I would seriously consider an optomizing service for your website.If you dont know what that is,its a service that examines your website,your traffic, your customers buying habits, and helps tailor your metatags to reflect your website.You may be getting lots of traffic to your website, but if its the wrong kind of traffic then it really isnt helping matters much.
Last year we dropped $300 on a service for our website, and after ten days they sent us an updated metatags list as well as other recomendations for our website.Within a week of implementing these changes, our hits more than doubled and our business saw a 60 percent increase in business.Needless to say it paid for itself in that first week.
