Frequently Asked Questions
QHow long should my meta description be?
Google typically displays up to about 155–160 characters in search results, though it can truncate or rewrite descriptions based on the query. Aim for 140–155 characters to stay safely within the visible range.
QWhat is the ideal Open Graph image size?
Facebook and most platforms recommend 1200×630 pixels for og:image. Images smaller than 600×315 pixels may not display as large card previews.
QWill a robots.txt file generated here work on any web server?
Yes. The robots.txt format is a web standard supported by all major search engine crawlers and is independent of your web server technology.
QCan I check canonical tags for a live page?
The canonical checker reads from pasted HTML source. To check a live page, use your browser's 'View Page Source' and paste the <head> section into the tool.
