On-Page SEO Checklist: 14 Effective Strategies

Here is the complete on-page SEO checklist for you to optimize your web pages.

1. Keyword Research and Optimization

Step 1: Identify Your Target Keywords

You first need to understand the keywords that your audience is likely to search for before you start creating and editing your content. You can use any tool for keyword researching to look for the relevant words or terms that are similar to your content, and have a higher reach. 

Also, remember that the keywords, which are long phrases, also called long-tail keywords, have a higher reach and are easier to rank and attract traffic to your site.

You can easily get a few of the long-tail keywords for your site simply from Google Searches. Simply, just type any keyword in the Google search bar, but don’t hit enter from your keyboard or click on the Google Search button. Instead, check out the keywords that Google shows you, especially those that appear first as suggestions for your site.

Step 2: Use Keywords Naturally

Now is the time to use these researched keywords in your content. You can add these keywords in your blog titles, headings, and even the body section.

Also, you need to ensure that you do not overuse the keywords; the keywords must be inserted in between the text naturally, not by forcing them to increase the SEO score. Since overusing the keywords or simply keyword stuffing can degrade your site’s ranking.

For example, let’s say you want to rank for How to Add Pages In WordPress. To integrate the relevant keywords in your content, you need to first use the exact keyword in a few places in your content. You can also take the help of some synonyms such as “How to Insert Pages in WordPress”, “Adding Pages in WordPress”, “How to Setup Pages in WordPress”, etc.

Once you are done with this, you can then use the LSI (latent semantic indexing) keywords. These are the keywords that you can use along with your main keyword but are relevant to the main or the focus keyword. In this case, you can use “WordPress”, “Adding page”, “Pages in WordPress”, etc.

Avoid Keyword Stuffing

Step 3: Focus on Search Intent

You need to check your users’ demands. Do they want to have a detailed guide, quick answers in the form of FAQs, or simply some step-by-step instructions? This means that your content must be inclined towards the intent behind using the specific keywords. 

This also involves understanding the search intensity of your users. This alignment between content and intent is a very crucial signal for the search engines behind ranking your site.

2. Content Quality and Relevance

Step 1: Write for Your Audience

You need to make sure that the content you are writing solves any specific problem of the users. Your site visitors click on your site just to find a specific answer to their query, and your content must be inclined to provide their answers.

Always keep your writing simple and easy so that even the most complex topic seems easier to the user.

Step 2: Structure Your Content

You can divide your entire content into different logical sections with the help of headings and subheadings using the H2 and H3 tags.

This approach improves the readability of your content and also allows search engines to understand the hierarchy of the information in your content. You can even use bullet or numbered lists to make certain sections of your content clearer to understand.

Always ensure that the title you provide perfectly describes the entire content of that page and that it also includes the primary keyword you set.

Your title must also be 50-60 characters so that it becomes fully visible in the search results. For instance, this blog discusses the importance of WordPress tags in SEO building. Here, look over the title of the blog.

Step 2: Organize Content with H2s and H3s

Subheadings such as H2, H3, etc., help break your content into sections. They help guide your users through your article and help search engines understand what topics are covered. Make sure your subheadings are descriptive and include secondary keywords wherever relevant.
