After editing my articles for KW density and content, I've been able to hit page 2 of Google based on content alone. I've had zero backlinks/social signals. My domain is fairly new, so my PA/DA is nonexistent. Is it possible to hit page one at this rate based on content alone? My on page SEO is a lot better than my competitor's, but I feel like they're still beating me because they actually have established PA/DA ranks higher than my pages. How can I raise my PA/DA manually? I've tried looking for related high PA/DA sites to comment on, but their comments are either blocked, manual approval, or Facebook comments. I really don't have to budget to invest in buying high DA niche links at the moment, so is there another way to go about this? The only other thing I can think of is the amount of amazon affiliate links I have on each article. Would having too many be a problem? Is there some sort of guideline I can follow regarding outbound links?
