Why Robots.txt, Sitemaps and Metadata Still Matter
In an era of headless CMSes and JavaScript frameworks, it's tempting to
dismiss plain-text files like robots.txt and sitemap.xml as relics. They
are not.
robots.txt
A plain-text file at the domain root that tells well-behaved crawlers where
not to go. Not a security control — malicious bots ignore it. But it's often
the quickest way to enumerate interesting paths a site would rather you
ignore: /admin, /staging, /drafts. Audit yours.
sitemap.xml
A hint to search engines about the URLs you want crawled. Especially useful for large sites, frequently updated content, or pages not well-linked from the homepage. Check it periodically — stale sitemaps with broken URLs hurt ranking and credibility.
HTML <head>
Canonical URLs, <meta name="robots">, Open Graph tags and Twitter cards
decide how your content appears in search results and social feeds. A
noindex tag left in place after launch is one of the most common
post-migration bugs. Check yours.
