Analytics CORE Tag – Analytics tag without editing your theme

Analytics CORE is a website analytics service (an external, hosted service — see “External services” below). This plugin adds its measurement tag to your site so you do not have to edit your theme.

Why a plugin instead of pasting the tag into your theme?

• Theme updates cannot delete it. A tag pasted into header.php disappears the next time the theme updates.
• Page-speed plugins cannot break it. Plugins that combine or minify JavaScript can pull an external tag into a bundled file and rewrite its URL. When that happens the tag can stop reporting — silently, with no error anywhere. This plugin outputs the attributes that LiteSpeed Cache, Autoptimize, WP Fastest Cache, Breeze and Cloudflare Rocket Loader look for, so the tag is left alone.
• It only blocks combining, not deferring. Your page speed is not affected: the tag is async and can still be deferred by your cache plugin.
• You can check it. One click fetches your own home page and confirms the tag is really there, and that its URL has not been rewritten.

See your numbers without leaving WordPress (optional).

Paste a read-only API key and the plugin adds a dashboard widget and a toolbar item showing:

• today’s and yesterday’s visitors, and the last seven days as a small chart;
• visitors, views and conversions over the last seven days, and your most viewed pages;
• whether measurement data is still arriving. A tag can stop reporting silently — a theme update, a caching plugin, a change of host. If nothing has arrived for a day, you see it where you already work instead of finding out weeks later.

The key is read-only: it cannot change anything in your Analytics CORE account. Numbers are fetched once an hour in the background, never while one of your pages is loading. Without a key, the plugin asks Analytics CORE for nothing.

Nothing is sent until you say so. Until you enter your Site ID and save, the plugin outputs nothing and contacts nothing.

You need an Analytics CORE account to use this plugin. A free plan is available.

External services

This plugin loads the measurement tag from, and sends measurement data to, Analytics CORE (https://analyticscore.jp), a service operated by Pifto Works.

When data is sent: only after you enter a Site ID and save the settings, and only for visits to the public part of your site.

What is sent: the page URL, the referring URL, screen size, device type, language, and the interactions the service measures (page views, clicks, scroll depth, custom events you define in the service). Your visitors’ IP addresses are not stored by the service; they are used transiently to derive a coarse region.

What is not sent: no data about you as the site owner — no administrator e-mail address, no user accounts, no post content.

Reading your numbers back (only if you add an API key): if you paste a read-only API key under Settings, the plugin asks https://analyticscore.jp/api/v1/site-summary once an hour, and when you press “Refresh now”, for the summary shown on your dashboard. The request contains your Site ID and your API key and nothing else. Remove the key and the requests stop.
