Alan Bleiweiss: It depends. Is there a way for Google bot to access content without having to go through the Captcha?
Dawn Anderson: No, but it might affect conversions slightly
Cristian Caballero: Hahaha if captcha is annoying, UX is bad, then your visitors will end the visit early and as a consequence your SEO will go worse.
But if it’s a friendly captcha, it doesn’t matter 🙂
Tatsat Savsani: I am not sure about seo factor but it surely killed my pagespeed showing leverage browser cache for Google captcha extrnal link... I only had it on registration and contact page
Adam John Humphreys: Be sure to appropriately tag areas like print pages with rel=nofollow but read up using only where necessary.
Captchas slow down our ability to accomplish things. Studies have shown people are more likely to spend money on sites that make the user experience easier. In fact, the study showed people will pay a higher price for a better experience. The most apprehensive generation around tech the boomers has the highest spending habits of anyone online. Amazon has 1 click checkouts and lightning fast load times. You know exactly what you are getting and how long it will take to get to your house all on a single page. Our job as SEOs is to connect and structure sites to get the most value from a business so the searcher gets what they want while everyone benefits. Most major sites have recaptchas but the old school captchas with the numbers should absolutely not be used anymore. They waste our time and frustrate users.
Dumb question: does Catpcha affect site ranking and traffic or not?
