Yes! If you’re not familiar with HTTPS, it is essentially a more secure form of HTTP. Look up at the URL of this page. See the “https” at the beginning, and the word “Secure” to the left of it? Google looks on pages like these favorably. Not only does it index HTTPS pages first, but it also recognizes HTTPS as a ranking signal. HTTPS is also faster than HTTP, which can affect the click-through rate. So yes, changing to HTTPS should positively impact your rankings!
