Consider combining pages or expanding content to be more complete. Pages under 250 words at scale can lead to significant thin content issues. Think about the words that would also be on the page targeting those terms and make sure you include them. Take for example a page on “A Complete History of New York City” targeting “New York City History”. This page would almost necessarily contain the words “Queens”, “Brooklyn”, etc. If not, it probably won't be complete and Google will expect to see them.
Your chances of ranking will increase even if the query does not include these words - these words are simply deemed necessary based on their existence on other authoritative ranking pages. It may sound simplistic but it works. Focus on comprehensive content that fax number list uses your keywords and terms related to your topic. Don't focus on keyword density, focus on completeness of topic and user experience. Now we know how to optimize content but how do we audit it? It is unfortunately a task of time.
You are going to have to visit each page and read it as if it were your first time there. Think about being a user and what they would expect from following a link to your page and ask yourself if you met their expectations or just yours (and a hint: you are not the person you try to convince). Content auditing is arguably one of the most time-consuming individual steps in any campaign and in some cases, when the site is too large, cannot be fully completed.
