Why we're making our product pages shorter, not longer

The conventional wisdom in conversion rate optimisation says long-form landing pages convert better. More social proof, more objection handling, more detail, more trust signals. For years we applied this to our own service pages and recommended it to clients. It felt right. It was also, in our case, probably wrong.
The moment I started questioning this was a client project for a legal services firm in Bangalore. They had a beautifully detailed practice area page. Eight hundred words explaining every service, three testimonials, a detailed FAQ, logos of clients they had worked with, and a contact form buried at the bottom. Traffic was decent. Conversions were not.
We stripped the page. Cut it from 800 words to 220. Kept one testimonial, the contact form moved to the top right, and a single clear sentence at the top describing who the page was for. Conversions went up 34 percent.
What I think was actually happening
The long version of the page was written for someone with unlimited time and maximum uncertainty. It tried to answer every question before the visitor asked it. The problem is that most visitors who are ready to contact a legal firm already know they need a lawyer. They are not reading eight paragraphs to become convinced. They are looking for a phone number and a reason to trust the person on the other end.
The information that builds trust for a ready-to-act visitor is different from the information that builds trust for someone who is still researching. We were conflating the two audiences and writing for the more uncertain one.
For clients who are still in research mode, a long detailed page makes sense. But those visitors rarely convert on first visit anyway. They bookmark, leave, and come back. Or they never come back. Optimising your primary conversion page for researchers at the expense of your actual decision-stage visitors is a mistake.
What we are doing on our own pages
We are running the same logic through our own service pages now. The web development service page was 1,100 words. We have cut it to around 380. The SEO page is next.
The parts we kept: a specific description of who this is for, one strong client result with numbers, the actual starting price, and a contact form that takes thirty seconds to fill in.
The parts we removed: the exhaustive process explanation, the FAQ section, the "why choose us" block that every agency has and nobody reads, and the team section that was already on the About page.
Every element on a page either helps a ready buyer take action or it does not. If it does not, it is noise. Noise increases cognitive load. Cognitive load kills conversions.
This does not mean short always wins. There are product categories where uncertainty is high and research is part of the buying process, and there long-form content earns its place. But for professional services where the visitor has already decided they need the type of thing you offer, getting out of their way is the better design choice.
