About a week ago I got rid of infinite scroll for icons on Iconify website.
Didn't realise how bad it affected SEO until I looked at search performance emails.
Last month: 192k impressions, 4.43k clicks
2 years ago: 2.07m impressions, 106k clicks.
Infinite scroll was such a bad idea!
After implementing it I did see a drop in stats, so did everything I could to fix it, but it was just unfixable. Then gave up and decided to rewrite it later when I'll have free time. Took way too long to do it. Website basically dropped off the search index.
Good news is, just a week after releasing new website search index is very quickly improving: number of indexed pages, impressions and clicks are all going up very fast.
Don't make the same mistake. Don't implement fancy features that might break SEO. Good old pagination is much better.
