government, academic, and NGO content. RSE cannot compete for this term directly. The strategy is to target low-difficulty cluster keywords (constructed wetlands KD 12, SuDS KD 11) and build topical authority, which eventually supports ranking for the broader term. The pillar page title should reflect RSE's specific angle, not the broad term.

Pillar keyword note
"Control systems" as a standalone term is highly competitive (industrial automation, IT, manufacturing). The strategy is to target water-specific and sector-specific cluster keywords (low voltage switchgear, SCADA water treatment, motor control centres) where competition is lower and RSE's expertise is directly relevant. The pillar page anchors the topic; cluster pages capture the traffic.

- Systems Integration - 400/mo, KD 14, £2.50 CPC. Highest non-brand volume in Control Systems. Needs dedicated page.
Needs its own page
Sufficient UK volume and low enough difficulty for RSE to rank. Should be the H1 / URL of a dedicated page integrating directly into the six-pillar architecture.
Use in body copy
Real industry terminology with some volume but too low to justify a standalone page. Use in copy, H2 sections, FAQ blocks and meta descriptions. Valuable for topical depth and AI citation.
Too competitive now
High KD (40+) dominated by government, universities or global brands. Use in brand narrative and PR - not as SEO page targets. Reassess in 12 months once domain authority grows.
Not how people search
Genuine industry terms useful for demonstrating expertise in body copy - but should not anchor any page title, URL or H1. Several RSE BI terms fall here - flag to business intelligence team.
High traffic potential
Some keywords show high traffic potential despite modest volume - meaning the parent topic drives much more traffic. Prioritise these even when headline volume looks low. RO Systems (TP 5,400) is the best example.
High commercial value
High CPC (£3+) indicates a commercially valuable audience even at low volume. In B2B water infrastructure, 30/mo at £6 CPC (Predictive Maintenance IoT) is worth far more than 300/mo at £0.50 CPC.

Body copy, FAQ and technical terminology - no standalone page needed
These are genuine industry terms that add topical depth and AI citation value - but none should anchor a page title, URL or H1. Use throughout body copy, FAQ sections and meta descriptions to signal expertise.
| Term | Vol/mo | Reason | Best use |
|---|---|---|---|
| Nanofiltration (NF) Systems | 0 | Zero volume | Technical body copy in Membrane Filtration cluster. H3 comparison table alongside UF, MF, RO. |
| Ceramic Membrane Filtration | No data | No data | Technical differentiator mention in Membrane Filtration cluster. Good for AI citation as specific expertise signal. |
| Zero Liquid Discharge (ZLD) | 10 | Too low | FAQ in Water Recycling cluster. "What is ZLD?" is a good AI extraction target despite low volume. |
| Activated Sludge Systems | 0 | Zero volume | H3 within Biological Treatment cluster. Comparison: activated sludge vs MBR vs MBBR. |
| Fluoridation | 0 | Zero volume | Brief mention in Drinking Water Treatment cluster. DWI regulatory context. |
| Ammonia Removal / Total Nitrogen / Corrosion Inhibition / Solids Removal | 0-10 | Zero/too low | Technical body copy across Biological Treatment, Nutrient Neutrality and Chemical Solutions pages. |
| Chemical Pipework / Air Treatment / Timber Kiosks | No data | Product descriptors | Service/product lists within Chemical Solutions pages. Not search terms. |
| Water Treatment Maintenance Services / Commissioning / Regulatory Compliance | No data | No search data | H2 section headers in Asset Management pages. FAQ: "Does RSE provide commissioning support?" |
| Performance Optimisation / Turnkey | 0 | Zero volume | Brand narrative and service description copy only. "End-to-end" performs better as a phrase. |
| DfD / DfA (Design for Disassembly / Assembly) | No data | No data | Technical mention on DfMA page as part of the full design philosophy framework. |
| Modular Construction (water context) | No water data | Too broad | H2 section within DfMA and Offsite Construction pages. Not a standalone target. |
| Standardisation / Standard Products / Lean Manufacturing | 0-10 | No/low data | Manufacturing process body copy on DfMA and Offsite Construction pages. |
| Pilot Plants | 30 | Low volume | H2 section on Modular Water Treatment page. £1.60 CPC suggests commercial audience worth noting. |
| Water Quality (broad) | 450 | KD 43 | Use throughout body copy as a natural phrase. "Water quality monitoring" (KD 1) is the rankable variant. |
| Urban Regeneration | 900 | Low CPC (£0.35) | H2 section on NbS page only. 900/mo but CPC too low to justify standalone targeting. |
Note for RSE business intelligence team: Several suggested terms return zero UK monthly search volume on Ahrefs - including Nanofiltration Systems, Activated Sludge Systems, Turnkey Water Treatment, Timber Kiosks, Chemical Pipework Systems, DfD and DfA. These are valid industry terms and right for body copy and technical documentation - but they are not how customers search. This distinction is worth calibrating expectations around.
