The fact is that 75% of people never scroll past the first page of the search engines. So if you are not found on that very first page for the search term(s) your customers are searching for you most likely won’t be seen. A website that is not going to be seen might as well be on Mars.
You may have paid a lot of money for design, but without search engine optimization your company will not be found on search engines. Ultimately, you want to be found first on Google, then look good.
