Technical SEO Implementation Checklist

I use this checklist before publishing or materially updating an article. It is deliberately narrower than a general SEO guide: the question is whether the URL I am about to release has a sound technical baseline. Search Console results, indexing decisions, and ranking changes come later. They cannot be signed off in a pre-publish checklist.

To make the checks concrete, I inspected the currently published version of this Technical SEO checklist page on October 8, 2026.

The release gates I would run

1. Check the response and source. The public URL returned HTTP 200, and the article text appeared in the HTML response. If a preview works but the public page redirects unexpectedly, errors, or ships an empty article shell, I stop and inspect the WordPress output before treating the release as complete.
2. Compare the page identity. This page’s live <title> is “Technical SEO Implementation Checklist – SeoGeo Tech”; its H1 says “Technical SEO Implementation Checklist”; the canonical element points to this URL. These fields need not be identical, but they should describe the same page. If the canonical pointed elsewhere, I would trace the template or SEO plugin setting rather than edit the prose to hide the mismatch. The live metadata check shows that deeper investigation.
3. Check crawl and index directives. The current robots.txt does not block the article path and points to /sitemap.xml. The sitemap index leads to /page-sitemap.xml, which lists this article URL. I also checked the live HTML: its robots meta tag says index, and the HTTP response has no X-Robots-Tag header. A page can return HTTP 200, be allowed by robots.txt, and appear in a sitemap while still carrying noindex in an HTML meta tag or X-Robots-Tag response header. These checks do not prove Google has crawled or indexed it. If the URL were absent from the sitemap, I would check the WordPress sitemap settings and public page status; the robots and sitemap inspection goes through that route in detail. Google’s noindex documentation explains the two directive formats.
4. Look for a usable article, not just passing tags. I check that the main answer, headings, and useful links are present without requiring a browser script. The illustrative image has width and height attributes in the published HTML, giving the browser intrinsic dimensions that can help reserve layout space. If content is missing or a figure breaks the narrow layout, I fix the page before publishing. On mobile I still need to look at the actual rendered page.
5. Inspect generated data only where it makes a claim. I check any Article JSON-LD against the visible title, author responsibility, image, and dates. A valid JSON object is not enough if a plugin and a publishing script disagree about those facts. I documented one such author-type mismatch on another page.

A small command-line starting point

url='https://seogeo.tech/articles/technical-seo-implementation-checklist/'
curl -L -o /dev/null -w '%{http_code} %{url_effective}\n' "$url"
curl -L "$url" \
  | grep -Ei '<title>|rel="canonical"|<h1'

These commands show the response and selected source lines. I inspect the rendered page separately, then use Google Search Console to check Google’s observed indexing state.

Where this checklist stops

For SeoGeo Tech, local static output and the public WordPress page are two different things. The local build tells me what my source produces; the live URL tells me what readers and crawlers receive after WordPress, the theme, and the SEO plugin have added their output. I check both, then use the narrower post-publish QA process after the update goes live. Google’s SEO Starter Guide makes the same point about outcomes: there are no changes that automatically rank a site first, and not every SEO change produces a noticeable result.
