20+ Quality Blog Posts a Day Too Much For Google?

I want to start a blog with posts that will rank high for various related keywords. There are quality writers available for cheap, which means I can get 20+ quality blog posts a day to the blog.

Will that spark a red flag for Google?

If so, what is the limit of quality posts you should post per day? Or can I get by through gradual posting until I get to 20 blog posts on a day, then just keep doing 20 (i.e. day 1 - 5 posts, day 2 - 6 posts, ... day 16 - 20 posts, day 17 - 20 posts, day 18 - 20 posts ...)?

To me, you can have 20+ quality blog post a day and Google will not penalize you for this.
The question is how many days can you continue, forever? Are quality posts cheap or you have deep pockets?

Nothing is too much

There is no limit but focus on quality rather than quantity

Like the other guys said. There's never too much of a good thing...

Just make sure that it's always a good thing you're posting and you'll be solid. May I mind you, it might be a better idea to drip the posts like 4 a day, just in case you run into the scenario where you can't come up with anything for a while.

Whilst it certainly won't hurt you to churn out high quality blog posts at a rapid-fire rate (20+ a day) I don't know if there are any enormous benefits to this is the long run, either.

It's a case of 'each to their own' but I'd be stockpiling those article and dripping them out at around 3-5 articles a day.

This way you won't shoot your wad in the first 6 days and then have your blog turn into the online equivalent of a ghost town.

If you're scheduling out 3-5 blog posts a day that are legible and offer value to your readers and you have a giant pool of content to draw from then I think this will ensure the longevity of your blog and ensure that readers who actually enjoy your content will always have something fresh to read when they return.
