Match types and negative keywords
Property campaigns burn through budget faster than almost any other category if match types and negatives are wrong.
Run almost everything as phrase or exact match. Use broad match modifiers only for testing, with strict negative keyword lists. Build a negative list from day one that excludes:
Geographic terms outside your service area. If you only operate in central London, exclude every London suburb and every UK city. The geographic reach of broad terms is significant and can drain budget invisibly.
Information-only terms. "How much is", "what is the average", "council tax band", "EPC rating", "what is stamp duty". These are research queries, not commercial queries. The clicks rarely convert.
Career terms. "Estate agent jobs", "estate agent salary", "letting agent qualifications". Recruiters and job seekers click these.
Comparison and review aggregators outside your firm. "Reviews of all London estate agents", "best estate agent in London". These tend to drive traffic to comparison sites or directories rather than direct enquiries.
Failed transaction terms. "Estate agent complaints", "letting agent dispute", "property scam". These attract negative-intent traffic.
Review search terms weekly. The reports show exactly what people typed before clicking your ad. Patterns will emerge. Add winners as exact match keywords. Add losers as negatives.
