SEO strategies that drive organic growth in 2019

Executive overview

Most SEO advice chases the latest algorithm update. The strategies that consistently work are older than any update: topical authority, search intent matching, and link quality.

Keyword-level targeting underperforms because Google ranks pages for thousands of queries at once. The winning approach is to own a topic, not a keyword.

Build topical authority through content silos, match search intent before anything else, and prioritise links that are hard to get.

Mobile-first and topical research

• Google uses mobile-first indexing for over half of search results — a non-mobile site is a ranking liability.
• Targeting individual keywords misses most traffic potential.
• The top-ranking page for any query ranks for ~1,000 additional keywords on average.
• Find topics with breadth by looking at competitors' top pages in Site Explorer: compare traffic volume to the top keyword's volume — the bigger the gap, the greater the potential.

Building topical authority

• Google favours sites that dominate a niche over generalist sites covering many topics.
• A site with more backlinks can still rank below a topically stronger competitor.
• Two ways to build topical authority:
  • Get links from topically relevant, authoritative domains in your niche.
  • Build content silos: a top-level page for the head term, with subtopics that interlink, creating relevance for users and search engines.
• Use Keywords Explorer's Phrase Match report to identify subtopics around a seed keyword; the Parent Topic column surfaces what the top-level page should target.

Matching search intent

• Search intent is the reason behind a query — Google's primary job is to match results to intent.
• Links, technical SEO, and on-page work don't compensate for a page that misses intent.
• Identify intent by examining what already ranks; results fall into the three C's:
  • Content Type: blog post, product page, category page, or landing page.
  • Content Format: how-to, step-by-step, list post, opinion editorial, tool/calculator.
  • Content Angle: the hook or benefit angle in the title.
• Correcting intent alone moved one Ahrefs page from position 40 to position 6 in four days.

Keeping content fresh

• Google applies a freshness factor in its ranking algorithm.
• Republishing older content produces measurable organic traffic gains without additional link building.
• Before refreshing a page, check four things:
  1. Is it older than 6–12 months? If not, give it more time.
  2. Does it have enough links to compete? If not, it's an authority problem, not a freshness one.
  3. Does it match search intent?
  4. Did it rank well before but is now declining — and is the content outdated?
• A clear signal: competing pages in search results carry the current year in their titles and yours does not.

Links that move the needle

• Not all links are equal — harder-to-earn links provide more SEO value.
• Evaluate link quality on three criteria:
  • Topical authority of the referring domain: links from sites in your niche carry more weight than tangentially related sites.
  • Relevance of the linking page: a link from a page on the same topic outweighs one from a page that mentions the topic in passing.
  • Link authority of the referring page: measured by URL Rating (UR) — higher UR passes more PageRank.
• Two tactics that reliably hit all three criteria: the skyscraper technique and guest posting on handpicked sites.

YouTube SEO as a Google SEO lever

• Video results are taking more Google SERP real estate — and that share is growing.
• Ahrefs grew YouTube subscribers 3x and views 10x in one year; Google traffic to those videos grew consistently.
• Ranking videos in YouTube for competitive terms (SEO tutorial, YouTube SEO) also surfaces them in Google search.
• Treat YouTube as a second search channel, not a separate content strategy.
