How this was written. Awesome B2B wrote this article with a language model from MarTech’s reporting (model: @cf/meta/llama-3.3-70b-instruct-fp8-fast); it describes that reporting rather than adding to it. The original, linked above, is the full story.

Key points from MarTech’s report

  • B2B buyers complete nearly 70% of the buying process before engaging with sellers.
  • Cognitive-load testing measures mental effort expended to understand and act on a website.
  • Reducing cognitive load is key to establishing confidence and creating an evidence chain.
  • Clearer websites are easier for AI to interpret and summarize.
  • Buyers make more of the decision independently while spending less time evaluating each website.

B2B buyers arrive at websites with questions and limited time, and if they struggle to find information, they may lose trust and leave, according to MarTech.

Research from 6sense found that buyers complete nearly 70% of the buying process before engaging with sellers, making the website a crucial part of the buyer's preliminary due diligence.

The median average session duration for B2B companies is only 78 seconds, and buyers make more of the decision independently while spending less time evaluating each website, MarTech reported.

Cognitive-load testing measures how much mental effort buyers expend to understand, trust, and act on a website, covering areas such as comprehension, orientation, credibility, and action.

Reducing cognitive load doesn't mean simplifying a sophisticated offering, but rather organizing detail around the way buyers evaluate risk, with the goal of establishing confidence and creating an evidence chain.

Clearer websites are also easier for AI to interpret, with practices such as clear headings, consistent names for products, and direct definitions of proprietary terms making content easier for machines to understand and summarize.

The strongest websites create an evidence chain, with claim, metric, source, methodology, and product capability, and cognitive-load testing helps determine whether the website keeps buyers engaged.
