paypal told me that i shouldnt use any characters in the title or pages, just letters and numbers, it mite affect the sale and it mite not go thru do characters affect anything in seo and how search engines see them or rank them
You can just change your Character Encoding settings and you should be able to use characters. This has something to do with the default character encoding used by PayPal for postbacks. But, either way it should not affect your SEO if you decide to stick with the default settings.
It will not Change your ranking or your sale. Paypal used your card information as packets and paypal encrypt this information in Packet forms so when encrypt the information paypal used character and symbol so that's why paypal saying you can't use characters in title. Thanks
