Hello

I uploaded my website (stephenhousedental.co.uk) and submitted to Google Mobile friendly test.
Few issues reported such as "Googlebot blocked by robot.txt), mobile usability - Text too small to read, clickable elements too close together etc. I used font size 15/14 for headers and rest size 13. Still it shows text too small to read. Any advice, suggestions?

thanks in advance.

It is possible to use a different font size in breakpoint for mobile devices.

OK.
Any idea what is meant by "Googlebot blocked by robot.txt"?

thanks

It means that the robot.txt you have added is incorrectly configured and that you are disallowing the bot to read the page / content. When using the likes of a robot.txt please ensure that you configure it correctly or the web crawlers won't be able to read your site and you will continue to get this error.
