Despite the rise of internet promotion and guerrilla marketing, adverts (both hard-copy and online) still have a place at the sales and marketing table.  They are typically useless in isolation, though – don’t place a single advert in your local paper and expect to receive floods of enquiries as a result.  They have a value when repeated regularly (it takes 7 impressions for a prospect to fully take in who you are and what you do), and when used in combination with PR or mailshots.  For an online offensive, consider pay-per-click and remarketing advertising – as part of a holistic marketing approach, these activities can really bring results.
