Running search engine marketing on a small budget is possible if you plan it carefully. One good approach is to focus on very specific keywords that match exactly what your product does, rather than broad terms that attract everyone. You can also set a daily budget cap so spending stays in control and does not run out too fast. Scheduling ads to run only during hours when your audience is most active also helps stretch the budget further. Prioritizing your best performing ads over weak ones saves money.
