Search Engine Optimization (SEO)
What this domain tests
The SEO domain tests whether you can earn organic discoverability. Expect keyword research and search intent, on-page elements, topic clusters and internal linking, technical crawl/index basics, backlinks, page experience, and measurement. HubSpot ties SEO to content strategy: pages should satisfy a searcher’s query and fit a cluster, not repeat keywords.
Core rules and concepts
- Classify intent before choosing a keyword: informational, navigational, commercial, or transactional. A comparison query needs a comparison page, not a homepage.
- Place the primary term naturally in the title tag, H1, URL, and early body copy; write a unique meta description that earns the click. Avoid keyword stuffing.
- Use descriptive alt text, logical H2/H3 structure, and internal links with meaningful anchor text so crawlers and readers understand relationships.
- Build topic clusters: a pillar page covers the head term; cluster pages answer subtopics and link to the pillar. This concentrates relevance and link equity.
- Technical basics: pages must be crawlable and indexable, canonical tags must resolve duplicates, XML sitemaps and robots.txt should be correct, and mobile speed and HTTPS matter.
- Earn links through useful assets and outreach; relevance and anchor-text quality matter more than raw backlink count.
- Measure impressions, CTR, rankings, and conversions, and refresh pages when intent or SERPs shift.
Worked example
A recipe site wants to rank for “easy meal prep.” The SERP is dominated by how-to guides and lists, so the team builds a pillar guide plus cluster pages for “meal prep for beginners” and “weekly meal prep containers.” Each page has a distinct title tag, one H1, descriptive alt text, and links to the pillar with anchor text such as “meal prep guide.” The team fixes a duplicate canonical, compresses images, and adds a sitemap entry. Reasoning: intent dictates format, internal links clarify the cluster, and technical fixes remove crawl and speed barriers.
Traps that cost marks
Ignoring intent and targeting a high-volume term with the wrong page; stuffing keywords; vague anchor text such as “click here”; duplicate pages without canonicals; and treating backlinks as a numbers game. Avoid noindexing pages you need indexed or blocking CSS/JS that renders content.
