Should I register my website?


I want to protect my website with the help of a trademark. I am looking to market my name, name with spaces and domain name.

Looking at the different classes, I would look at 16,35,36 and 41. I would not need 25 for the moment. This is on the GOV website for the UK.

Does any one have a trademark experience? If so, what trademarks should be used for a commercial / marketing content website?

i thought
35 – Advertising, business management and retail services
36 – Real estate and financial services
41 – Educational, entertainment, sports and cultural activities

Help would be appreciated!
