Research exhibit / Retrofit and clean energy
Terralis
How can a visitor identify the right retrofit service and understand an estimate?
A building needs an assessment before it needs a promise.
Clean-energy optimism does not explain which service fits a building or what a savings prompt assumes. If service boundaries and estimate inputs are unclear, a visitor may request an assessment on the wrong basis.
Concept study · research not yet conducted. This is a specific investigation plan around an illustrative website. No interviews, verified search volumes, implemented software or measured outcomes are claimed.
The question shapes
the whole website.
This retrofit and clean energy direction would be useful if the visitor can answer the study’s question and the receiving team can act on the resulting information. That remains a hypothesis to test.
The proposed website responseFollow the optimistic opening with sector choices, retrofit categories and an explicitly defined estimator route. Let the selected service and site needs shape a scoped assessment request rather than leaving the calculation disconnected from delivery.

Start with people
Discuss how an owner moves from a building concern to assessment, and ask assessors which missing facts delay a useful recommendation.
The proposed record: A short list of audience needs, recurring questions and assumptions that still need checking.
Search for participants
Start with permitted enquiries and customer records, service-owner referrals and relevant professional communities. Recruit against the role and task, include different experience levels and keep an appropriate consent record.
Keep an evidence trail
Record participant criteria, research date, exact task, supporting observations and contradictory findings. An assumption is accepted, revised or rejected against what people actually do and say.

Inspect the market
Review competing offers and alternative ways to solve the buyer’s problem. Record the public promises, qualifying details and unanswered questions. Investigate whether a gap matters to the buyer before making it the message.
Make the selection auditable
Keep the query source, intent, result-page review, target page, date and owner. Volume and competition remain unknown here. A real keyword tool estimate must include its tool, geography and period; first-party search data has its own coverage limits.
One question.
A proper, useful answer.
SEO helps people find a relevant page. AEO means structuring an answer people can understand and answer systems can interpret. Both begin with factual, specific content.
Editorial sketch · facts and wording still to verify
How can a visitor identify the right retrofit service and understand an estimate?
Start with the building, its use and the information an assessor needs. Show how the assessment informs possible options, which assumptions remain open and what must happen before projected benefits can be judged.
Search foundations
A distinct title, relevant heading, readable text, useful internal links and a page that can be crawled and indexed when publicly launched.
Answer structure
Place the direct answer beside the question, then show conditions, evidence, responsible ownership and the appropriate action.
Measure each channel
Use permitted query, impression, visit and enquiry data. Review available AI-citation reports separately. A citation, a visit and an enquiry are different events.
Google describes optimisation for its generative features as SEO; it does not require a special AI file or AI-only schema. Rankings, inclusion in answers and commercial results cannot be guaranteed. This password-protected preview supplies no live search-performance evidence.
Write this business.
From the beginning.
Every published sentence should earn its place by answering a buyer’s question or explaining a verified fact. The content is developed from scratch around this brief; a generic AI paragraph cannot supply client knowledge or evidence.
Gather the real material
Explore retrofit decisions with property and commercial users. Ask which site conditions affect service selection and what assumptions they expect a savings estimate to disclose before treating it as useful planning information.
Work out what the building needs first.
Start with the building, its use and the information an assessor needs. Show how the assessment informs possible options, which assumptions remain open and what must happen before projected benefits can be judged.
Approve the meaning
The owner reviews business facts and permissions; the research team checks the connection to the buyer question; likely users test whether the answer is usable. Unverified claims stay out.

Record the conditions
Task wording, participant criteria, device, starting point, assistance, completion rule and failure reason all belong in the record. Agree them before observing the task.
Change one useful thing
Prioritise a clear barrier, make a specific revision and repeat a comparable task. Keep evidence that contradicts the hypothesis. Small usability samples reveal problems; they do not establish a population conversion rate.
The maths must match

A number becomes useful when its numerator, denominator, conditions and limitations are clear. These specifications connect the proposed measures to this case’s actual task.

- Collect
- State the success criterion first. Record successful, failed and assisted attempts; count every attempt in the denominator.
- Interpret
- Compare like-for-like tasks and report the counts as well as the percentage. A small sample does not establish a population conversion rate.

