Need some help with internet marketing

Hi! My partner and I have launched our new shop and our website is done. As for the moment, we are promoting by social media accounts like Facebook, Twitter and Instagram. We heard about boosting a site's page rank so more potential customers can easily find our business page. We found out about SEO, SMM and B2B Marketing. Do you guys know anything about it? We really need some help on internet marketing especially the latter ( B2B marketing). Any suggestion would be really great. Thanks so much for your time!

SEO is basically search engine optimization which includes various factors such as keyword placement in your webpage content, mobile friendliness of your content, your involvement in social media, link building, reputation management as well as paid marketing campaign. You should talk to a SEO services company, I think they will be able to explain your better.
