I've been learning backlinks: a plain-English tool list + glossary

I've been learning backlinks lately.

The hardest part wasn't the outreach. It was the jargon — DR, AS, nofollow, referring domains — everyone uses different words for the same ideas. I cleaned up the tools I keep reaching for, then the terms that actually change decisions. Vendor prices move, so double-check official pages before you buy anything.

Tools first: keyword research and link research

Before you chase links, you need to know which queries you're competing for and where competitors get links. Here's a practical stack: free, freemium, then paid-with-a-free-window.

Free

Freemium (enough to start)

Paid (still some free access)

Zero-budget combo

• Layer 1 (all free): GSC + Keyword Planner + Trends + Google suggest / People Also Ask — real Google-side signals, enough to start.
• Layer 2 (rotate free quotas): Ubersuggest (about 3 queries/day) + AnswerThePublic (about 3/day) + Ahrefs free tools (about 25/month) — rotate them and you can cover a competitor keyword pass in a week.
• Layer 3 (pay later): Ahrefs Starter or Semrush once the free path is working.

Cheap competition check: Google intitle:your-keyword and look at what's ranking. Lots of inner pages, thin results, but high ad bids often means the opportunity is still quiet.

Link research tools I keep seeing

• Ahrefs — Domain Rating (DR); free Backlink Checker at ahrefs.com/backlink-checker.
• Semrush — Authority Score (AS); Backlink analytics with All / Best / New / Lost; Backlink Gap to find referring domains competitors have and you don't.
• Moz — Domain Authority (DA) and Spam Score; DA is free at moz.com/domain-analysis.
• SimilarWeb — total traffic and country mix (includes ads and direct visits; less clean than organic) — useful for cross-checks.
• Google Search Console — indexing, queries, manual actions; URL Inspection can request indexing.
• Bing Webmaster Tools — underrated free look at competitor backlinks.
• Wayback Machine — domain history snapshots at web.archive.org.

Then the dictionary: backlink terms in plain English

Basics

• Backlink — another site links to yours. A trust vote. Published ≠ indexed. Confirm with site: or Search Console before you celebrate.
• Internal link — links between your own pages; helps crawlers understand structure and pass equity.
• Anchor text — the clickable words. Brand-led anchors look natural; stuffing exact-match keywords into every link is how you get ignored or worse.
• Indexing — Google stored the page. Only indexed linking pages really count.
• Referring domains — how many different websites link to you. Ten sites once usually beats one site ten times.
• Link farm / scraper sites — bulk low-quality link pages. Buying a pile of these can hurt more than help.
• Outreach — emailing site owners for links. It's sales: find leads, qualify, talk one-to-one.
• Directories — list sites that catalog tools/products; easy for new sites, still verify quality before you pay.
• Guest post — you write on someone else's site and include a link. Bulk thin guest posts with optimized anchors are in the spam playbook.
• UGC — forums, comments, Reddit — often nofollow.
• E-E-A-T — experience, expertise, authoritativeness, trust. Real data and named expertise get cited more naturally.
• Linkable asset — research, reports, free tools, templates, charts other people want to cite.

Scores (don't trust one number)

• DR (Ahrefs) — 0–100 from link graph signals; easy to inflate; ignores traffic and content quality.
• DA (Moz) — older domain score; fine as a side check.
• AS (Semrush) — blends link quality with organic traffic, rankings, and content health; harder to fake; a better “is this link worth it?” signal.
• DR vs AS gap — if DR − AS is over 30, treat the DR as fluff; over 50, usually junk. Example: twelve.tools at DR 81 vs AS 19 (gap 62) fails the smell test.
• KD — keyword difficulty (0–100); helps new sites pick fights they can win.
• Organic traffic — visits from unpaid search. If a site's organic is tiny (say under ~50/month), a shiny DR still doesn't buy much.
• Spam Score / Toxic Score — risk hints, not automatic Google penalties; still walk away from same-IP template farms.
• Link equity (“juice”) — authority flows through links; a page with hundreds of outbound links dilutes each one.

Link types and cleaner tactics

• Dofollow — default; can pass equity.
• Nofollow — often doesn't pass equity; can still send real visitors.
• Sponsored / UGC — paid placements should be marked sponsored; user content ugc. Skipping the label is the shady path.
• PBN — private blog networks built to pump equity; actively fought.
• Sitewide footer/sidebar links — look big, usually weak; body links matter more.
• Resource page links — natural placements on “best tools / resources” lists.
• Broken link building — find 404s on other sites and offer your page as the replacement.
• Skyscraper — make a stronger version of a linked piece, then ask sites linking the old one.
• Journalist request replies — earn news links when you're quoted.
• Paid links — before you pay, check AS, organic traffic, and indexing. High DR + low AS + almost no organic is usually a tax on impatience.
• Forced reciprocal links — “link me or no listing” — skip.
• Backlink Gap — map referring domains competitors have that you don't.

Risks

Link spam policies cover buying links at scale, mass exchanges, automated spam, and thin guest-post schemes. Filters ignore a lot of manipulative graphs. Bad neighborhoods can splash onto you. Manual actions may show in Search Console as unnatural links. Disavow carefully — it's easy to overdo. New or shady domain histories (check Wayback) deserve skepticism.

Platforms people mention

Quality directories should be judged by AS, DR, and organic together — expensive can still be worth it; inflated scores shouldn't be. Stripe Climate can create a high-DR page as a side perk — a tip, not a strategy. Reddit and Medium can help with exposure if you're not spamming. A Chrome Web Store listing can be a long-lived asset with a site link.

Before you pay or pitch, ask three things

1. What's the AS?
2. Is there real organic traffic?
3. Is the linking page indexed?

Backlinks aren't a score-buying game. Learn the tools and the words first — then decide who to ask and what to pay.
