WordPress Research & Evidence-Based Practice 5

Question 1

Which method best helps a WordPress site owner determine whether a newly added sidebar widget improves or harms conversion rates?

Accepted Answer

Running a controlled A/B test with the widget present vs. absent and tracking goal completions

Answer

A controlled A/B test comparing goal completions with and without the widget provides direct, causal evidence of the widget's impact on conversions.

Question 2

When a WordPress researcher uses custom post types to organize evidence sources, which built-in WordPress feature helps establish relationships between posts and their cited evidence?

Accepted Answer

Custom Taxonomies

Answer

Custom Taxonomies allow you to create classification systems (like a 'Source Type' or 'Evidence Level' taxonomy) that establish structured relationships between posts and their referenced evidence.

Question 3

A WordPress site's comment section contains user-generated research feedback. Which approach best extracts actionable insights from this qualitative data?

Accepted Answer

Perform thematic analysis to identify recurring patterns and questions across comments

Answer

Thematic analysis groups qualitative comments into recurring patterns, transforming unstructured user feedback into actionable, evidence-based content improvements.

Question 4

Which WordPress caching behavior can distort research data collected by on-page analytics scripts, and how is this typically mitigated?

Accepted Answer

Full-page caching can serve cached pages without firing analytics scripts; mitigated by excluding analytics scripts from caching or using server-side tracking

Answer

Full-page caching can serve HTML without executing JavaScript analytics tags; this is mitigated by exempting analytics scripts from cache or using server-side event tracking.
