Start with a question worth answering
A newsletter and a social post may both point to the same page, but they serve different audiences and travel through different channels. If you want to compare them, decide what you need to learn before adding tracking to every link. A useful question might be: Which channel brings more visitors to our event page, and which brings more completed registrations? That is more actionable than asking which channel is “best” in general.
Choose one destination and one campaign period for your first comparison. Make sure the destination page works well on a phone, explains the offer clearly, and has an obvious next step. Campaign links can identify where a visit came from; they cannot repair a confusing page. If the page changes substantially during the comparison, note the change so you do not attribute every difference to the channel.
Give each link a consistent label
A campaign link is an ordinary page URL with extra parameters appended to it. Many analytics tools recognize parameters such as utm_source, utm_medium, and utm_campaign. Source identifies the sender or platform, medium describes the channel, and campaign groups links for one effort. For example, a newsletter link might use utm_source=monthly_newsletter, utm_medium=email, and utm_campaign=spring_workshop. A social link to the same page could keep the campaign name but use a platform name as its source and social as its medium.
Write down a short naming convention before publishing. Pick one spelling and capitalization for each value: “email” and “Email” may appear as separate entries in a report. Use simple labels that a colleague will understand later, and avoid placing names, email addresses, or other personal information in URL parameters. If you share the same campaign on several social platforms, give each platform its own source value. This lets you compare them separately without creating a different campaign for every post.
Check links before they go out
Keep a small link log with the destination, tagged URL, channel, publication date, and purpose. A spreadsheet is enough for many small sites. It helps prevent an old link from being copied into a new campaign and makes unusual report labels easier to investigate. Tag links you control in outgoing newsletters and social posts; do not add campaign parameters to ordinary navigation links within your own site, where they can overwrite the visitor’s original attribution.
Open each finished link and confirm that it reaches the intended page. Check that the page still loads if someone removes the parameters, since the underlying URL should remain usable. If your analytics setup offers a way to inspect test visits, verify that the labels arrive as expected. Also check that any URL shortener, email platform, or social scheduling tool preserves the parameters. A quick test before publishing is easier than trying to interpret missing traffic afterward.
Compare useful actions, not just visits
After the campaign, look at visits or sessions by source and medium, then examine the action the page was meant to support. That might be a registration confirmation, a contact form submission, or a download. Compare both the number of visits and the share that completed the action. A channel that sends fewer visits may still help the site’s goal if those visitors are more likely to take the next step.
Keep the comparison fair. A newsletter sent once to a known audience is not the same as a social post that people encounter over several days. Timing, message wording, audience size, and placement can all affect the result. Record these differences alongside the numbers. If you changed the subject line, image, or call to action between channels, treat the outcome as a comparison of those complete messages, not a clean test of email against social media.
Read the gaps as carefully as the totals
Campaign reports are useful signals, not a complete count of everyone who saw or acted on a message. Some visitors may not be measured because of privacy settings, consent choices, blocked scripts, or the way a link was copied and shared. Someone might read a newsletter, return later through a bookmark, and register without the campaign link. A forwarded email can also produce visits that still carry the original email label.
Use the results to make a modest next decision. You might keep the clearest message, improve a page that draws visits but few actions, or repeat a campaign with more consistent timing. Save the link log and a brief note about what you learned. Over several manageable campaigns, consistent labels and careful interpretation will be more useful than a complicated tracking scheme that no one maintains.
