Four steps that work for a new site, a SaaS or a side project. No paid link packages, nothing that risks a penalty.
Before submitting anywhere, have a one-line description, a 150-word description, a square logo and two or three screenshots ready. Every form asks for some mix of these.
Start with the free, quick rows: profile creation sites and free directories. They are one form each and build the entity signals search engines use to understand who you are.
Then pick a handful of high DA and dofollow sites that fit your niche, and write proper guest posts or launch posts for them. Ten relevant links beat a hundred random ones.
Note where you submitted and when. Recheck after a month, update stale descriptions, and never pay for bulk link packages: they put the whole site at risk.
Behind the list
Every row here starts as a line in a sheet, gets normalised into one of 16 groups, scored for cost, effort and impact, and written up with the steps to actually submit. The floor below represents that pipeline.
