Across sixteen searches on 18 September 2026, one result quoted a range. That says more about the market than the range does.
The short answer
There is no standard price. Published ranges run from a few thousand dollars a month to six figures a year. Most work is sold as a retainer, and the biggest cost driver is whether anyone does execution or only reports.
What ranked on 18 September 2026: One listicle quoted five thousand to one hundred and fifty thousand dollars. That is a category description, not a price. Every other result offered a contact form.
