Chapter 23 — Further Reading

Read primary sources first. On links especially, the internet is thick with confident advice from people selling link-building services; Google's own documentation on what it does and doesn't reward is the anchor. Items are grouped by how much you can trust them, in the spirit of the chapter.

Tier 1 — Canonical (start here; free and authoritative)

• Google Search Central — "Link spam policies" (part of the Spam policies for Google web search). Google's own account of what counts as manipulative link behavior — buying/selling links, excessive exchanges, and links "intended to manipulate ranking." The essential reference for understanding why earning beats building, straight from the source that judges it.
• Google Search Central — link best practices ("Qualify your outbound links" / rel attributes). The documentation on nofollow, sponsored, and ugc — the attributes that determine whether a hard-won press link passes authority. Read it before you assume any link is "followed."
• Google Search Central — "Creating helpful, reliable, people-first content." Not a link document per se, but the clearest statement of Google's position that genuinely useful content is what "naturally gains popularity" — the philosophical basis for the whole earning mindset.
• Google Search Central Blog — Google's public statements on link building as a primary strategy. Google has repeatedly, publicly, downplayed active link building and emphasized earning; reading these in Google's own words inoculates you against the industry's opposite message.

Tier 2 — Reputable secondary (useful, but verify against Tier 1 and note the seller's incentive)

• Backlinko — the Skyscraper Technique and Brian Dean's link-earning write-ups (Case Study 1). The original, public articulation of a real method. Read it for the sound workflow — and read it critically, remembering it is also marketing for its author's methods, and that the outreach step decayed into spam (the chapter's point).
• Large-scale content-and-links studies from SEO tool vendors (for example, analyses by Ahrefs, Moz, BuzzSumo, and Semrush of how many pages earn zero links and which formats earn the most). These consistently find that the large majority of pages earn few or no referring domains and that original research and tools earn disproportionately — a robust direction. Treat the specific percentages as vendor figures, not laws, and never quote an exact number as fact.
• Digital PR resources from practitioners and agencies. The best of these teach data-led PR (build the asset, pitch the story) rather than "please link to us" outreach. Filter for the ones that lead with the asset, not the email.
• Reputable industry coverage of HARO's rebrand to Connectively and its 2024 shutdown (Case Study 2). Trade-press reporting on the acquisition trail and closure — useful for seeing platform impermanence documented rather than asserted.

Tier 3 — Current tools and constructed examples (for practice; expect the tool names to change)

• Journalist-request platforms that replaced HARO — Qwoted, Featured (formerly Terkel), SourceBottle, ProfNet, and journalists' direct requests under tags like #JournoRequest. Named here as of writing; expect churn, and remember the chapter's lesson: the skill transfers, the platform is rented.
• Google Search Console — Links report. Free. Your honest, if approximate, source for referring domains and top linked pages over time (§23.6). The place to set your baseline today.
• Constructed teaching examples: Rivertown Home Services' "Metro Home-Services Cost Report" (Figure 23.7) and Figures 23.1–23.6 — all illustrative; the mechanisms (citation obligation, the newsjacking window, lumpy referring-domain growth) are the real lessons, the numbers are not.

Suggested order

1. Read Google's Link spam policies and the rel attribute documentation first — twenty minutes that will make you immune to most link-building sales pitches.
2. Read the Skyscraper Technique write-up (Tier 2) with Case Study 1 open beside it, so you see both the sound method and its decay at once.
3. Skim one vendor content-and-links study for the direction (most pages earn no links; data and tools earn most), ignoring the exact percentages.
4. Open your own Search Console Links report and set your referring-domain baseline — the single most useful thing you can actually do from this chapter today.

The habit to keep building: whenever someone offers you links — a service, a "study," an outreach system — ask "is this earned or built, and which tier is the evidence?" If the honest answer is "built," assume Google will eventually treat it as such, and act accordingly.
