Question

Macros

Can you please tell me how to write a macro for Excel that would take the URL from cell A1 and check for its presence on the web page whose address is registered in cell B2? And if the link is present, then he created some kind of note - for example, put a plus sign.
text1 mysite.ru/1.html
text2 mysite.ru/2.html
I'm a total noob with macros in Excel :(
