Regardless of whether or not it's useful, it's substantially plagiarized from another source. You don't have an inline citation or visual indication that many of the figures are copied from another article on the topic. The same goes for copying paragraphs with extremely minimal modifications.
Slightly changing sentence structure is not paraphrasing or stating in your own words. Pointing a reader to an article for further reading is not the same as a citation.
To put it bluntly, your arrangement of the material, substantial paragraphs, and a significant number of your figures/graphics are copied from elsewhere without citation.
I cite them at the end. The idea was to summarize all the articles into one. I will add a note to the self-attention section - that is the one that I used from Jay's blog. My idea was to summarize all the content from these posts and videos that are referenced at the end into one blog post. I hope it was useful for some people
That's not good enough. Citations must be in the text, so that nobody mistakes their work for yours. This can be informally like 'Jay describes", or 'Sally's article says', and then your words, or a quote 'in quotation marks' with a link to their work.
Note that if the other blog post is not licensed under a license that allows you to do so (such as Creative Commons Share-Alike), you are simply not permitted to copy images or text without explicit permission from the authors. It's not enough to state that it was taken from another post.
Of course, you are allowed to cite excerpts, but then the text should be clearly marked up as a citation.
The right thing to do is to either bring down the blog post, replacing it with references to the used articles, or quickly transform (pun intended) the paragraphs and graphics into your own. As it stands, it’s plagiarism.
