Most ecommerce sites handle out-of-stock products inconsistently, destroying seasonal rankings. The four viable strategies (keep with notice, 301 to category, 410 Gone, 404) each fit specific scenarios. Here's the decision tree and the reindexation implications.
Product schema is non-negotiable for ecommerce. Stars, prices, and availability in the SERP lift CTR 15-30%. But implementation mistakes — schema claiming features the page doesn't show, variant handling, availability lag — trigger manual penalties. Here's the implementation that works.
Category filters are the UX feature with the most SEO footprint. Every filter selection is a potential URL. Most shouldn't be indexed, but the ones with real search intent should. The trade-off between UX flexibility and SEO cleanliness is worth deliberate design.

GEO & AI Search
Generative Engine Optimization, AI search, LLM crawlers, citation strategy.
Perplexity citations don't follow Google's logic. Older domains, .edu and .gov bias, deeper retrieval, and a freshness signal that punishes thin update cycles. Here's the playbook for the second-largest answer engine.
Five vendors now sell AI-answer visibility tracking. The metrics they report don't match. Here's the toolset, the metric definitions worth using, and a manual sampling protocol when budget rules out vendors.
GEO is not a replacement for SEO. It is a sibling discipline that shares technical foundations, diverges on what counts as a win, and forces a different team workflow.
Header tag rules from 2015 (one H1 per page!) mostly don't hold in 2026. Here's what heading structure actually signals to search engines, how to use H2-H6 semantically, and why the modern HTML5 outline algorithm complicates old-school SEO advice.
Image SEO matters most where visual traffic is commercial: ecommerce, travel, food, fashion. Get the fundamentals right (file names, alt text, format, lazy loading) and image search becomes a real traffic channel.
Featured snippets occupy prime SERP real estate — position zero, above organic results. Winning them requires structural formatting that Google's snippet extractor can reliably parse. Here's which formats work, how to structure content, and the queries worth targeting.

SEO Analytics
Measurement, reporting, attribution: GSC, GA4, KPI trees, SEO ROI.
Site-wide traffic charts hide the real story. Group landing pages by acquisition month and you'll see which content compounds, which decays, and where to refresh — with concrete spreadsheet steps.
GA4 confused everybody. GSC stayed honest. Third-party tools fill specific gaps. Here is the full SEO measurement stack — data sources, attribution, KPI tree, dashboards — without the vendor pitch.
A full SEO audit takes weeks. A triage audit takes 2 hours and catches the issues that would otherwise lose another month of rankings while the full audit runs. Here's the structured framework that scales across sites and verticals.
Agency metrics that look good (new client count, revenue growth) can mask declining business health. The metrics that actually predict agency longevity are unglamorous: retention, client LTV, and the underlying engagement quality.
Weekly manual SEO checks catch problems 3-7 days after they happen. Automated monitoring catches them in minutes. The migration from manual to automated isn't about replacing judgment — it's about catching regressions before they compound.
A CDN is usually an SEO positive — faster TTFB, better Core Web Vitals, happier Googlebot. But the failure modes are subtle: bad cache headers, edge personalization gone wrong, bot-throttling at the edge. Here's how to get it right.
Crawl budget is not infinite. For sites over 100k URLs, how you shape Googlebot's behavior determines which pages ever get indexed. Here's a framework, with real numbers.
Most technical SEO audits fail the same way: they generate 80-page PDFs with 200 findings, and clients execute none of them. The audits that move rankings solve for one thing: which of five layers is broken, and which single fix restores the most value.
