Hi Clara, don’t be discouraged. What you are experiencing is normal. The main reason you aren’t seeing your DA or PA move is due to the types of links you are building. Moz (the company that developed DA/PA) completely ignores links from profile creation, social bookmarking, and generic blogger submissions. Because anyone or any automated bot can create those links instantly, search algorithms and authority checkers assign almost zero weight to them. In many cases, they just end up in the "spam" bucket.
However, if you want to move the needle on your DA and PA scores, you need to shift from quantity to quality. Based on my experience, try focusing your efforts on these three strategies instead:
Content Assets (Linkable Bait): Instead of pushing links out, pull them in. Write comprehensive, data-driven guides or create free tools related to your niche. People will naturally link to you because they naturally link to high-value resources.
Real Guest Blogging: Reach out to active, established blogs in your industry. Write high-quality articles for them in exchange for an in-content contextual link. Honestly, that will really help because one link from a real, high-DA site is worth more than 500 profile links.
Broken Link Building: Find dead resource links on authority websites using tools like Ahrefs or broken link checkers. Email the site owner, politely point out the broken link, and suggest your content as a replacement. Though, authority metrics update slowly and often take weeks or months to reflect new data but It's worth it.
