Hi Fammy,
Just concentrate on content quality and internal links.
1. If your content is genuine, fresh and informative, no one can stop it from being ranked.
2. Internal linking of your website is second most important task to be done simultaneously. While linking your website internally, don't forget to assign keyword to every page and then whenever these keywords repeat in your content, just get them linked to relevant page of your website.
3. Third and equally important task is post content on regular basis. The more you write about your services or product, the more you get from search engine. So the third key of quick ranking is "Regular post".
4. Don't stop using social media. It might be the great way for you to reach out your audience. Without getting rank you may get good traffic as well as leads.
5. Don't waste your time in creating spam links and don't buy links. Forget it for a while until you create your website completely with great content.
Thanks
