Great question! Think of "Domain Authority" (DA) like your website's reputation score with Google. The higher it is, the more likely you are to show up on the first page when people search.

You can't buy a better reputation - you have to earn it. Here?s how you do that nowadays:
Become a Helpful Expert (Create Amazing Content)
Get Mentioned in the Right Places (Quality Backlinks)
Be a Good Neighbor, link your new article to the old articles (Internal Linking)
Speed and Mobile-Friendliness (User Experience)
