Raw-HTML crawlers miss the JavaScript-rendered web. A hands-on comparison of Playwright, Puppeteer, and Selenium for SEO automation — rendering JS pages, capturing Core Web Vitals, and crawling at scale, with working code.
Missing alt text starves Google Image Search and multimodal AI of the one signal they need. Here is a working Python + n8n pipeline that inventories, generates with a vision LLM, quality-gates, and writes back image alt text at scale.
Which scraping backbone should power your SEO data pipeline? A production teardown of Bright Data, Apify, and ScraperAPI across SERP collection, competitor crawling, and structured extraction — with code, failure modes, and a cost-per-record model.
Catch crawled-not-indexed and deindexed pages before they cost you traffic. A read-only Python + n8n pipeline that inspects your whole sitemap on the free Search Console quota and alerts on Slack.
An automation-first comparison of Screaming Frog CLI, Sitebulb, and a custom Scrapy crawler for unattended technical SEO crawling pipelines.
A production programmatic SEO pipeline in n8n + Python: enrichment that creates uniqueness, a quality gate that refuses thin pages, per-page JSON-LD, and an indexing controller that lifted indexation from 30% to 88%.
Treat a competitor’s programmatic SEO site as a black box and take it apart with Python: map the URL footprint from sitemaps, fingerprint the template, reconstruct the internal link graph, and estimate what actually ranks.
Pull p75 Core Web Vitals field data from the free CrUX API, detect regressions across your URLs, and fire Slack alerts with a self-hosted Python and n8n pipeline.
GSC, SEMrush, and Ahrefs look interchangeable for a custom rank tracker and are anything but. A developer teardown of measured vs modeled positions, the code, the quotas, and the cost.
Spreadsheets break past a few hundred URLs. Use OpenAI embeddings, Search Console overlap, and an n8n workflow to flag cannibalization across thousands of pages, score severity, and pre-classify each pair as merge, differentiate, or canonical.
