Many commentators are saying that traditional seo is dying, with the array of new advertising methods and platforms available. Mobile phones, tablet pc’s, Google pushing local search to the front pages etc.
However, you must remember that whatever device your potential customer is using to search, the results will still be search engine based. Local results being emphasised just means you need to add local search into the seo mix.
In 2011, SEO campaigns will still be of great importance in your marketing strategy. In 2010 many aspects of SEO that were most important will just be relegated and taken over by new seo methods. Such as local search, social networking and optimising your website for the mobile market.
As for search engines, Google will remain the daddy, but Bing will continue to grab market share (40% up already since launch), Yahoo is losing share so is not considered as important as the big two.
