Which of the following statements regarding how marketers should view Google algorithm changes is accurate?

If a marketer receives multiple penalties due to multiple algorithm changes, fixing one of them is enough to regain their original positions in organic results listings.

If a marketer is not notified of a penalty but notices decreased page rankings, the marketer should fix what they think is the page issue and submit a reconsideration request to Google.

Google will only penalize sites based on the most recent algorithm change and drop previous penalties that have not been addressed by the marketer.

Marketers should always be able to identify exactly what algorithm change is affecting organic page rankings.

If a website is penalized due to a filter like Panda, the filter will periodically re$-$crawl and resolve the problem if bad content has been adjusted since the time of the penalty.
