MyRedLink handles the technical side, but where and how you post still decides your results. A few honest rules of thumb:
Follow each subreddit's rules. Some communities restrict links or self-promotion. Read the sidebar rules before posting; removals hurt your account far more than any link tool can help it.
Give context. Posts and comments that explain why the link is worth tapping outperform bare links.
Use one link per campaign or community. Tag each with its subreddit so your dashboard shows which communities actually convert.
Set a real preview. A clear title and image in Advanced settings makes your link look legitimate in the feed.
You stay responsible for complying with Reddit's content policy and each subreddit's rules.
