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.
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.
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.

GEO & AI Search
Generative Engine Optimization, AI search, LLM crawlers, citation strategy.
Eight LLM crawlers now hit your site. Some train, some retrieve, some do both. Blocking the wrong one costs you AI-channel visibility for nothing. Here's the matrix and the robots.txt that maps to it.
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.
Topical authority is the ranking signal that rewards depth over breadth. Pillar-and-cluster structure concentrates that signal. Here's how to design, publish, and interlink a cluster that compounds authority over 6-12 months.
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.
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.

SEO Analytics
Measurement, reporting, attribution: GSC, GA4, KPI trees, SEO ROI.
Bounce rate inverted in GA4 and most teams still report it the old way. Here's what 'engaged session' really means, the 10-second threshold, and why engagement rate alone misleads SEO decisions.
Search Console reports impressions like they're a clean count. They aren't. Anonymization thresholds, AI Overview accounting, and SERP feature counting rules quietly distort the number you report up.
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 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.
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.
Hreflang breaks silently. Bidirectionality errors, region code confusion, and mixed delivery methods cause international SEO issues that don't show up as explicit errors — just underperformance in secondary markets.
Core Web Vitals is a real but modest ranking signal — and the metrics keep shifting. INP replaced FID in March 2024. Here's what the current three metrics actually measure, what they don't, and where optimization actually moves the needle.
