Google Posts are short updates — up to 1,500 characters with an optional image and call-to-action button — that appear directly on your Google Business Profile in search results and Google Maps. For clinical research sites, regular posting signals to Google that the profile is actively managed, provides fresh content for patients reviewing your listing, and gives you additional opportunities to include the condition-specific keywords that support local search rankings.
Post Types That Work for Research Sites
The most effective post types for clinical research sites fall into three categories. The first is trial enrollment announcements: a brief description of a currently enrolling study, the condition being studied, key eligibility criteria (age range, condition status), and a call-to-action button linked to your trial landing page or pre-screening form. These posts serve double duty as both a ranking signal and a direct patient conversion path from the GBP listing itself.
The second effective type is patient education content: a brief, useful fact or explanation related to a condition your site studies. “Did you know? Type 2 diabetes clinical trials have led to every FDA-approved medication currently on the market” — this type of post builds credibility, adds relevant keyword context to your profile, and gives patients a reason to read your full profile rather than immediately moving to the next result. The third type is operational updates: new staff, certifications, accreditations, or participation in research advocacy events. These build the trust and authority signals that support prominence in local rankings.
Post Frequency and the Activity Signal
Standard Google Posts expire after seven days. This means a site that posts once per month has an active, visible post for seven days and an empty post section for the remaining 23. Google’s local algorithm uses profile activity as a relevance and quality signal — profiles that are consistently updated perform better in local rankings than identical profiles that are updated sporadically. Post at minimum once per week. If your site has multiple active trials, post about each in rotation to maintain condition-specific keyword coverage across your post history.
Offer posts do not expire — they remain active until you set an end date. If your site offers compensation for trial participation, create an ongoing Offer post with the compensation range and a link to a currently enrolling trial. This post type displays differently in search results and can stand out visually against competitor listings that use only standard posts.
Images, CTAs, and Tracking Post Performance
Posts with images receive significantly more views than text-only posts. Use high-quality images of your site exterior, staff, or condition-relevant medical imagery — not stock photo collages. Google compresses images displayed in posts, so start with images of at least 1200 x 900 pixels to maintain quality after compression. Each post should include one of the available CTA buttons: “Learn More,” “Sign Up,” “Call Now,” or “Get Offer” depending on the post type. Link “Learn More” buttons to the specific trial page or blog post you are promoting, not to your homepage.
Monitor post performance in the GBP Insights section under Posts. Google shows how many views each post received and how many button clicks it generated. Use this data to identify which post types, topics, and images generate the highest engagement and replicate those patterns in future posts. A research site that publishes 52 posts per year with monthly performance reviews will consistently outperform one that posts irregularly with no performance analysis.
Consistent GBP posting is one of the lowest-cost, highest-consistency local SEO activities available. It requires 15 to 20 minutes per week, no technical expertise, and no budget beyond the staff time — and it is one of the activities that most directly differentiates actively managed profiles from the static, unclaimed profiles that most research site competitors have.
