No webshop can guarantee SEO results.
NEVER trust a company that promises top search rankings or claims to have special “insider deals” with the major search engines. Search Engines care about giving their users the absolute best search results for the keyword they are searching for. That way users keep coming back (and click on search engine ads). Anyone who claims to be able to guarantee rankings is not being honest with you.
Our philosophy is to take the most current white hat SEO techniques and apply them to your web site and let Google determine where you stack up. From there, we analyze and suggest ways to continually raise rankings based on actual data. An ongoing effort is what wins the race with SEO.
