Welcome to the Q&A Forum

Canonical tag isn't likely to have the effect you want here. Search engines expect (require) that conicalised pages be essentially identical to each other or they will likely ignore the canonical "suggestion". Identical meaning essentially word for word, except for perhaps word order, like on parameter-sorted product category p[ages. In my experience, EGOL's solution is vastly superior. Create a permanent page for each, then find all the old related blog posts and redirect them to the permanent page to harness whatever authority those pages have for the new one. That way all further authority to the same page year after year, instead of being diffused amongst many weak separate pages. Paul
