Hi, I'm doing a study on hreflang and sites that use it for ccTLD's compared to sub-domains. The objective is to determine what is the optimal strategy for i18n for more traffic: 1: One domain for all languages 2: Subdomains for languages 3: Subdomains for languages and locations 4: Subdomains for languages and ccTLD's for locations 5: Just ccTLD using the language for only one country I have a feeling that option 5 with subdomain for language and ccTLD for location would yield the best results. But to push my project forward I need to do a study and get solid numbers. Methodology: 1 - Get list of sites for each strategy 2 - Get date of implementation 3 - Look at Semrush (api) for those sites for traffic changes since they implemented hreflang ( Semrush has rankings by country) 4 - crunch numbers and see if there are any trends that are emerging ***What I would need is to get a list of sites that used strategies 2 to 5 so far this has been hard to find good implementations (amazon class sites do not count as Google will bend over backwards for them). I would appreciate any help with listing of the sites (in the case of blackhatworld if you could just mention what are the brands that are using it.) *** Any help is appreciated. I will share my conclusions at the end of this study.