Show the calculation(8 ÷ 12) × 100 = 66.7%
No measured resultOne fictional arithmetic example: eight completed tasks out of twelve attempts. This is not a baseline, result, uplift, conversion forecast or measurement of this website.
| Measure | Completed | Attempts | Rate |
|---|---|---|---|
| Task completion | 8 | 12 | 66.7% |
This arithmetic demonstrates a method; it is not an improvement, forecast, estimate of revenue or proof of causation. A commercial claim needs suitable real data, an appropriate comparison and enough observations for its purpose.
Improve in small increments
Agree a starting measure for next-step understanding, assumption clarity, assessment readiness. Test the riskiest step first, change one clear problem, then repeat a comparable task; record other changes that could affect the comparison.

What would persuade us
to keep or change it?
Research is useful when it changes a decision. This ledger connects the claims made in the brief to evidence that would support, refine or reject them.
| Claim to investigate | Evidence to gather | Decision rule |
|---|---|---|
| Buyer profile | Discuss how an owner moves from a building concern to assessment, and ask assessors which missing facts delay a useful recommendation. | Use the profile only where the recorded examples support it; retain exceptions and unresolved assumptions. |
| Chosen phrase and intent | Compare the candidate phrases with buyer wording, permitted queries and relevant search results. | Record intent, source, date, suitable page and a reason to retain or reject each phrase. |
| Published content | Trace service statements to building assumptions, assessment requirements, dependencies and the limits of any projected benefit. | Write the answer from scratch, record factual approvals and remove unsupported claims. |
| Proposed improvement | Choose the appropriate first step for a fictional property and explain why a site-specific assessment is still needed. Check the same essential path with keyboard navigation and relevant assistive technology. | Establish a baseline, count failed attempts and compare agreed tasks before claiming any improvement. |
Published B2B research informs the questions. It does not prove this design will increase enquiries or sales.
Read the 16 sources, their scope and their limits
- 2025 B2B Buyer Experience Report (source, new tab)
Commercial B2B buyer survey
94% of surveyed buyers said they ranked their shortlist before speaking with sellers.
Nearly 4,000 buyers in North America, APAC and EMEA; qualifying purchases were at least $25,000 and the median was $200,000–$300,000.
Retrospective reports about higher-value B2B purchases; not a website experiment or a result for these fictional businesses.
- B2B Website Usability: public research overview (source, new tab)
Publisher’s public overview of its third-edition B2B research
Business websites need to support comparison, shared purchasing decisions and customer tasks after a purchase.
The public overview describes representative business users testing 293 B2B sites across the US, UK and Singapore, using several research methods.
The full paid report was not accessed. This overview does not supply a conversion estimate or validate any concept shown here.
- Learning about users and their needs (source, new tab)
Public-service research guidance
Investigate what people need to do, their current approach and the problems they experience; treat untested internal opinions as assumptions.
Guidance for government services, including people who use, provide or support them.
A transferable practice method, not a B2B commercial-outcome study.
- Creating an experience map (source, new tab)
Research synthesis and journey-mapping guidance
Combine observed user experiences to reveal stages, dependencies, pain points and handovers across a service.
Particularly relevant to journeys involving several events, people, teams or touchpoints.
The map must be grounded in research. A proposed diagram is not an observed customer journey.
- Making prototypes (source, new tab)
Design practice guidance
Explore and test alternative designs with a small prototype before committing to a full build.
Includes sketches and realistic interactive prototypes for desktop and mobile tasks.
A convincing prototype is not proof of production security, reliability, integration or business value.
- Using moderated usability testing (source, new tab)
Task-based usability research guidance
Observe likely users attempting believable tasks to uncover confusing language, layout and interaction.
Tasks should have a clear goal without revealing the answer; sessions require appropriate recruitment and a consistent discussion guide.
Small qualitative rounds reveal specific problems. They do not justify general population percentages or guaranteed conversion gains.
- Using performance data to improve your service (source, new tab)
Performance measurement guidance
Plan measurement from the beginning and combine task data with research to decide what to improve.
The government service metrics are accompanied by guidance to choose additional measures appropriate to each service.
