What happened to my website serp ranking

Hello,

Thank you for contacting Rank Math support, and sorry for any inconvenience that might have been caused due to that.

Please note that ranking on Google depends on so much more than just your on-page optimization. You could have the perfect article and still struggle to break the top 10 in SERPs. Here are some of the factors Google considers when ranking you:

1. Your website’s authority
2. Your content’s quality and how better it is than the other article currently ranking.
3. How competitive the keyword is.
4. How many backlinks you have and if they are better than what the other guys ranking for that keyword have.
5. Your website’s crawlability.
6. Frequency of new content and content updates.
7. So much more that there is a dedicated blog post on it by Brian Dean 🙂

As for the issues with your snippet, could you please share your website URL or the affected URL so we can have a closer look at the metas?

Please note that it is a pretty common thing with Google these days. It happens with 70% of the results and we even have a KB dedicated to this problem and a few solutions we recommend:

Please check the KB and you will understand the reasons Google does this.

Google has made some changes to their algorithm which automatically changes the titles, discarding the one you have set in your SEO title meta tag. This happens regardless of the SEO plugin you are using. We have covered this Google update here:

Looking forward to helping you.
