How time flies. I joined this forums for 7 years. I didn't post much on this forums. Currently I have 2 companies, one is for online stores for optics, and the other is for amazon. I can offer: 1. All the useful information about Amazon. 2. Some useful skills for Google SEO. 3. How to run Tik Tok. I need : 1 Ads spaces on blogs or websites. We're selling optics products, science and tech websites are good for us. 2 Any new marketing methods for the year 2021. Thanks
