There are no fixed prices in the SEO world – and if you get a package offer, I recommend you stay away from those. My SEO pricing is always client-focused, understanding exactly what the client needs and then offer a clear pricing model.
Why is this question important? You do not want to work above your budget, neither will you want to hire an SEO consultant you can’t afford. Do not hire a consultant if you need a quick fix, but it is a bit efficient in saving cost when you need a website audit. You have to work within your budget limit, and that includes your SEO services.
