Hubspot found that their articles up to 2500 words drive the most traffic. Similarly, posts with more than 2500 words generated more social shares and links.

This way, your investment will more than pay for itself because your content will be serving your business goals years down the line. Put people first. The thing about search engines and how they rank content? It’s unpredictable. But one thing will remain constant. The job of a search engine is to connect users with the most relevant and useful information. If your content serves that purpose, you don’t have to fear algorithm changes.
Look at the different search engines (sources) that drive traffic to your site to determine where you want to invest your resources. For example, if you're getting an overwhelming amount of visitors and revenue from a particular search engine, that's an obvious source of profitable traffic and an area in which you might want to make further investment; but you might also find another search engine that delivers only a few visitors, but ones who represent a very high Per Visit Value. In this latter case, you might want to increase your spend in that area to drive more of those high-value visitors to your site.
