Frequently asked questions

How long should a title be?

About 10–60 characters so it isn't cut off in search results; descriptions about 50–160.

Does it check the whole site?

One page at a time; check your most important pages individually.

Which pages can it read?

Public web pages that return HTML. Pages that need a login, private network addresses and pages built entirely with JavaScript can't be read.
