I have a testimonial video that I uploaded to my youtube channel. I also would like to post it to my site. Does it make any difference for seo if I upload video to my site or use an embed link from you tube?

I have a service business and we service many small suburb cities. I'm thinking about making a webpage for each city, optimize it very well for that city and redirect it to my front page. Would that work, or google crowlers will bring my score down?

provide carpet cleaning services in Cleveland Ohio would you give me your opinion if it is user friendly in. Thank you.
