One of the most common mistakes is paying for ads before understanding how they work. Running Google or Facebook ads without knowing how to target the right audience or read the results properly can drain money fast. Another mistake is buying expensive tools or courses before even testing whether a basic free approach works first. Some people also pay for services they do not fully understand, like outsourcing SEO without knowing enough to check if the work is being done right. Spending money on things that look professional but bring no real results is something a lot of beginners go through. What do you think is the most avoidable money mistake in early digital marketing?
