How many key-phrases should I have?

Again this will become apparent from the analysis we undertake, tools we use, and resulting discussions with you – but as a general guide bear in mind, “each web page can only be fully optimised for one key-phrase” (or family of key-phrases), so if you have 20 pages to your website then we’ll help you identify the 20 key-phrases most likely to bring highest visitor numbers (or best performing) to your website.

If you have 500 product pages spread between 35 categories in an e-commerce environment, then in theory this could support over 500 key-phrases, although these are likely to need to be considered in 35 families of key-phrases.
