RSE SEO Pillar Strategy 2026

Overview & How to Read
RSE SEO Pillar Strategy 2026

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.

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.

About this analysis

This section covers a list of possible industry keyword terms provided by Gary Callachan as part of RSE's internal business intelligence process. We've gathered Ahrefs search volume and difficulty data for each term, and provided suggestions on where they could be included across the site.

These are not requirements - they are reference suggestions to support the broader content strategy. Use your own judgement on which, if any, are worth prioritising.

Top 5 priority additions - verified Ahrefs data

  1. Planned Preventative Maintenance - 600/mo, KD 0, £4 CPC. Best keyword in the entire BI list. Add to Asset Management immediately.
  2. Reverse Osmosis Systems - 200/mo, KD 5, traffic potential 5,400. Add to Water Treatment as priority cluster.
  3. DfMA - 900/mo, KD 12. Should be a standalone cluster page, not just a mention. Cross-links to all 6 pillars.
  4. Electrical Control Panels - 150/mo, KD 0. Missing from original Control Systems plan. Add immediately.
  5. 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.

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.

Stephen S Keywords - Asset Management

Ahrefs-validated review of Stephen Slessor's Asset Management keyword suggestions · 19 keywords · Business / SEO alignment analysis

Stephen Slessor's keyword list · Ahrefs validated

Stephen provided 19 keywords he believes describe RSE's Asset Management service lines. Every term has been validated through Ahrefs, mapped to the existing six-pillar structure, and classified as either an SEO page target, an H2 section, or sales/service language.

Headline finding: strong alignment between the business team and the SEO strategy. Twelve of Stephen's nineteen topics are already covered across the dashboard. Two genuine new opportunities emerged - DSEAR assessment (1,600/mo, KD 0) and OT security (600/mo, KD 4). Five terms are valid service/sales language rather than SEO targets.

Valid sales language, not SEO
How Stephen's keywords fit the strategy

Stephen's terms represent real buyer language and valid service descriptions. SEO targeting requires mapping that language to the phrases people actually type into Google - and the two aren't always the same. Every term in this review has been placed at one of three levels:

1. SEO page targets Anchor a URL and H1 around the term. Real search volume, realistic KD.
2. Body copy & H2 sections Use naturally within a page targeting a broader parent keyword.
3. Sales / service language Perfect for page copy, brochures, proposals - but not how people search.

New cluster page briefs
Two briefs from Stephen's list - both sit in the Asset Management pillar

DSEAR assessment is a net-new cluster page. OT security is a term swap that reshapes the existing Cyber Security cluster. Each brief provides URL, page structure, word counts, and internal links.

InformationalCompliance1,100–1,400w
Why this matters: DSEAR (Dangerous Substances and Explosive Atmospheres Regulations 2002) applies to every water treatment site with chemical dosing, biogas, confined spaces, or methane risk. 1,600/mo UK volume at KD 0 is the single largest keyword opportunity surfaced in Stephen's review - and aligns directly with his DSEAR & ATEX page target.

Note for writer: KD 0 at 1,600/mo is a rare opportunity - write comprehensively. Anchor on "DSEAR assessment" in H1, URL and first 100 words. Include one definition block (for AI extraction), one zoning explainer (for technical authority), one water-industry examples section (for topical relevance). This page should rank quickly and drive high-intent compliance enquiries.
InformationalCommercial1,000–1,250w
Term swap recommendation: The Cyber Security cluster currently targets "cyber security operational technology" (80/mo). "OT security" (600/mo, KD 4, £2.76 CPC) is 7.5× the volume for the same underlying topic. Swap the primary H1 and URL target - this is the single largest uplift available to the existing cluster without adding a new page.

Note for writer: Audience is water-utility operations and security leads (not general IT). Lean technical. Use "OT security" in H1, URL, first 100 words and first H2. Keep "cyber security operational technology" as an H2 or alternate phrasing so the original 80/mo variant is still captured. This should be treated as a swap - retire the old URL only once the new page has indexed and ranked.
What this means

Stephen's instincts about what Asset Management does for water clients are right - he's pointed at real buyer needs across every cluster. SEO's job is to translate that language into the exact phrasing Google search traffic actually exists around. Both sides are aiming at the same audience; the difference is just how the question gets typed. Two genuine wins come out of this review (DSEAR assessment, OT security) and the rest validates that the dashboard is already pointed in the right direction.
