How would you grow this product?

Hi!

I'm running PDFShift (https://pdfshift.io), an HTML to PDF conversion API for a business that needs to automate this.

I compete with other similar SaaS but also against library (like Weasyprint for Python, mPDF for PHP, etc) and software (like WKHTML2PDF).

My main sources of acquisitions right now are Quora (I've answered tons of questions) and AlternativeTo. I have great reviews on Capterra, G2Crowd, and AlternativeTo with at least 4.5/5 stars, which I mention on the website.

I'm working with Google Ads since I believe it's the best place for me to be (people are interested in my service when they need me the most, hence the results of a query like "how can I convert HTML docs to pdf in php") but they doesn't show great results so far... - I'm working on improving them as of now.

Even though content marketing sounds great, I don't have much to say regarding converting HTML docs to PDF: it's a pretty basic tool.

That's why I'm turning to you, masters of growth, to help me figure out to grow the business to 5K, 10K and beyond.

Thank you in advance for your awesome inputs :)
