Google Ads

What is with these google ads? I thought they were suppose to have something relevant to my blog. I won't mention what they are advertising because I don't want encourage those ads, but I would think the frequent reference to MOUNTAIN BIKING, CYCLING, and OUTDOOR RECREATION would get ads that had something to do with mountain biking, cycling and outdoor recreation, not ads based on the fact that someone else has the same name I have. I guess I may need to add some filters so I can get more mountain biking cycling and outdoor type things.
