Grow organically: Instagram, Pinterest and social media marketing, monthly committment

This is a monthly committment I am considering changing the freelancer that is doing the job currently >>General A makeup ecommerce site that slowly will start making way to the market. Awaiting the mobile app to be done. The images and posting is good, but there is no increasing number of followers. This is in makeup industry and is cosmetics with AI matching. so it is marketing the mobile app which has AI and skin tone matching. the very first in the world to do this. so it is the mobile app and selling our products in a mix. It is not only the app which they thought it should be. >>Work to do: 1. Create images and make suitable text and follow others and interact on the social media platforms 2. post images for makeup on instagram and pinterest every week. Currently 2 pw, should increase when the app is ready. 3. building interactions 4. increase generic growth 5. proper review of statistics and taking actions based on insights But it must be big and influential followers to start with. >>Content you must create: - Text for tweets for makeup/cosmetics - Images of makeup - Images of people using the app - Videos of the products that I provide, simpler gif animations would be your job The above list is not exhaustive and you as an EXPERIENCED marketing person should know what to do here. >>Target markets first UK later Europe later USA later India Examples of work to do in the above list of work ASO •for app download BASIC SEO: •Keyword Research, for website and mobile app •Website Analysis, (Google tags installed in both website and mobile app) •Google Search Console Set up (already setup) •Google Analytics Set up (already setup) ON-PAGE SEO: •Optimization of Title Tags •Optimization of Meta Description Tags •Optimization of Meta Keywords Tags •Analysis of non-index able attributes •Robots Optimization •Header Tags Optimization for all important pages •URL Optimization •Optimization of italics and bold tags •Optimization of external Links •Analysis of Broken Links •Checking of Canonicalization error •Website URL Redirection •Optimizing HTML Code •Image Analysis and Optimization of Alt and Title tags •Hyperlink Analysis and Optimization •Optimization of internal Navigation /linking structure •Cross browser compatibility •Checking the page size •Fix Canonicalization error •XML Site Map Creation >>MUST HAVE YOUR EXPERIENCE: - You must have experience with fashion and makeup to do this job.

So all analytics is added there to be successful. We cannot have dumbo behaviour with just positing images. >>SEO Also there must be SEO added and driven. I had one SEO social media precense person 8 months ago who did all SEO posting and tweets and was tracking and was following. I cannot get hold of him since we were doing some development on the app we are launching. >>Postings Not interacting with followers, not building a a precense and simply noth bothering about the statsitics which is key to be successful is like committing suicide slowly. I need someone who is very good at this and can interact and drive presence. Eventually I wantto have some small advertising. First out is posting tweets and make the feed live. Please share your experience and your knowledge in this area. References is what I am looking for to see if I should change. What would your cost be to do this per month?
