What we mean by affordable
We have seen two extremes in the SEO field.
There are companies that claim top 10 placement in search engine results for $50.
Than there are other speicialists that might charge $70-$200 per hour. Some of them might be well worth of it, some not.
What we mean by affordable SEO services is an hourly rate of $15. We charge by minute, not by an hour, thus if we will work only 45 minutes on a task, that particular task will cost you $9 only. Alternatively, we can work on a paid-by-project basis, where a fixed price is agreed. Also, some services can be agreed on a per-item basis, like directory listing submissions.
The main motto of affordable optimization services shall always be the return on investment for the client. It really is not that much abou who is cheaper, but about who will bring the return on investment.
