Short answer: at Byter, SEO costs £300 a month plus VAT for the basics (a technical audit, keyword research and on-page fixes) and £600 a month plus VAT for full SEO, which adds ongoing management, link building and monthly reporting. It is also included in our marketing packages from £750 a month. Packages run on a six-month term, then month to month.
