Are you using high quality images in your articles or posts? You actually should do that since Google seems to be rejecting posts with poor images.
Because of non-compliance with image guidelines, Google have rejected posts. Some local SEOs reported.
To be relevant, photos or videos must be taken by users at the location in question. Stock imagery, or photos or videos taken by other parties, are not relevant and may be removed. If the primary subject of the content is irrelevant to the location, it may be removed.
