Page authority - MetricSpot docs

Q: Why does my Open PageRank differ from Moz DA or Ahrefs UR?

Each tool crawls a different slice of the web with a different algorithm. Open PageRank uses Common Crawl + classic PageRank math. Moz uses its own index and a machine-learning model trained against Google rankings. Ahrefs has the largest commercial backlink index. Treat them as three opinions — directionally similar, never identical.

Q: My new domain is stuck at 0. How long until it moves?

Three to six months of consistent link earning, assuming the links land in Common Crawl's index. New domains under three months old often show 0 even with real backlinks simply because Common Crawl hasn't recrawled the linking pages yet.

Q: Should I buy an expired domain to skip the climb?

No. Google's link spam systems (SpamBrain, the December 2022 link-spam update, and subsequent core updates) specifically target redirected-expired-domain authority laundering. The short-term lift almost always reverses, and the recovery takes longer than building authority honestly would have.

What this check does

Queries the Open PageRank API for your registered domain and returns a score from 0 to 10. Open PageRank rebuilds the classic PageRank algorithm over the public Common Crawl link graph — it isn’t Google’s internal score, but it correlates well enough to be a useful free signal.

MetricSpot reports the raw number and a band: < 3 new/unestablished, 4–6 mid-tier, 7+ well-cited.

Why it matters

Backlinks remain one of Google’s strongest ranking signals. Pages and domains that earn citations from established sites rank faster and weather algorithm updates better than equivalent content on unknown domains.

Paid tools like Moz Domain Authority and Ahrefs URL Rating give a more accurate read with deeper crawls. Open PageRank is a free directional proxy — useful for tracking your own progress month-over-month, sanity-checking competitor strength before a content push, and spotting whether a guest-post target is worth the time.

A new domain sitting at 0–2 isn’t broken. It just hasn’t been cited yet. The fix is link-earning, not link-buying. Expired-domain shortcuts almost always get caught by Google’s link spam systems and tank the recovery.

How to fix it

1. Query Open PageRank directly to sanity-check the score.

curl -H "API-OPR: $OPR_API_KEY" \
  "https://openpagerank.com/api/v1.0/getPageRank?domains%5B0%5D=example.com"

The free tier allows 1,000 requests per day after registration at domcop.com/openpagerank. Plenty for a monthly tracking spreadsheet across hundreds of domains.

2. Pair with dig to confirm you’re checking the right host.

dig +short example.com
dig +short www.example.com

Open PageRank scores the registered domain (eTLD+1), not subdomains. A score for blog.example.com will look up example.com. If your content lives on a subdomain, that’s the number that matters.

3. Build a credible-citation list for a new domain.

Order of effort, highest ROI first:

Industry directories that hand-curate listings — usually a one-time submission with a contact form.
Podcast guesting. Hosts almost always link their guests in show notes from a high-authority root domain.
Original data or research that other writers cite. A single small dataset published under a permissive license can earn dozens of links over years.
Guest posts on niche publications you actually read. Avoid generic “write for us” link farms — Google’s spam classifiers know.
HARO / Qwoted / Featured.com responses. Slow but effective when journalists pick you up.

Skip: paid link networks, expired-domain redirects, comment spam, PBN rentals. The downside-when-caught is permanent.

4. Track progress, not absolute numbers.

Score updates lag the live web by 2–4 months. Run the check monthly and watch the trend. A move from 2 → 4 over six months is real progress; chasing a one-month bump is noise.

5. Cross-reference with on-site signals MetricSpot already measures.

Authority compounds with content depth, a clear internal linking strategy, and visible author attribution. Earned links to a thin site convert worse than earned links to a deep one.
