Consider the following scenario. There is a single dynamic page that loads different information and meta descriptions based on a query string where there is also a cononical tag so that the query string is not considered as a different page for SEO purposes.
Some content on the page is static like the H1 etc. so that is why there is a cononical tag to avoid duplicate H1s for SEO. Yet there is still dynamic content which we want to provide to a search engine for better search results.
Does this break some search engine rules or negatively effect SEO?
I am thinking there must be some confliction between the fact that the cononical tag says to Google/Bing that there is a single page yet the dynamic content loads different meta information and other content. Surely this would somehow break the different meta descriptions usefullness?
