GOOGLE AI
Query: "commercial roofing and waterproofing contractor Los Angeles recommendations"
Google's AI summaries favor businesses with strong entity signals: schema markup, consistent citations, and active content. Letner has been in business since 1957 and has roofed landmarks like Angel Stadium and Cedars Sinai, but none of this is structured in a way Google's AI can read. The blog has been "under construction" since 2016, giving AI zero fresh content to index.

Central Roofing started 35 years after you and gets recommended 3 out of 6 times by AI. You have nearly 70 years of history, landmark projects like Angel Stadium and Cedars Sinai, and more referring domains than Royal Roofing. But AI does not know any of this because the signals are not structured for it.
Technical Analysis
Website & Technical Gaps Holding You Back
Critical Issues Found
- !Blog "under construction" since 2016 - 10 years with zero blog content published. AI has nothing fresh to index from your site. Competitors publishing regular content are training AI to recommend them instead.
- !Only 9 organic keywords, ALL branded - you rank for "letner" and "letner roofing" but zero non-branded terms. Nobody searching "commercial roofing Los Angeles" will ever find you organically.
- !No schema markup detected - despite running WordPress, there is no structured data for AI to parse. No LocalBusiness, no Organization, no Service schema at all.
- !Iconic project portfolio is invisible to AI - Angel Stadium, Cedars Sinai, Honda Center, UCLA Royce Hall. Incredible work, but not structured as case studies, not marked up with schema, not written in a way AI can consume.
- !No visible reviews or testimonials - no Google reviews surfaced on site, no third-party review signals found. AI relies heavily on review data to build trust recommendations.

Why This Matters for AI
- ★AI systems weigh review signals heavily when deciding which businesses to recommend. Without visible reviews, AI has no social proof to justify recommending Letner.
- ★Central Roofing gets cited 3 out of 6 times with 67 reviews. Royal Roofing gets cited twice with 100 reviews. You have roofed Angel Stadium but have no review signal for AI to reference.
- ★Your 67 years of project history is an incredible trust signal. But trust signals only work when AI can find and read them. Right now, they are locked inside a website AI cannot parse.
You have nearly 70 years of landmark projects across Los Angeles. The only thing missing is making AI systems aware of what the LA skyline already proves.

Your blog has been "under construction" for 10 years. Meanwhile, competitors with active content are training AI to recommend them. With your 67-year legacy and landmark portfolio, the foundation is already stronger than any competitor. We estimate 3-5 months to first AI citations, with consistent growth from there.
Common Questions
Questions You Might Be Thinking
?
How is this different from regular website work?
Traditional website work focuses on Google search rankings. AI visibility targets ChatGPT, Perplexity, and Google AI Overviews, which are rapidly becoming how property managers and GCs find commercial roofing contractors. It requires structured data, entity building, and citation networks that go beyond standard web design.
?
How long until we see results?
Based on our track record, first AI citations typically appear within 2-4 months. Our dental client reached #1 in ChatGPT within 5 months. Your 67-year track record and landmark project portfolio give you a foundation most competitors cannot match once AI can actually read it.
?
Can you guarantee AI rankings?
No one can guarantee specific AI placements, and anyone who does is not being honest. What we can guarantee is implementing the proven framework that has achieved #1 AI rankings for every client we have worked with. The methodology is sound and repeatable.
?
We have been in business since 1957. Why do we need this now?
Your reputation is built on nearly 70 years of work. But when a property manager asks AI "who is the best commercial roofer in LA?" today, you are invisible while companies that started 35 years after you get every recommendation. Every commercial project that starts with an AI search is a project you are not even competing for right now.
