How to build backlinks with this list

Four steps that work for a new site, a SaaS or a side project. No paid link packages, nothing that risks a penalty.

  1. Get the basics right first

    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.

  2. Claim profiles and free listings

    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.

  3. Go after a few strong links

    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.

  4. Track and keep it clean

    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

A link opportunity is not a link.

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.

Common questions

Do backlinks still matter for ranking in 2026?
Links remain one signal among many, and low-quality bulk links do more harm than good. What still works is being listed where your buyers actually look — directories with real traffic, registries your peers use, and launch platforms with engaged audiences. Every entry in this list is a place a human might plausibly find you, which is why they are worth submitting to regardless of link equity.
Which submissions should I do first?
Start with the quick wins filter: free, low effort, and not in the lowest priority band. 208 of the 1,964 entries qualify, and those are the ones where a single form submission gets you a live listing the same week. Launch platforms are worth saving until your product is genuinely ready, because you only get one good attempt at each.
How is the impact score calculated?
It starts from a hand-assigned priority band (do first, high, medium, later), then adjusts for cost and effort. A free, quick opportunity scores above a paid, involved one in the same band, because it is the one you can realistically finish today. The score is a queueing aid, not a measure of domain authority.
Are these links free?
1,628 of the 1,964 entries are free to submit to or offer a free tier that includes a listing. Cost is shown on every row, and the "nothing to pay" filter narrows the list to exactly those.
Which backlink sites are dofollow?
44 entries are known to give a followed link on a normal listing, and more give one only in some placements. The link type is shown on every row and can be filtered. Sites change their link policy without notice, so treat the label as a starting point and check the live page after you are listed. A nofollow link from a busy site still sends visitors and helps search engines discover you.
What does the DA number mean?
It is our estimate of the site's domain authority, a third-party style 0-100 score of how strong a domain's link profile is, rounded to the nearest 5. 1,580 of the 1,964 sites have one. It is useful for comparing sites, not a Google metric, so relevance to your niche still matters more.

Will submitting everywhere hurt my site?
Submitting to spam directories can. That is why this list is curated rather than scraped, and why entries carry a status showing whether they have been verified as live. Skip anything that promises hundreds of links for a fee, and prefer places where a real person reviews submissions.
