SEO & marketing: common questions
Do the QR codes expire?
No. They are static QR codes: the content is encoded in the image itself, there is no redirect service and nothing to renew.
Can I create many QR codes or barcodes at once?
Yes. Paste one value per line in bulk mode and download every code as a PNG or SVG in one ZIP file.
Do the meta tag and robots.txt generators guarantee rankings?
No. They produce correct, standards-based markup and files. Rankings depend on your content, your site and search engines.
