It is true that SEO agencies with expert knowledge have dedicated teams to resolve manual penalties. If a page does not comply with Google's quality guidelines, it is subject to manual penalties. In either case, your content may be omitted from search results or your rankings will be lowered.
We can assist you in determining why your website was penalized, fixing the problem, and applying for a reconsideration review.
In the event that you do not meet Google standards, work with Google to have the penalty removed, and then launch an SEO campaign to restore your search ranking and rebuild the authority of your site.
