Goal and Impact
Challenges
Search & Keyword Misalignment
They had lost all previous search equity when another agency rebuilt the Holder Parlette website. They were ranking poorly for broad, competitive keywords such as “architectural firm” or “Bay Area architect,” which generated low-value traffic from students and casual researchers rather than qualified prospects.
Portfolio Content Limitations
While Holder Parlette’s project portfolio was visually stunning, it was text-light and lacking focus keywords. As a result, the most valuable section of their site was virtually invisible to search engines.
Bandwidth and Headroom
Holder Parlette is a busy firm. Because internal stakeholders had limited bandwidth for review and QA, Perfect Thirds needed to operate with maximum autonomy.
Solution
A Measured Timeline
To avoid the steep costs and internal resource drain of a rushed timeline, we implemented a phased, incremental approach.
Transitioning Portfolios to Regional Hubs
We restructured the website from a static portfolio into a tiered, localized entity system. By creating dedicated regional hubs—Marin County, Napa Valley, and Sonoma County—each with its own town-specific portfolio pages, we demonstrated clear geographic authority to both traditional search engines and AI platforms.
Copywriting for SEO & AEO
Modifying existing pages and creating new ones was vital to the project’s success. We focused on crafting copy that highlighted target keywords alongside Holder Parlette’s exceptional work and expertise.
Long-Tail & Intent-Driven Keyword Strategy
Instead of competing for broad search terms like “architectural firm” or “contemporary architecture,” we focused on low-volume, high-intent keywords. In Holder Parlette’s market, ranking for a handful of highly specific searches is far more valuable than competing for thousands of low-intent* visitors.
We targeted hyper-focused (long-tail) keywords that reflect real client concerns and problems. By including keywords for regulatory and local zoning realities, the portfolio pages develop a higher degree of local authority. For example:
- “Modern Napa Valley farmhouse architects”: Captures prospective estate owners looking for a specific aesthetic and regional design expertise in the Wine Country.
- “Sustainable Architecture for Marin County”: Reaches homeowners prioritizing environmental protection, personal well-being, and long-term financial efficiency
* Low-intent website visitors are usually students and people that are not looking for an Architect to hire—low commercial intent.
AEO (Answer Engine Optimization)
Generative Engine Optimization
To ensure AI tools like ChatGPT, Claude, Gemini, and Perplexity recommend Holder Parlette as a top authority, we shaped the site’s content to give clear, direct answers to the exact questions prospective clients ask. We laid out their expertise in a straightforward format that AI engines can easily read, understand, and cite.
AI Snippet & Direct Answer Integration
We incorporated structured answer blocks specifically tailored to trigger AI citations and Google Overviews, answering complex home design queries directly:
- “How do I build a fire-resistant home in California?” — Detailed breakdown of Chapter 7A compliance, Class A roofing, ASTM E2886 ember-resistant vents, multi-pane tempered glazing, and 5-foot Zone 0 non-combustible perimeters.
- “What are WUI requirements for Marin and Napa?” — Clear definitions of Title 24 Part 7 mandates, ignition-resistant building envelopes, and defensible space integration.
Writing for SEO & AEO
The “Location + Local Challenge + Solution” Narrative Formula
We restructured portfolio text from aesthetic descriptions into technical problem-solving case studies. Each project highlights local regulatory constraints and architectural solutions.
Examples
- Mill Valley Residence
- Local Challenge: Located at the base of Mount Tamalpais with a steep hillside slope and dense timber fire risk.
- Solution: Class 1 fire-rated backer boards behind wood siding, cement board paneling, and composite fireproof roofing.
- Sonoma Ridge House
- Local Challenge: Ridgetop exposure with severe wind-driven ember vulnerability.
- Solution: Designed an agrarian concrete and metal central spine to wrap the home in non-combustible materials.

Over the 14-month engagement, Holder Parlette’s business grew by over 200%. While this makes us incredibly happy, it’s important to anchor that number in reality: an architectural firm doesn’t increase revenue by this much through website optimization alone.
Holder Parlette’s reputation, word-of-mouth referrals, and deep relationships with local contractors and past clients also drove momentum. What our SEO and AEO work accomplished was opening a clear, highly targeted entry into Holder Parlette. By capturing homeowners at or near the moment they were searching for “Their Architect,” we ensured the firm’s digital presence was an extension of the quality of their work.
