One of my clients recently called me up and asked that he wants his website to show up once people search for a particular keyword. And I oblige to do it for him, then he asked how much is it?

That was like an Amanpor question to G . . After beating around d bush, I told him N20k permonth. But as usual, he gave me 5k to start. When i completed it in like a week, he gave me 6k as against 15k. As at that time he was already on page 2 page 3.

Just this morning, I searched for his company keyword and find he is no 1on page 2. I also googled SEO price and I was surprised at what I saw. I called him immediately that his company is doing well and that I undercharged him and I wld appreciate if my 9k bal wld b available today and he said I shld come around later today.

If it were u, how much wld u charge per month or per annum for SEO service?

Firstly, you should NEVER discuss overcharging or undercharging with a customer. That is between, you and yourself. If the latter, you live and learn for another day.

There was a client I was doing SEO for about 2 years ago. I would write 1 article a month and submit to at least 10 article submission sites. I think I charged him $100 per month, so I don't think your 20K, if you can pry it from the client, is farfetched.

Good luck!
