SEO Question: Is it better to
 

Populate your new website with 1 big update like 1000 new blog post and never update it again OR
Slowly populate it with 1 blog post per day?

Thanks

Populating in one go or drip-feeding doesn't really make much of a difference, but I would never populate and never update again. Every website needs to be updated from time to time.

Some of our sites we start with 20+ blogs so there is a fair amount of content there then we auto-post every day/week. The sites are always getting updated, even if it's minor tweaks to sentences.

Ok - understand that populating is one thing - the ONLY one's benefiting are your customers assuming they click thru to your site- that being said - how do you project and guess on future keyword changes in analytics?

and if you have that much - why choose one blog - you need to learn how to get around some loopholes on google but it can be done. This isn't going to help either for page ranking either so be careful and always check and modify things to optimize you site

You really do need to speak to your SEO person or someone for better advice

Probably rank differently due to each post anyway so just keep your audience happy and not worry how you trickle it.

This pretty much. Though if the sites are going to be PBN sites, then I may "never update" again as far as blog posts go - but outbound links would happen, of course.

This doesn't really make any sense.

And this.

Slow drip, always. Google keeps track of when a link was discovered for the first time in its crawls so you can expect that date is used as a ranking factor.

Definitely slow drip.
