My client asked me if I can speed up Googles algorithm update.

This was funny enough but the peoples rarely understand how seo works. Most take seo services thinking is like ads or something where they can see fast results and when this not happen they complain because they expect different outcome. So is best if you can inform the customers proper first before placing order about how this works

We've all had clients like that. Mine once asked if I could "tell Google to put their website back on page one" after a ranking drop. Sometimes half the job is managing expectations, not just doing SEO.
