A roofing advertising campaign can attract plenty of attention while creating extra work for the office. Someone wants a job, someone wants to buy roof tiles, and someone wants advice about a product you do not install. Each conversation helps explain the difference between a search that sounds relevant and an enquiry your business can actually serve. Negative keywords are one way to act on that difference, but they deserve careful judgement. An exclusion that removes obvious waste can help; an exclusion that blocks useful language can quietly remove good opportunities too. Start with evidence from real conversations rather than a long borrowed list.
Record why an enquiry was unsuitable
Ask the person answering the telephone to capture a short reason when an enquiry is unsuitable. Useful reasons might include employment request, material purchase, unsupported roof system, outside operating area, or a genuine service enquiry that cannot be scheduled. These reasons are different. Someone asking for work is usually seeking something your service advertising does not offer. Someone calling about a repair when your diary is full may still be an appropriate customer. Treating both as unwanted traffic hides a capacity problem inside an advertising decision. Keep notes factual, brief and consistent so the review identifies patterns without becoming another administrative burden.
The office should also distinguish an unsuitable enquiry from an unsuccessful sale. A homeowner who declines a quote has not necessarily used the wrong search. They may prefer another contractor, need a different appointment, or lack funds for the proposed work. If every lost quote becomes a reason for exclusion, the campaign can become progressively narrower without becoming better. Record the reason you know and leave uncertainty visible. A simple category such as unclear is more useful than an invented explanation. Review several examples together before assuming that one disappointing conversation represents a recurring problem.
Connect conversations with search language
Where your reporting allows it, compare unsuitable enquiries with the search terms associated with campaign activity. Google explains that the search terms report shows searches that triggered impressions and clicks, subject to reporting limitations. It is therefore a source of evidence, not a complete transcript of every search. Look for language that consistently suggests a different purpose. A hypothetical query about roofing apprenticeships points towards employment, while a query about buying individual slates suggests supplies. Write down the phrase, the reason it appears unsuitable, and the evidence supporting that interpretation before making a change.
Avoid pretending that every telephone conversation can be matched to a single search. Attribution may be incomplete, several people may share a device, or a customer may return later through another route. Use available tracking carefully and combine it with recurring patterns. If the office receives repeated supplier enquiries while visible search terms include product shopping language, that is a stronger basis for investigation than one unrelated call. A short review note can say that the connection is probable rather than certain. Honest uncertainty supports better decisions because it encourages monitoring after a change instead of declaring the issue permanently solved.
Exclude the intention with care
Negative keywords have their own matching behaviour, and their operation differs from positive keywords. Before applying an exclusion, check Google's guidance on negative keywords and understand which searches the chosen match type can prevent. Do not assume that adding one phrase automatically covers every related spelling, singular or plural form. Equally, do not broaden an exclusion just because a shorter word looks easier to maintain. The aim is to remove an irrelevant intention with the smallest sensible change. A phrase that clearly describes employment can be safer than excluding a broad word that also appears in useful roofing enquiries.
Consider a hypothetical business that repairs slate roofs but does not sell roofing materials. Excluding a carefully chosen supply related phrase may make sense when evidence shows repeated shopping enquiries. Excluding slate itself would conflict with a service the business wants to promote. Similar care applies to cheap, advice, cost and small. A customer using cost may be ready to request a quotation. Someone asking about a small repair may own a property that needs more substantial work after inspection. Interpret language in the context of the business offer rather than making assumptions about a person's value from one word.
Choose where the exclusion belongs
An exclusion can be appropriate for one part of a campaign structure and inappropriate elsewhere. A contractor may advertise pitched roofing and flat roofing separately, with different offers and teams. A term that should not reach one service may be welcome in another. Before applying a shared exclusion, check every campaign it will affect and document why it belongs there. Keep broad business exclusions separate from service specific decisions. That makes later reviews easier and helps prevent a future service launch inheriting restrictions that were sensible when the business had a narrower offer.
Review inherited lists with the same care as new additions. A former agency, previous employee or earlier business model may have left exclusions that nobody can explain. Do not delete everything at once. Group the terms by purpose, identify obvious conflicts, and investigate uncertain entries. A short description beside each important decision saves time later: materials only, employment only, or service not offered. If the company starts installing a roof system it previously declined, the advertising restrictions should be reviewed alongside the website and office script. Operational changes should trigger advertising checks rather than waiting for a performance problem.
Make changes you can evaluate
Keep a simple change log containing the exclusion, its scope, the reason and the person responsible for review. You do not need a complicated reporting system. You need enough information to understand what changed when enquiry patterns move. Avoid making a large collection of unrelated changes together if you want to learn which decision helped. After an exclusion, watch the volume and quality of suitable enquiries alongside the unwanted category. A reduction in irrelevant calls is useful only if the business can still attract the customers it wants. Context matters more than a tidy looking list.
Set a practical review rhythm with the office and marketing team. Discuss repeated unsuitable enquiries, surprising suitable ones, and changes in the services you can deliver. Keep a route for challenging an exclusion when customer language differs from internal terminology. Roofing customers often describe symptoms rather than systems, so their wording can be imperfect while their need is real. Negative keywords work best as a maintained record of business boundaries, informed by actual enquiries and checked against platform guidance. Galaxy Roofer Marketing can help connect that feedback with campaign decisions so your advertising remains aligned with the work you want to quote.