Commercial projects need their own measures. A before-and-after change may have several causes and is not automatically causal evidence.
- Involving Users in Evaluating Web Accessibility (source, new tab)
Accessibility evaluation guidance
Testing with disabled users can reveal practical barriers; combine this with standards-based evaluation and report the review’s limits.
Covers early consultations, formal studies, assistive technology and cautious interpretation of limited samples.
One user’s experience does not represent every disability. User testing alone cannot establish WCAG conformance.
- Search Engine Optimization (SEO) Starter Guide (source, new tab)
Primary-source practice guidance
Create original, readable and well organised content; anticipate the different terms experienced and new readers may use; give related pages descriptive links and relevant images useful context.
Official introductory guidance for search discovery and presentation. Search systems can understand related language without every exact phrase being repeated.
No guaranteed ranking, indexing or snippet wording. Avoid keyword stuffing, arbitrary word counts and invented search volumes. Public discovery and search eligibility need their own checks; publication does not guarantee a ranking or AI citation.
- Influencing your title links in search results (source, new tab)
Primary-source practice guidance
Give each page a concise, descriptive and distinct title, avoiding repeated boilerplate and keyword stuffing.
Official guidance explains how Google selects search-result titles using several on-page and off-page sources.
A written title is a preference signal, not control over the exact displayed search title or a promised click-through rate.
- Creating helpful, reliable, people-first content (source, new tab)
Primary-source practice guidance
Google encourages original, useful, reliable content for an intended audience. Its current quality guidance discusses effort, originality, skill and factual accuracy, with clear attribution where appropriate.
Publisher self-assessment guidance. Google says SEO is useful when applied to people-first content rather than search-engine-first content.
This is not a universal content checklist that guarantees ranking or sales. E-E-A-T is not itself a specific ranking factor. Each word cannot be separately scientifically validated.
- Optimizing your website for generative AI features on Google Search (source, new tab)
Primary-source practice guidance
Google treats AEO/GEO work for its generative search experiences as SEO. It prioritises original, useful content and ordinary technical structure; special AI files, schema and content chunking are unnecessary.
Google Search. Eligibility includes indexing, snippet eligibility and current Search Console generative-feature inclusion settings.
No guaranteed indexing, citations, position, sales outcome or eligibility in other services.
- Introducing AI Performance in Bing Webmaster Tools Public Preview (source, new tab)
Primary-source practice guidance
Bing recommends clearer structure, evidence, expertise, accurate current information and consistent meaning across text and media. Its preview reporting shows citation activity across supported Microsoft AI experiences.
Bing, Microsoft Copilot and selected supported integrations. Citation counts and sampled grounding queries describe supported answer experiences.
The cited-page measures do not indicate ranking, authority, placement or sales. Readable answers and references do not guarantee inclusion in an AI response.
- How People Read Online: New and Old Findings (source, new tab)
Publisher’s synthesis of eyetracking research
People commonly scan online content while looking for relevant information. Reading patterns vary with layout, task, motivation and the individual.
Public summary of 13 years of eyetracking research, over 500 participants and more than 750 hours of observation.
Not every visitor scans all content, and no single layout pattern fits all pages. The public article does not establish a revenue increase for this project; the paid report was not accessed.
- Memory Recognition and Recall in User Interfaces (source, new tab)
Cognitive psychology and interface-design guidance
Visible choices and contextual cues can support recognition instead of asking people to recall information unaided.
A cognitive-psychology explanation applied to menus, search and interface content; published January 2024.
A design heuristic, not proof of universal behaviour or a specific conversion increase. Labels still need testing with the intended audience.
- Web Vitals (source, new tab)
Published web-performance measurement guidance
The published good-experience thresholds are LCP at most 2.5 seconds, INP at most 200 milliseconds and CLS at most 0.1.
Assess the 75th percentile of real page loads, separately for mobile and desktop, across all three Core Web Vitals.
These are performance targets, not measured results for the concepts. A laboratory result is diagnostic and is not equivalent to representative field data or a sales forecast.
