Reciprocal Link

When two websites agree to link to each other. While natural reciprocal linking happens organically, systematic one-to-one exchanges at scale can look manipulative to Google. Triangular link-building methods avoid this pattern.

Reconsideration Request

A formal submission asking Google to re-evaluate your site after you've corrected the issues flagged in a manual action penalty. A successful reconsideration request requires documenting the problems found and the specific steps taken to fix them.

Relative URL

A URL path that omits the domain (e.g., /blog/link-building instead of https://example.com/blog/link-building). Relative URLs work within the same site, but for canonical tags, hreflang, and sitemaps, absolute URLs are recommended.

Resource Pages

Curated pages on other websites that compile and link to helpful tools, guides, or references within a topic. Resource page link building involves finding these pages and pitching your content as a valuable addition.

Rich Snippet

A search result enhanced with extra visual information — star ratings, product prices, FAQ dropdowns, or event dates — pulled from structured data on the page. Rich snippets increase click-through rates by making your listing stand out.
