The part of the page you most want to rewrite is usually the part that is already working.
Copy refreshes on paid landing pages tend to go the same way. Someone reads the page with fresh eyes, decides it sounds like every other vendor in the category, and rewrites it from the top down. The hero headline goes first, because it is the most visible sentence on the page and the easiest thing to have an opinion about.
That is the one line I would leave alone.
Freeze the hero headline, rewrite everything under it
If your hero headline was live while the page was producing qualified leads from paid traffic, it is not a draft. It is a control, and it is the sentence doing the most specific job on the page: confirming within a second of the click that the ad this person just clicked was telling the truth. Google's own Quality Score documentation treats ad and landing page relevance as the same problem, and the headline is where that relevance either lands or breaks.
Rewriting it as part of a tone cleanup means you changed the variable most tightly tied to conversion rate at the same moment you changed six other things. When the page moves next month, up or down, you will not be able to say which edit did it.
So the working rule is simple. The headline changes only as a deliberate test with its own hypothesis and its own before-and-after read. Everything below it is fair game.
This is also why a copy refresh is not a redesign. If the page converts, the thing you are fixing is credibility, not the offer.

On a typical B2B or high-consideration services page, the copy that needs work is a short and predictable list.
→ The introduction. Usually written last, usually the vaguest block on the page, and usually the first thing a skeptical buyer reads after the headline.
→ The founding team or credibility block. This is where self-praise piles up fastest, because nobody knows how to describe their own team without sounding like a brochure.
→ The process section. Almost always too long, and almost always describing the same phase two or three times in different words.
→ The paragraph immediately above the form. It carries more weight than its length suggests and it is the block most often left as filler.
Fixing those four is a real project. It is also a much smaller project than rewriting the page, and it does not put your conversion rate at risk while you do it.
Your best copy source is a recording of your own sales calls
The most reliable source of body copy for a considered B2B purchase is a recording of a real sales call, because the language a founder or salesperson already uses to explain the work to a stranger has been pressure-tested by people who can say no. Marketing copy written from the pitch deck has not been.
Pull three or four recent calls. Find the moment the buyer asks some version of "so how does this actually work," and write down the answer close to verbatim, including the plain words. If your salesperson says "we scope it, you sign off on the number, then we build it," that sentence is better page copy than any polished version of it.
I have seen this produce better results than any structured copywriting exercise, and it costs an afternoon. The reason it works is unglamorous. A sales call is the only place where your positioning has already survived contact with a buyer.
Two cautions. Do not paste customer names or specifics from a call onto a public page without permission. And listen for the questions your buyer asks that your page never answers, which is often more valuable than the phrasing.
Three things to cut on sight
1.) Self-praise the buyer has no reason to believe. "Industry-leading," "award-winning," "trusted by the best." These cost you a sentence and buy nothing, because a claim about yourself is the least credible kind of claim on a page. Replace it with something checkable: a number of projects, a named platform you are certified on, a specific constraint you work within.
2.) Premium adjectives that describe nothing. Bespoke, curated, elevated, seamless, thoughtful. Strip every one of them out and read the sentence again. If the meaning did not change, the word was decoration. Buyers of expensive things are not persuaded by expensive-sounding words, they are persuaded by evidence that you know what you are doing.
3.) Process copy that restates itself. A process section will often name a phase, describe it, then describe it again from a slightly different angle. Say it once, in sequence, with what the client actually does at each step. For a services buyer, naming each phase in order with the budget check-in that sits at the end of it is more reassuring than a paragraph of adjectives about collaboration, because it tells them exactly when they will be asked to make a decision and what they will be deciding.
None of this makes the page sound cheaper. Plain, sequential, checkable description reads as more competent, not less. In my experience the bigger the company gets, the weaker its headlines and positioning get, and it is almost always because someone added words instead of removing them.
A wall of reviews is not social proof
Third-party review proof does lift conversion for considered B2B purchases. A hidden library of it does not.
Nielsen Norman Group's analysis of instrumented browsing behavior put the ceiling at about 28% of the words on a page, with 20% the likelier figure. That study is from 2008 and covered 25 users, so treat it as directional rather than precise. The direction has not reversed. People scan.
Which means a testimonial section holding twenty reviews inside a carousel that shows four is carrying sixteen reviews of dead weight. It looks like proof to the team that built it and reads as a widget to everyone else.
Cut it down to a handful that stay visible without interaction, and choose them for relevance rather than enthusiasm. One review from a company that looks like the buyer, naming the specific problem you solved, does more than a dozen general compliments. If you have real ratings on a review platform your category respects, show the rating and link out to the full set instead of embedding all of it.
If you sell in a regulated category, get the titles checked before you launch
Licensed and regulated professions restrict which job titles and credentials can appear in marketing. The distinction between a protected title and a permitted description of the same work is a legal line, not a stylistic one, and a copywriter working from your website will not know where it sits.
Have a subject-matter reviewer inside the business sign off on title, credential, and technical language before the page goes live, and do it before the copy is final rather than after. This is cheap insurance, and on paid traffic it also protects you at the ad level, where the same restricted words tend to end up in headlines.
Sequencing a rewrite on a page that is running paid traffic
1.) Pull the page's conversion rate and lead quality for the last 60 to 90 days so you have a real baseline, not a feeling.
2.) Lock the headline and subhead. Write them down somewhere as the control.
3.) Rewrite the four body blocks: introduction, credibility, process, and the paragraph above the form. Source the language from sales calls.
4.) Trim the proof section to what stays visible.
5.) Get the compliance read.
6.) Ship the body rewrite as one change and give it enough traffic to judge. On a page taking a few hundred clicks a month, that is weeks, not days.
7.) Only then test the headline, on its own, against the control you wrote down in step two.
If step one is impossible because you cannot see conversion rate by page, fix that before you touch the copy. Rewriting a page you cannot measure is a preference, not an experiment. We cover the underlying discipline in message match for B2B paid search, and why the landing page is usually the biggest lever in paid search in the first place.
Where this leaves you
The instinct behind a copy rewrite is almost always right. Most B2B landing page copy is written by people describing their company to themselves, and it reads that way. The instinct about where to start is almost always wrong, because the headline is the loudest thing on the page and the last thing you should touch.
If you do one thing from this, open the three most recent recorded sales calls, find the moment the buyer asks how the work actually happens, and paste that answer into the process section of your page. Then leave the headline alone until you can test it properly.
