Keep the brief to something you would be willing to send to three suppliers unchanged. The temptation is to tailor each one, which feels attentive and makes the resulting proposals impossible to compare. Identical briefs produce differences that reflect the agencies rather than the instructions, which is the entire point of asking more than one.
The gap is usually stark. Their page states a turnaround time, a coverage area, a price range and a limitation. Yours describes a commitment to quality and a passion for service. Only one of those contains anything to attach a citation to. generative engine optimization
What Not to Do, and Why It Backfires Fabricated reviews, seeded forum threads under false identities, and paid placements presented as independent all exist and all fail on the same axis. Detection has improved, platforms enforce against it, and the reputational cost when it surfaces exceeds anything the visibility was worth.
These names go directly into the prompt set and into any comparison content, and getting them wrong sends the entire measurement effort in the wrong direction. If you lose to a low cost regional operator rather than to the market leader, say so.
This is also why review volume and recency show up so consistently in what gets cited. A platform with forty recent accounts of working with you is more informative than your own page saying customers love you, and it is treated accordingly.
Then re-run the same ten prompts a month later and compare. Attributing improvement to a specific fix is only possible because you recorded the starting point, which is the argument for doing the teardown before the work rather than after it.
Ask who specifically will do the work, and ask to meet them. Capability in this field is thinly distributed and frequently sits with one or two people inside an agency of any size. A pitch delivered by a strategist who then hands the account to a junior is common enough to be worth checking for directly, and the question is easy to ask without giving offence.
Prioritise by your own citation data rather than by prestige. A trade directory nobody has heard of that appears in half your category's answers is worth more attention than a well known publication that never gets cited. generative engine optimization
Finally, pay attention to how they talk about their existing clients. Somebody who describes a client's category accurately, names the specific constraint that made the work difficult, and mentions something that did not work has actually done the job. Somebody who describes every engagement as a success in identical language has either been unusually lucky or is describing a template.
There is a variant of this worth checking separately. Sometimes you appear and the competitor appears above you, which is a different problem from being absent. In that case compare the specificity of the two descriptions rather than the sources: the company described in concrete terms tends to be listed first, because a specific description is easier to justify than a general one.
What Brands Usually Get Wrong in Response The instinctive response is to publish more brand content, which addresses none of the above. The second instinct is to try to displace the review site, which is not achievable and would not help if it were.
Good versions read like this: mention rate on evaluation prompts rose from two in fifteen to six in fifteen, which we attribute to the three directory corrections completed in week two, though a competitor also stopped publishing during the same period.
Give journalists and analysts accurate material to work from, in a form they can use without rewriting. Where an independent comparison exists and gets your details wrong, a polite factual correction is accepted far more often than people expect, because publishers generally do not want to be wrong.
There is also a mechanical problem. Manufactured mentions tend to be uniform in language and timing, which is exactly the pattern that gets discounted. The effort produces a body of sources that agree suspiciously well and carry less weight than a smaller number of genuine ones.
Run a commercial prompt in almost any category and look at what gets cited. Review platforms, roundups and comparison sites appear first and most often, and the brands being discussed appear well down the list if at all.
Look at What They Do About Third Party Sources This is where the real work lives and where weak proposals are thinnest. Ask specifically what they will do about the review platforms, directories, forums and comparison articles that assistants actually cite in your category.
Results Split by Intent, With Run Counts Not one number. Mention rate reported as a fraction with the run count visible, broken out by prompt tier, so buying intent is never blended with definitional questions.
One section most briefs omit is worth adding: what has already been tried and what happened. Agencies frequently propose work that was done two years ago and abandoned, because nobody told them. Listing previous efforts, including the ones that failed, saves a month and signals that you will be a straightforward client to work with.
