Make sure your article title is a heading, so screen readers can jump to it quickly. Try and mark the article text with the main ARIA landmark. Put social media sharing buttons, related posts, and other clutter that comes with each article, into the complementary ARIA landmark, so screen reader users can quickly skip over it. Doing these things will mean that even a first time visitor to your blog can skip directly to the article and start reading, with only a couple keypresses. If you're using wordpress with a decent modern theme, most of this stuff might have been done for you already.
