How to fix this issue
It is recommended to generate unique meta descriptions using keywords a specific page is optimized for, as well as a call for an action.
The solution is creating unique meta descriptions for this page.
Some key guidelines for producing good meta descriptions are listed below:
- Write appealing meta descriptions that would efficiently advertise web pages and would determine users to choose your site as opposed to others.
- Use complete sentences and make them highly readable and natural-sounding.
- The text of the meta description should focus on the particular page rather than on the entire site.
- Anticipate user expectations in terms of content and try to meet these expectations by making appropriate references to this content in the meta description.
- Use carefully selected keywords in your meta description – in case these match the user query, they will be displayed in bold within the SERP snippet.
- Avoid stuffing too many keywords in the meta description.
- Ensure each meta description is unique.
- Don’t exceed the length limit of 160 characters, otherwise, your text might get truncated.
- Truncation can also be triggered by the use of non-alphanumeric characters, such as double quotes – avoid these, since search engines might delete any text following them.
