I recently posted to the gatsby reddit with one of my articles. One of the comments I received was:

"How can I subscribe to new posts? If you don’t have an RSS feed, maybe an article on it would be cool?""

While I was happy that someone was showing interest in my content, it also concerned me that they hadn't found the form for my email newsletter. I must admit that signups had been a little disappointing up to this moment. The UX designer in me thought we could do better! Lets implement a sign-up modal that isn't invasive!

Drawing Attention

We've all visited buzzfeed-type sites that bombard you with sign-up requests that feel invasive. I find that these often appear before I have even looked at the content that I came to see. It is my belief that this damages the user experience and would negatively impact my visitor count if I implemented it. Instead, I wanted to only encourage those that have shown interest in the content to sign up. I also think this leads to a higher quality audience that are more likely to interact with emails you send them.

So, how do we define an engaged user? I decided to opt for article views. If a user has viewed 3 articles within 24 hours I think it is safe to assume they are interested in what I write about.

In order to know which articles you've viewed, I'm going to have to track them but I'd rather not take ownership of any data from users that I don't need so I will keep this information client-side by using localstorage. I have set up a localstorage hook in my project that came in handy when adding reactions to the site and again now. When navigating to an article, I update my "views" localstorage to contain the time at which you looked at the current article (identified by contentID):

Copied!
1.
setViewed({ ...viewed, [contentID]: new Date().getTime() });

Now my code can determine how many articles you have viewed in the last 24 hours with a little help from date-fns:

Copied!
1.
import { differenceInHours } from "date-fns";
2.

3.
function viewedArticlesToday(viewed) {
4.
  const currentDate = new Date();
5.
  let count = 0;
6.
  Object.keys(viewed).forEach((key) => {
7.
    const articleViewedOn = new Date(viewed[key]);
8.
    if (differenceInHours(articleViewedOn, currentDate) <= 24) {
9.
      count++;
10.
    }
11.
  });
12.
  return count;
13.
}

This alone is not enough as repeat visitors who navigate to an article would be prompted to subscribe all the time. That would certainly put them off visiting again! So I also decided to use localstorage to remember when you last saw the modal and whether you had subscribed already. If you have already subscribed, or seen the modal in the last 3 days then it will leave you alone:

Copied!
1.
import React, { useEffect } from "react";
2.
import { differenceInDays } from "date-fns";
3.

4.
useEffect(() => {
5.
  if (
6.
    viewedArticlesToday(viewed) > 2 &&
7.
    !subscribed &&
8.
    differenceInDays(new Date(), new Date(lastSeenDate)) > 2
9.
  ) {
10.
    setModalVisible(true);
11.
  }
12.
}, []);
