Most custom GPTs do not fail because the idea is bad.
They fail because the knowledge behind them is too messy for the GPT to use well.
A lot of B2B technology teams are experimenting with GPTs for sales enablement, content creation, internal workflows, and marketing operations.
But then the outputs come back inconsistent.
The GPT misses context.
It gives generic answers.
It overlooks important details.
The issue is often not the model.
It is the structure of the source knowledge.
GPTs do not retrieve knowledge as full documents. They retrieve it in chunks.
That means a large wall of text is harder for the GPT to search, interpret, and apply correctly.
Structured knowledge documents work better because they give the GPT clearer paths to the right information.
Markdown headings.
JSON fields.
XML structure.
Clear sections.
Field-specific instructions.
Think of structure like an index.
It helps the GPT find the right information faster and produce a better answer.
If you want better GPT outputs, do not just upload more information.
Structure the information better.
The same principle applies to marketing systems.
Unstructured inputs create inconsistent outputs. Structured systems make ex*****on easier to guide, improve, and scale.
That is one of the ideas behind the PRESTO marketing system.
It gives B2B technology companies a clearer structure for turning buyer pain, positioning, search intent, and conversion strategy into marketing that supports pipeline.
