How to build a predictable B2B lead generation engine

Most lead gen isn’t an engine. It’s a slot machine you keep feeding. Here’s the version you can actually forecast. Predictable is the word that matters here. Not “more leads.” Not “better leads.” Predictable. A predictable engine means you can look at what goes in this month and forecast what comes out next quarter, inside […]

The Complete Guide to AI Search Optimization (AEO, GEO & LLMO)

AI search optimization is the work of getting your brand quoted, cited, and recommended inside the answers that ChatGPT, Perplexity, Gemini, Copilot, Claude, and Google’s AI Overviews give. People searching for it use three overlapping labels: answer engine optimization (AEO), generative engine optimization (GEO), and LLM optimization (LLMO).

LLMO & GEO Strategies That Increase Brand Visibility in AI Search

A global enterprise brand has spent years building category authority. Its website ranks. Its content is indexed. Its PR team produces regular coverage in respected publications. And yet, when a procurement lead at a Fortune 500 asks ChatGPT to summarise the top vendors in that category, the brand is absent, mischaracterised, or placed in the […]

The Complete Guide to Answer Engine Optimization (AEO)

Content that ranks on page 1 of Google but gets ignored by Google’s AI Overview is content that’s losing ground. A growing share of your audience receives an answer without clicking anywhere. For content marketers, AEO is the discipline that decides whether your content is the source of that answer or invisible to it. Answer […]

How to Get Your Brand Mentioned by ChatGPT, Gemini, Claude & Perplexity

When a SaaS buyer asks ChatGPT to recommend a project management tool for a 200-person engineering team, your brand either appears in that answer or a competitor’s does.

Why most B2B websites fail to convert visitors into leads

SHORT ANSWERMost B2B websites fail to convert because they are built like brochures, not conversion tools. The value proposition is vague, the copy is full of jargon, the call to action is weak, and the contact form asks for nothing useful. Fix those four and lead volume climbs without a single extra visitor. Your B2B […]

How Google AI Overviews are going to affect your SEO traffic

Google AI Overviews answer many queries directly on the results page, so fewer people click through to websites. Pew Research Center (July 2025) found users clicked a link on 8% of searches that showed an AI Overview, against 15% without one. Informational and top-of-funnel pages lose the most traffic; high-intent and cited pages hold up. […]

Why Topic Clusters Outperform Traditional SEO in Competitive B2B Industries

Targeting one keyword at a time in a competitive B2B market is a strategy that produces diminishing returns. The companies dominating their categories are winning entire topic areas. Topic clusters are how that happens. Traditional keyword-by-keyword SEO made sense when search was simpler. Pick a term, write a page, build links to it, rank. In […]
