Of course, there are downsides to using SEA for your business or website. Namely, the following:
It costs money. And it’s not cheap. With SEA, you pay for every click to your website. So you must also have a large marketing budget if you want to afford it.
When (temporarily) stopped, you lose. Relative to SEO, SEA is a short-term strategy. So when you stop paying for your ads for a while, you also immediately sink or disappear from the top search results. As a result, you immediately have less traffic to your website.
An SEA strategy takes a lot of time. Setting up SEA directly is possible, but not wise. Especially with SEA, it is valuable to know which audience you want to target and what search terms they use. Setting up such a thoughtful strategy takes time.
