Search engine optimisation strategies can be divided into two principal camps: pay per click SEO and natural SEO. Whilst pay per click SEO captures visitors for a fee through paid placements, natural SEO taps into 'free' search engine traffic using technical web design and development techniques.
Natural SEO can make dramatic improvements to the quality and volume of visitors to your website, but this can be more challenging to achieve, not to mention maintain, than through pay per click SEO. Natural SEO placements are highly sought after, which makes positioning extremely competitive.
