I love it! I just came across a blog just on that topic! I love the effort and love the topic. Congratulations on launching a new baby - if done right you should be committing a lot of time in the near future. Possibly some financial resources as well.
I really like Rebecca's and Andra's responses:

My name is Humberto, I'm an inbound digital marketer and have helped countless entrepreneurs, coaches, startups, and fortune 500 companies - heck, even other marketers! I run www.unthink.me - a digital marketing agency that brings big-business marketing and tools to small growing companies.

I recently wrote answer for a coach, I suggest you read that because you fall under the same hurdle and potential model as well, https://clarity.fm/questions/4917/if-you-a-5-credit-on-fiverr-which-type-of-expert-would-you-choose-to-get .

What you need to figure out is your niche, you target millenials who are interested in their future. Under what specific situations? Female? Recent college grads? those want kids, no kids.. create a person as detailed as what type of beer they drink and if they were in your city, what bar would they most likely go to... etc - this gives you insight into what to write, how to write your content/insights/anecdotes, examples, etc. and where and how to promote to reach them.
On social media, what hashtags you would use are also determined by your niche persona, their interests, etc.
down to the image you use.

On your website:
Invest your time on SEO best practices, don't have more than 3 keyword variations on any given blog post, and don't repeat them each more than 5 times per post.

How are you hosting? if hosting on Wordpress for example there are a lot of good plugins that let you check traffic and SEO progress.

I also agree with them, is important to have modal popups on specific pages that promote certain value propositions, be very specific on this offers as most people won't jump into the 'Subscribe to our blog' offer! Don't be afraid to target with things like "this blog is specifically for _____, not so much for ____"
Don't be afraid of joining FB groups, sharing on twitter, Google+,etc and trying different title descriptions on each share. According to Hubspot, is ok and common to share the same post multiple times each with different titles and value props.

I just shared a note on Facebook, with more ways to increase traffic - it's all a numbers game - you approach, timing, etc, dictates the number of visitors you need for each 1 subscriber. That ratio will dictate whether or not you can rely on organic or if you'd have to pay for traffic through Google Ads.

At the end of the day, there is no secret formula, it just takes consistency, patience, and focus. - keep at it.

If this was helpful, all I ask is that next time you know of someone who needs marketing or web design needs that you think Unthink and refer us ;)
