The 2011 version of this article was a classic SEO listicle — meta tags, keyword density, exact-match domains, link directories. About half the items aged poorly. Here's the 2026 version, with the dead ideas pruned and the survivors updated.
The five that genuinely move rankings
1. Pages that answer a real question
Google's actual job is to return the page that best answers a searcher's question. If your page does that — clearly, concisely, completely — you'll rank. If it doesn't, no technical optimisation rescues it. This is the foundation. Skip it and the rest is decoration.
2. Clean page titles and H1s
Both should match what someone would actually type into Google. "Plumber Rathmines | Quick Response, Fixed Pricing" beats "Welcome to McConnell Plumbing." The page title is the single most-weighted on-page signal Google uses; treat it accordingly.
3. Internal linking discipline
Every page should link to two or three thematically related pages elsewhere on your site. This spreads ranking authority around and helps Google understand your structure. Underrated; consistently impactful.
4. Real external links from sites in your category
One link from a respected Irish industry publication is worth fifty from auto-generated directories. (See: How to build inbound links for the 2026 tactics that actually work.)
5. Page speed and mobile usability
Slow sites rank worse. Sites that don't work on mobile rank worse. The 2026 baseline: Largest Contentful Paint under 2.5 seconds, Cumulative Layout Shift under 0.1, mobile-friendly across every page. Test on PageSpeed Insights.
The three that quietly help
6. Local signals (Google Business Profile + NAP consistency)
For a local Irish business, claiming and properly filling Google Business Profile is the single highest-leverage free thing in SEO. Pair it with NAP (Name, Address, Phone) consistency across the major Irish directories.
7. Structured data (JSON-LD)
Schema.org markup for your business type, services, opening hours, articles, FAQs. Helps Google understand the page beyond just the words. Particularly valuable for Local Business, Article, FAQ, and Product schemas.
8. Updated content
A page updated this year usually outranks a page last touched in 2019, all else being equal. The "freshness" signal is real and often underrated. An annual review pass on your top 10 pages costs little and pays back.
The two nobody talks about but absolutely matter
9. llms.txt and AI-search readability
By 2026, classical search engines aren't the only crawlers reading your site — Claude, ChatGPT, Perplexity, and the Google AI Overviews are too. A small llms.txt file at the site root summarising your structure helps these systems quote you accurately. Semantic HTML helps further. (See ours at /llms.txt.)
10. Boring technical hygiene
HTTPS with a working certificate. A clean sitemap.xml. A robots.txt that doesn't accidentally block important content. Canonical tags on every page. No duplicate content across URLs. No broken internal links. No orphan pages. None of these alone are exciting; collectively they're the difference between a site Google trusts and one it doesn't.
What the 2011 list got wrong
The original 2011 version included "meta keywords," "keyword density," "exact-match domain magic," and "submit to 100 directories." Every one of those has either been ignored by Google for over a decade or actively penalised. If you see a 2026 SEO article still recommending any of them, you're reading a copy-paste of fifteen-year-old advice.
