When you publish content, you want search engines to understand it easily. These are some of the guidelines you should follow before you publish content.
<H1>, <h2> and <h3> tags inform search engines about the topic and sub-topics of your content. You should use them to divide up sections of your content. Thus, H2 is the main topic, and H2, H3 are sub-topics.
I recommend that you include the target keyword in <h1> tag, and it is better if it is part of a longer phrase rather than the exact keyword. Most WordPress themes have set up the page title to be <h1> automatically. So, you should be aware of that and avoid creating two H1’s.
Optimizing a Page for Multiple Keywords
There are times when you need to target multiple keywords on a single page. These are some of the areas where keywords have more value:
2. SEO Title Tag
4. H2, H3, H4
Webmasters debate the optimal number of words per page. I do not have the exact number as this varies per-keyword and per-niche basis. Some tools, such as Surfer SEO can help.
Here, the trick is to get an optimal word count for the pages ranking on page 1 for your keyword and hit the average or a little higher.
Keyword density can be defined as the number of times your key phrase appears in the post of a given length.
Remember that each word of your keyword does count. For instance, if your keyword is “dog training,” and it appears 5 times, but “dog” appears 100 times, and “training” appears 70 times, you can revise Panda Penalty.
You can overcome this by using synonymous. Also, you need to understand how Google’s Natural Language Processing works. For example, if you are writing about “Personal Injury Attorney in Texas,” your content should include claim, compensation, lawyer, court, insurance, accident, negligence, liability, law firm, victim, etc. You can even add a nickname for Texas (The Lone Star State) somewhere in your content. Thus, you should consider increasing such words in your account.
You need to have at least 1 image on your page. Images are important for ranking, but having more images does not always mean your page will rank higher. Remember that having many images on your website will make your site load slowly.
I recommend adding your target keywords in image file names and alt tags. Remember, this will add to the overall keyword density.
