Companies could see significant results from their marketing campaigns by combining search, email and social media, it has been suggested.
One way of doing this is by using search engine optimisation (SEO) to increase traffic to website pages for signing up to a mailing list or newsletter, according to Jordan Ayan of Email Insider.
Marketers could also publish their email newsletters on the web and optimise these pages to be visible to search engines, as well as use social media to promote website content - such as through social bookmarking and blogging, for example.
"If you blog, it should interact with your email marketing. For example, it should contain a subscription link to your newsletter," Mr Ayan said.
He added: "If people like what you blog about, they are likely to enjoy your newsletter."
A frequently updated blog can also do much to boost an SEO campaign, according to E-consultancy's Graham Charlton.
