There are loads of company's offering SEO for a low monthly fee. On the face of it these deals seem too good to ignore. I was looking at some SERPs recently and I saw a PPC advert which read, SEO for £199 plus VAT. I wondered what that meant.
If the company offering this service is a real company they will have overheads. Even with low overheads their day rate will be in the hundreds, assuming they understand day rates. Even being generous their overheads must be around £25 per hour, adding 20% profit brings this to £30/hour. So for £199 you would get just over six and a half hours.
This is fine, if all you want is some keyword research, or some general tidying up then six or seven hours is fine. If however you need strategic advice, competitor analysis, keyword research, link building, social media marketing, in short a professional SEO approach, it's not going to cut it.
I've looked long and hard at making our SEO services as affordable as possible, falling short of outsourcing it to the Indian sub continent, and I can't see how these guys can add any real value based on these budgets.
I look forward to being proved wrong ;)
