In my opinion, the most important way to let yourself know is through networking. As an IT Professional for over 20 years (way before social media sites) I’d seen how human interaction has evolved, but the basics remain the same. Everyone wants to get known and recognized and if you want to get yourself or your product/services out there, you have to network with others respectfully and also help others. Networking is not a one-way street, you have to contribute by collaborating with others. This is how you get to promote yourself or a product/service.
Lets say, for example, that you refurbish and resell used smartphones out of your home. You could use a blog to attract visitors to your website where you list your current phones for sale. Your blog might cover topics about DIY refurbishing. On one level, it seems counterintuitive because you want people to buy your phones, but it also helps you build a brand and gain recognition. Social media guru Jay Baer explains the concept on Copyblogger:
If you want to really make money with your blog, you need to create a mailing list using one of the billions of email service providers out there. I use and love ConvertKit, but if you are just getting started and don’t understand sales funnels, sequences, or tagging you might want to start off with something simpler and free. If that is the case go with MailChimp where you get the first 2,000 subscribers free or Mailer Lite.
Allow readers to purchase your own products or donate to your cause through your blog. If you have an online store for selling arts and crafts, or you create T-shirt designs available through a clothing website, provide links to those sites. Including a PayPal button for quick, safe purchases or donations is a common way to monetize creative blogs, or blogs that provide free advice or assistance to those who can't afford it.
If you’re passionate about something, it will show in your content. Readers will be able to see your genuineness and will be attracted to that. This is probably the most important thing you will learn about blogging. You can try everything in the world and use every tool known to man to be successful, but if you’re not genuine, people will see right through it.
