What do you think, how many people per day do google for problem solutions, a specific product or a service in your region, in your sector?
...and how many land with a request in your inbox? or with the competition?
... well, in search market Google has a market share of about 50%. Have you expected a higher number? Google is not the only search machine. Big competitors are for example travel portals like booking, ebookers, or hotel portals like trivago, and last but not least Amazon for goods and books. Not to forget many local players for electronics, cars, etc.
...what are the implications for you as SME owner, a self-employed professional in craft, trade, service? As thousands of search request per day are transacted via goolge, you need to be present in an optimal way there. And it is not only your website, but much more.
