In Northeast Florida my experience has been that it is slower in January/February as far as showing traffic/potential tenants. 

If you're in the right location, you're going to continue to get traffic.

Agents drive more traffic and do more due diligence for you.

Well, in 2018 76% of all online traffic was online video. 2019 is projected to 82% of all consumer internet traffic will be video.

@Leah Thibeault there are tons of high traffic posts on this subject!

Ingress/egress is considered, other tenant mix to draw foot traffic, exclusive use clauses, pylon signage, visibility, parking ratios, etc all matter. 

Most traffic will be on Zillow or MLS.I would try Zillow first, if not enough interest I would do a flat fee MLS listing.FB groups national and local for STR's would be another free place to advertise.

The listing and the photos looks great and you are posting on all the top sites.I would recommend reevaluating the price to see if a price adjustment will drive traffic as well as consider posting to a site like Facebook Marketplace.I know that our market in San Diego is different than where you are located, but we are seeing it takes approximately 23 days for a property to be leased. 

However, how do we know how much traffic does the blog have, and what's the best way to showcase this article?

On the corner of 2 high-traffic roads.
