The secret is finding untapped areas where competition isn’t as fierce—and getting in there before other people recognize it.”

Start Guest Blogging: Since you can't invest in link-building and advertising, guest blogging is your best chance to get high-authority backlinks to your site. It's one of the best content marketing strategies that will continue to pay back even years after your posts are published. Make sure you publish guest articles on relevant high-authority blogs that are aligned with your target niche. Include at least one or two backlinks in your guest posts to your ToFu content and lead magnet. This is how you'll gradually build your audience, add them to your content funnel, and eventually turn them into customers.
