Tips and best practices

Place your phrase as close to the beginning of the title as possible, but avoid unnatural keyword stuffing.
Add the phrase to the meta description. It may improve message relevance and increase CTR in search results.
Use the phrase in h1 while maintaining natural language and a clear page structure.
Ensure the phrase appears in the first 100 words to clearly state the content topic from the start.
Distribute the phrase across headings, paragraphs, and lists, but keep a natural style and coherence in your content.
Monitor keyword saturation. Too few appearances may weaken the page topic, while too many may look like keyword stuffing.
Add the phrase to the ALT attribute of images only if the image actually relates to the analyzed topic.
Avoid repeating the phrase in the URL. Short, simple, and readable URLs usually work better.
Check the phrase in anchor texts of internal links, and add links to related subpages if it makes sense for the user.
Avoid linking to external sites with the exact same keyword phrase in anchor text unless necessary.
Enrich your text with related phrases and synonyms, for example from a TF-IDF tool, to strengthen context and on-page optimization.

Missing the phrase in ALT attributes of images important to the page topic.
Using the phrase only in one paragraph, without distributing it naturally in the content.

Case study

An example page scored 60 out of 100. The report showed 5 significant errors: the keyword phrase wasn’t placed at the beginning of the title, was missing from the meta description, and the tool also detected the absence of the phrase in the ALT attribute, subheadings, and main content. After implementing the recommendations, the user improved the title, meta description, h1, image ALTs, and natural phrase saturation in the content. The optimization score increased, and the page was better optimized for the selected phrase. In this example, after resubmitting the URL in Google Search Console, the average position improved from 11th to 5th place.
