Choosing digital marketing channels for my business

My organization is in the introductory phase with limited capital and we need to gauge consumer interest before proceeding further. Based on these organizational characteristics and goals, the following digital marketing channels are ranked in order of efficiency:

Social Media marketing
Social media will allow us to increase brand awareness, develop traffic and engagement with consumers, and receive responses to posed questions in a cost-effective manner. We can gather feedback regarding composition of the packages, pricing, interest and other pertinent areas. We will have a prominent social media presence across multiple platforms which each containing our website URL. Our objective will be to increase social media engagement across all platforms.

Display marketing
Display marketing will assist with reaching consumers based on likely websites they visit. A profile of our target market (demographics, behavioral, interests, etc.) can be used to effectively reach consumers. Remarketing techniques will be used after consumers visit our website.

Pay-per-click (PPC) marketing
As a small business with limited popularity and backlinks, it will be difficult to appear on the first page of SERP (search engine results page). Consequently, we will have to implement a paid search strategy to show on the first page based on keywords we wish to bid. We plan on actively using  Google Ads search advertising to generate ads on search engine results pages.

Search engine optimization (SEO) marketing
While building our brand awareness, customer following and engagement via social media, we will implement an effective SEO strategy for our website to increase organic search rankings based on keywords. 

Mobile marketing
Our mobile efforts will maximize the four channels listed above as most consumers will interact with our business via this format. Our website will be designed to be mobile friendly and the purchase process will be simple and easy to read.
