I find this interesting because in SEO we look for keywords that are going to boost organic search results. An issue has come up where my client has been asked to not use two descriptive words which I've been using in my SEO for them. I use various keyword tools to get the best results. These words have increased their organic search results greatly; the SEO is working otherwise we wouldn't get a complaint, I expect. We rank second to the complainant. I have not used those key phrases maliciously or intentionally to harm, however, these words (plus others) perfectly describe what my client offers. Two of those words are in the other company's business name and domain name. Also I didn't use the words exactly as the business name reads - there were other words inbetween, or they were swapped around, specifically so that it wouldn't appear exactly the same. This is related to the travel industry and those words are used frequently within leisure travel. The key phrases are used in their descriptions on their Facebook page and other Social Media, throughout their website content and meta tags, in our adwords campaigns and collateral materials. I don't want to make those words public here if possible, but would appreciate your thoughts and any questions as to 1) what rights my client has to be able to use any words he likes in SEO campaigns, and 2) as the SEO consultant, if this gets nasty, who would be in the firing line if the other company wishes to take further action, say for copyright infringement? Thank you!
