Link Quality Assessment¶

Donor quality evaluation criteria, outreach methodology, PBN (Private Blog Network) usage, drop domain strategies, and link audit procedures.

Outreach¶

Direct contact with sites to buy/negotiate article placement with a link.

Pros: actively pushes queries to TOP; improves whole site through authoritative links; good indexation.

Cons: expensive; time-consuming; hard to control; ~20% chance of being scammed.

Donor Selection Criteria¶

Active link growth dynamics in Ahrefs
Niche-relevant or adjacent + media
DR >= 20, traffic >= 1000, index >= 100 pages
No spam niches (adult, pharma) in index
No labeled "sponsored content" / "advertising" posts
Has queries from your niche in TOP
Good design (not 90s style)
Quality inbound links from content
No spam words in source code
Quality content, regular new articles
Not created solely for selling links

Dynamic Sitewide Links¶

One donor places different links to your site from different pages with varying anchors.

Setup Rules¶

10-20 links to 1 of your pages (from different donor pages)
Different anchors per query cluster
1 link per anchor/query
~30% dilution for Google (URL, brand, toponym)
No duplicate links on 1 donor page
Don't link from ALL donor pages
Max 3-4 "neighbor" sites per donor page
Donor must be authoritative: portals, news sites, regional sites

PBN (Private Blog Network)¶

Managed network of sites for boosting main domain.

When to Use¶

Black/gray niches
High-competition niches
Point boosts for HF/ultra-HF queries in white niches
Not profitable in RU market for most niches

Quality Requirements¶

PBN: DR 5, TF 8, CF/TF > 1.8; web archive preferred
Money site: DR 15, TF 15, CF/TF > 2
Glue: similar to PBN, slightly lower if highly niche-specific

Rules¶

PBN volume <= 10-30% of total link profile (point boost only)
Links must organically fit the site
No PBN on young sites without dilution, especially first 6 months
Don't buy cheap networks from unverified webmasters

Drop Domain Strategies¶

What Drop Domains Are¶

Previously existing but abandoned domains with residual value: age, trust, backlinks, query index.

301 Redirect / Glue¶

Redirect from drop domain to your site. Transfers links, age, trust.

Purpose: boost entire host with link mass; attach domain age; boost promoted page; increase Google trust.

Selection criteria: - Strong domain with links from hard-to-get sources (.gov, niche sites, competitor sites) - Highly niche-relevant (or very authoritative adjacent) - Ideally auction domain (age preserved) - Domain in index and ranking

Testing Protocol Before Applying¶

Buy domain
Find competitor in TOP 20-30 for your queries
Track competitor's positions
Apply redirect to competitor (same way you'd apply to yourself)
Monitor 2-4 weeks
If growth -> redirect to your site
If no reaction -> don't use
If competitor drops -> remove redirect, discard domain

Redirect Setup¶

Install antibot .htaccess on drop domain (block crawlers initially)
301: homepage -> homepage; other pages -> homepage OR by redirect map
Manually redirect pages with strongest links
Option: redirect topically relevant drop to relevant category

Where to Find¶

mydrop.io, expired.ru, reg.ru, nic.ru, dropmonitor.ru
Webarchive parsing via rush-analytics.ru
Backlink parsing from authoritative sites
SERP parsing (top 100 for keywords -> extract domains -> check WHOIS)

Drop Domain Evaluation¶

Verify top 10-15 links still alive (manually)
Links point directly (no chains)
Dofollow >= 60%
Check for Chinese characters (reuse indicator)
Check for link explosions
Pharma, gambling, essay, retail -> skip
Many anchor links -> skip
Web archive exists -> good; check topic change history
Drop count: >2 resets -> bad
Check IKS and query index via Keys.So

Link Audit¶

What to Check¶

Quantity (links, hosts)
Spam and SEO anchors (by hosts)
Link growth dynamics (especially SEO links)
Spam-filled donors actively trading on exchanges
Broken sites, Xrumer links, hidden links
Special attention to new links

Auto-Detection of Link Spam¶

Export from Ahrefs + GSC: 1 link per domain
Check in Screaming Frog (with browser emulation):
Custom Search: regex for your domain links
Custom Search: spam words (viagra|payday|porn)
Reject via Google Disavow Links

Alternative: Rush-Analytics PBN section -> "Spam in links"

Donor Quality Checklist¶

Forum Links¶

Google traffic via Ahrefs >= 100
Indexation > 1,000 pages
Spam check (same as article links)
Forum alive with regular fresh topics
Paid topics should not dominate
Find forums: inurl:forum OR inurl:showthread [keyword]

Link Exchange Platforms¶

Marketplaces for buying eternal (one-time) or rental links.

Rules: - Manual donor selection mandatory - Plan anchors and dynamics based on competitors - No point buying links > 1,500-2,000 RUB - Don't follow exchange recommendations - Don't use "link boosting" (exchange sends bots -> penalty risk)

Platforms (RU): Miralinks, GGL, pr.Sape

Link Analysis Tools¶

Tool	Purpose
Ahrefs	Full backlink database, anchor analysis, dynamics, metrics
MegaIndex	Free RU: SEO vs organic link ratio (>40-50% SEO = warning)
LinkPad	RU market backlink analysis
Majestic	Trust Flow / Citation Flow metrics

Gotchas¶

Always test drop domains on a competitor first - applying untested redirect to your site can tank rankings
20% scam rate in outreach - verify donor quality independently before paying
PBN should never exceed 30% of link profile - use as point boost only
Chinese characters in web archive = domain was reused - usually low quality
More than 2 domain drops/resets = toxic - skip these domains
Link exchange recommendations are unreliable - always select donors manually
