Probably, but without much more detail it seems like an average rate that could go in either direction. I generally treat retained services as more legitimate than flat rate plans. As I rarely do the same things twice, sure there are similar steps taken, but nothing is exactly the same.

Also offerings like, “4 blog articles a month, 1 site audit, 2 backlink audits, and a partridge in a pear tree.” are totally useless in SEO. You do what it takes to rank and every month you should have something different to do, sometimes that includes a disavow file, a backlink audit, or writing new blog articles, some months it is all about planning and strategy, and others are just on site code and UX revamps. It really depends on where you are and what is needed.
