Fairly straightforward question. I am building a site for a cycle holiday company. Something they offer is 2 day breaks. I want to emphasise this for the purposes of SEO. Does anyone know if google equates '2' with 'two', '3' with 'three' etc? If numbers are an important part of the essence of what a page is about, then do I need to ensure I include both the numeral and word versions of numbers in my titles & META desc/keywords?
