Soft 404s: When a Missing Page Returns 200 Instead of 404
A visitor mistypes a URL and lands on your tidy "page not found" screen. It looks correct. But if that screen was delivered with an HTTP 200, a search engine just saw a real page where there is nothing - and it may index the emptiness. The words say "not found"; the status code says "here's content."
WordPress Domain Migration: Why Search-Replace Misses Your URLs
You moved the site from staging to the live domain, ran a database search-replace for the old host, and most links updated - but some images 404, a widget points at the old URL, and a page-builder block still loads from staging. The replace didn't fail. It reached one kind of data and silently skipped two others.
ads.txt: The One File an Ad Network Checks Before It Pays You
You finished the site, applied to an ad network, and nothing serves. Often the block isn't your content or your traffic - it's a missing text file at your domain root that the network uses to confirm the ad space is really yours to sell.
Search-and-Replace on Base64 Page-Builder Content: Why It Silently Fails
You wrote a snippet to change one label in a page-builder template, activated it, saw no error - and the old text is still there. The snippet didn't fail. It ran, matched nothing, and reported success. The value you were editing is wrapped twice, and your search string only accounted for one layer.
Why Do Some WordPress Themes Base64-Encode Text?
Open a page-builder post in the code editor and you may find a wall of gibberish where your headings and paragraphs should be: `JTIwJTNDaDIlM0U...`. That's your content, base64-encoded inside a shortcode. It looks like obfuscation for its own sake. It isn't - but the reasons it exists are also the reasons it causes trouble later.
