Evaluating the Quality of a Guest Post Site (Traffic, Spam Score, Editorial Standards)

You can evaluate a guest post site by combining hard metrics (traffic, authority, spam risk) with manual review (editorial standards, relevance, UX). Use this as a practical checklist.

1. Check authority & spam risk

a. Authority metrics (baseline filters)
Use one or two trusted tools (Moz, Ahrefs, Semrush, Serpstat, etc.):

• Domain Authority (DA) / Domain Rating (DR) / similar score
  • Many practitioners look for DA/DR ≥ 20 as an absolute minimum.
  • For quicker SEO impact, aim for DA/DR ≥ 30.
• Backlink profile quality
  • Look for relevant, natural backlinks from real sites; avoid sites with most links from obvious directories, PBNs or foreign‑language spam.

b. Spam indicators (red flags)
Even if DA/DR is high, avoid sites that show:

• Irrelevant or over‑commercial anchor text pointing in and out (casino, CBD, crypto, loans across every page).
• Backlink spikes then sharp drops in organic traffic (suggests penalties or paid link abuse).
• Many links from low‑quality or deindexed domains.
• A DA under ~25 combined with aggressive monetisation is often cited as a bad sign for guest posting.

Use spam‑score features (Moz, Ahrefs, etc.) as signals, not absolutes: high spam scores + visible spam patterns = avoid.

2. Evaluate organic traffic (not just “any” traffic)

Use Similarweb, Ahrefs, Semrush, Serpstat, etc.:

• Monthly organic traffic
  • For DA/DR ~20: at least 100–150 organic visitors/month.
  • For DA/DR ≥40: at least 400–500 organic visitors/month to avoid “fake authority”.
• Traffic trend
  • Prefer steady or growing organic traffic over the past 6–12 months.
  • Avoid domains with a big recent drop in organic traffic (could indicate penalties or major quality issues).
• Traffic sources
  • A healthy profile has a good search share; sites relying mostly on referral/spam traffic are risky.

3. Check engagement & audience fit

You want real readers in your niche, not just a metric number.

• Niche relevance
  • Site should be in the same or closely related industry and attract an audience similar to your target customers.
• On‑site engagement (use your tools + manual check):
  • Look for reasonable bounce rate, session duration, pages/session; higher engagement implies real interest.
  • On the site itself: comments, social share counts, internal linking, recent posts with activity.
• Social signals
  • Articles (especially recent ones) receive some shares/interaction; this suggests a content distribution strategy, not just link selling.

4. Review content quality & editorial standards

This is where you separate real publications from guest‑post farms.

Content quality

• Articles are well‑written, coherent, and mostly free of obvious grammar errors.
• Content is original, specific, and helpful, not spun or generic.
• Topics are relevant and consistent with the stated niche.

Editorial standards

• Look for:
  • Clear contributor or writer guidelines (length, quality expectations, link rules, tone).
  • Evidence of a review/editing process: bylines, editor names, consistent formatting, edited headlines.
  • A reasonable publishing frequency: not dead, but not dozens of thin guest posts per day.
• Red flags:
  • “Write for us – dofollow backlinks – $X” style pages.
  • “Guest Post” in almost every recent article title.
  • No guidelines and they accept almost anything you send.
  • Payment required to post purely for links (common indicator of a link farm).

5. Assess monetisation & user experience

Quality sites balance monetisation and UX; low‑quality ones aggressively chase ad or link revenue.

UX checks

• Design is modern enough, mobile‑friendly, and loads at a reasonable speed.
• Navigation is logical; categories and tags are not obviously stuffed just for SEO.

Monetisation pattern

• Reasonable:
  • Some ads, affiliate links, or sponsored content but clearly labelled.
• Risky:
  • Too many ads above the fold, pop‑ups everywhere, auto‑play videos.
  • “Advertise / Guest Post” pages that openly sell dofollow links on homepage, sidebar, or any page.
  • Content filled with out‑of‑context commercial links.

6. Link placement & technical SEO considerations

For SEO value, check how your link will likely appear:

• In‑content, editorial links are far more valuable than sidebar/footer/blogroll links.
• Prefer relevant, natural anchor text (not over‑optimised exact match).
• Ensure pages are:
  • Indexable (not blocked via robots.txt or noindex).
  • Using standard canonical tags (not canonicalised away).
• Check how many external links per article there are; dozens of commercial links per post is a bad sign.

7. Quick practical scoring framework

When you review a potential site, you can score like this (example):

• Relevance (0–3) – niche match and audience fit.
• Authority (0–3) – DA/DR vs your baseline, plus backlink quality.
• Traffic (0–3) – organic volume + trend.
• Editorial quality (0–3) – content depth, editing, guidelines, link policies.
• Spam/monetisation risk (0–3) – low ads, no obvious link selling, clean link profile.

Only invest in sites that score 10+ out of 15 by your own thresholds.

If you share 2–3 candidate sites (or their metrics), I can walk through this checklist on each and tell you which ones are worth guest posting on and why.
