The on-page SEO advice that's repeated across most blogs is mostly recycled from years ago. Some of it still works; much of it doesn't. We tested 30+ on-page tactics across client sites through 2025. Here are the 10 that actually moved rankings in measurable ways. Each one is something we still recommend doing, with notes on what makes it work.
1. Title tags written for the searcher, not the keyword
The old advice: pack the keyword into the title. The new reality: titles that read like search results match user intent and get clicked. Click-through rate is now a meaningful ranking signal; titles that earn clicks rank better than titles that simply contain the keyword.
What works: the keyword appears, but the title is structured around what the searcher actually wants to know. "10 On-Page SEO Tactics That Still Move Rankings in 2026" beats "On-Page SEO 2026 Tactics Guide" — same keywords, very different click rates.
2. Internal links from your highest-authority pages
Internal linking is the most-undervalued tactic in on-page SEO. The pages on your site with the most external authority pass that authority through internal links to other pages. Most sites underuse this completely.
What works: identify your top 5-10 pages by external links. Audit them for relevant internal linking opportunities. Add contextual internal links to pages you want to rank. The boost is often visible within 2-4 weeks.
3. Content depth that matches search intent, not arbitrary word counts
The "1500-word minimum" advice is outdated. Google rewards content that fully addresses the search intent — sometimes that's 800 words, sometimes 4000. Content padded to hit a word count actually underperforms because the padding signals lack of focus.
What works: write the answer the searcher needs, in whatever length that takes. For comparison queries, longer. For quick-answer queries, shorter. Match the structure to what would actually satisfy the user.
4. Heading hierarchy that reflects actual structure
H2/H3 hierarchy still matters for how Google parses content. Pages with logical hierarchy outperform pages with random heading usage. The hierarchy should reflect actual content structure, not be sprinkled in for SEO purposes.
What works: every H2 introduces a major subtopic. Every H3 introduces a sub-point within that subtopic. Don't skip levels. Don't use H2/H3 for visual styling.
5. Schema markup for content type
Article schema, FAQ schema, HowTo schema, Review schema. These markups affect how your pages appear in search results and how AI summaries cite your content. Sites with appropriate schema get featured snippets, rich results, and AI citations more often than sites without.
What works: implement schema appropriate to your content type. Use Google's Structured Data Testing Tool to verify it's working. Watch the Search Console data for the appearance changes within a few weeks.
6. Image optimization for both speed and AI
Images affect Core Web Vitals (page speed) and increasingly affect AI search visibility. Sites with optimized images that have descriptive alt text and good file naming rank better and get cited more often by AI search results.
What works: WebP format. Lazy loading. Descriptive alt text written for actual users. Filenames that describe the image content. Width and height attributes specified to prevent layout shift.
7. Updated publish dates for evergreen content
"Updated" content gets a freshness boost in many search verticals. Pages that haven't been updated in 2-3 years often lose ground to newer competing pages, even when the content is still accurate.
What works: review evergreen content quarterly. Make substantive updates (new examples, current data, removed outdated references). Update the publish date to reflect the actual update. Don't fake-update; Google can detect superficial changes.
8. Featured snippet optimization with explicit format
Featured snippets still appear for many queries, and they drive substantial organic traffic. Pages that explicitly format content for the snippet format Google uses for that query often capture the snippet within weeks.
What works: identify what format Google currently shows for your target query (paragraph, list, table, video). Format your content to match. Place the snippet-eligible content high on the page with appropriate heading.
9. Page experience signals that don't require a redesign
Core Web Vitals affect rankings. Most sites can improve LCP and CLS substantially without redesigning anything. Image dimension attributes prevent CLS. Critical CSS in the head improves LCP. Lazy loading below-the-fold content improves both.
What works: run PageSpeed Insights on your top pages. Address the specific issues it identifies. The improvements are often quick wins that don't require front-end engineering.
10. Internal search optimization
Most sites have internal search functionality that's separate from their SEO strategy. Internal search data reveals what your existing visitors are actually looking for — gaps in your content, queries that aren't being addressed by your current pages.
What works: audit internal search query data monthly. Identify high-volume queries that don't have a clear matching page. Create or update pages to match those queries. The pages tend to rank well externally because the demand is visible internally first.
What doesn't work anymore
Some tactics that older guides still recommend should be skipped:
- Keyword density. Hasn't mattered in years. Write for clarity, not for keyword count.
- Exact-match anchor text in internal links. Now appears spammy when overdone. Mix anchor text naturally.
- Long meta descriptions. Google rewrites most descriptions anyway. Write good ones, but don't agonize.
- LSI keywords as a discrete tactic. Modern Google understands semantic relationships; manually inserting "LSI keywords" doesn't help and often hurts readability.
- Excessive internal linking. Pages with 50+ internal links dilute the signal. Quality over quantity.
The order to implement
If you're looking at the list and wondering where to start:
- Audit titles and click-through rates. Quick wins, immediate ranking signals.
- Map and improve internal linking. High leverage, often immediate impact.
- Review heading hierarchy and content depth on top pages. Structural improvements compound.
- Implement schema where missing. Improves SERP appearance.
- Address Core Web Vitals issues. Quick technical wins.
The rest can follow over the next month or two. None of these is novel, but the combination of all 10 implemented properly produces ranking improvements that most sites would consider significant.
The takeaway
On-page SEO in 2026 is about understanding search intent, structuring content to match it, and supporting the user experience with technical fundamentals. The tactics that work are mostly common sense done well. The tactics that don't work are the leftover hacks from earlier SEO eras.
Pick three from the list above. Implement them this week on your top 10 pages. The rankings will respond if the content underneath is solid. If they don't respond, the issue is upstream of on-page work.
