There is only one alternative to Google (if at all), that is Bing. I have used it extensively but very frustrated about Bing just refusing to crawl our sites at a much faster rate.
At times I feel websites are human – they catch some sort of infection (flu) which needs to be attended to immediately, else your reputation (revenues) takes a beating.
Most of us would agree a ‘brand’ has an influence on the liking of a product. Ask anyone ‘Which search engine works for you the best?”, the obvious answer you expect to hear is ‘Google of course’.
