Besides the main keyword, also use long-tail keywords in the page title to improve relevance and detail. Long-tail keywords face less competition, so it is easier to reach the right searchers.

Optimize the meta description

Check Meta tags for missing, duplicate or too-short ones. Optimising the Meta Description helps Google rate your article well. It also lets searchers picture what your page is about, so they can decide whether to click your result on the SERPs.

Check the H1 tag

There should be only one the H1 tag on a page. If you find more than one H1, change the extras to H2, H3 and so on. Make sure the H1 contains the main keyword article.

Optimize friendly URLs

Note that you need to include the keyword in the URL so Google understands what your page is about and recognizes it more easily.

A short URL is also easier to remember and share. It helps the page load faster and makes it friendlier to use.

Use the keyword in the first 150 words

Placing the keyword in the first 150 words of an article helps search engines quickly understand the main content and makes search results more accurate. It also helps Google show your article among the top results.

Use keywords in Heading tags

Using keywords in heading tags helps search engines understand the structure of your page and the main topic of each section. Besides the main keyword in headings, also use related keywords in the lower headings to avoid over-optimizing and keyword spam.

Optimize images

Optimizing images on your site includes reducing file size, using file names and the ALT tag with keywords, so search engines can understand what the image shows.

Use synonym keywords

Using synonyms and variations of the main keyword makes your content richer and avoids repeating the main keyword too often. But don't use too many synonyms or variations in one article, because this can make the text hard to read and unnatural.

Use external links

Linking to reputable, high-quality websites can help your site rank higher in search results. But don't link to too many external links sites in one article, and only choose sites that are relevant to your content.
