seo-keywords-free
Purpose
Free domain authority signal (Ahrefs Domain Rating) for your own sites and competitors, with no API key. Pairs with seo-trends for demand and seo-dataforseo (paid, optional) for real volume/difficulty when a client deliverable needs exact numbers.
When to use
- Quick competitor authority comparison (e.g. ForexGuru.pk vs. babypips.com vs. a local competitor).
- Sanity-checking whether a target keyword's SERP is dominated by high-authority sites (low chance) or weak ones (opportunity).
- Tracking your own domains' DR trend over time by re-running monthly and diffing against
.seo-cache.
Tool
Ahrefs Domain Rating (free, no key)
- Endpoint:
GET https://api.ahrefs.com/v3/public/domain-rating-free?target=<domain-or-url>&output=json
- No auth header needed.
- Returns:
{"domain_rating": {"domain_rating": <float 0-100>, "license": "<url>"}}
- Attribution required if shown to end users/clients: "Domain Rating by Ahrefs" linking to ahrefs.com. Internal use (your own analysis, not published) doesn't require this, but add it anyway to reports you hand to clients to stay safe.
- No documented rate limit, but this is a goodwill free endpoint — don't loop it across hundreds of domains in a tight script. Cache results in
.seo-cache/dr/ and only re-check weekly/monthly.
Workflow
- Pull the target domain + up to 4 competitor domains (from
seo-research or user input).
- Call the DR endpoint for each (sequential, small delay between calls, not parallel).
- Cross-reference with
seo-trends output for the same keyword set — high DR + rising demand = harder opportunity; low DR + rising demand = easier opportunity.
- Cache results:
.seo-cache/dr/<domain>.json with timestamp, so repeated audits show DR movement over time (feeds into the existing drift-monitoring feature).
Script wrapper (suggested location: ${ANTIGRAVITY_PLUGIN_ROOT}/scripts/ahrefs_dr_free.py)
See ${ANTIGRAVITY_PLUGIN_ROOT}/scripts/ahrefs_dr_free.py wrapper which can be executed:
import requests
def get_domain_rating(target: str) -> :
resp = requests.get(
,
params={: target, : },
headers={: },
timeout=,
)
resp.raise_for_status()
resp.json()[]
