Post Frequency shows an overall number of posts per week.
It's essential to keep post regularity on the same level, nevertheless, it's not recommended to spam the audience with 5 posts per day.
Select influencers who don't post too frequently (around 5-6 times a week). In case a blogger is posting several times a day, it is good to agree for an advertisement post to be the only one of the day, as it will increase engagement. It is better to avoid those who advertise a product in every post. On average, there should be more regular content than advertising.
