How to mobilize your supporters for collective action
What is grassroots mobilization, why is it a powerful strategy to get the results you want, and types of actions you can rally your supporters to participate in to win.In this article you will learn:
Siddhu Pachipala created his first petition as a high school senior to stop Texas representatives from removing minority history from the K-12 school curriculum. In an interview with Change.org, Siddhu said that his nearly 180,000 supporters made up a “coalition that’s wanting to change something fundamental about the education system.”
His friends said they’ve never seen someone their age address a legislative issue, and realized they do have power to make a difference. And it wasn’t just young students supporting the cause — administrators, teachers, and parents who shared concerns about the issue also joined the movement.
The platform that Siddhu’s petition created was a way of “democratizing the idea of what an activist is” so anyone, regardless of background, could get involved and push for change. Siddhu emphasized the importance of having that coalition fighting for a common cause and “getting those people together because you can’t do it without that group.”

What is grassroots mobilization and why is it important?
Grassroots mobilization is the process of bringing everyday people together at the community level to advocate for progress and policy. Instead of relying on top-down leadership, grassroots efforts thrive on shared responsibility and energy where everyone plays a part.
The terms mobilizing and organizing are often used interchangeably, but they’re slightly different. Mobilizing is about inspiring people to participate in collective action—signing a petition, showing up to a protest, or voting in an election. Organizing goes deeper. It’s about building long-term structures and relationships that keep a movement going beyond a single moment.

Examples of successful mobilizing from grassroots movements
Mobilizing supporters to engage in collective action is essential to achieve your goals, and has been the driving force of successful movements throughout history. The following are just a couple examples of the impact of mobilization in grassroots campaigns.
Georgia voter mobilization (2020–2021)
A grassroots movement achieved its goals to flip Georgia from red to blue in the 2020 presidential election and win two critical U.S. Senate runoff races in January 2021.
The grassroots organizations involved included Fair Fight Action, New Georgia Project, Black Voters Matter, and Georgia Alliance for Progress. Some of their mobilization efforts and resulting achievements include:
Massive voter registration drives and social media campaigns targeting community members who were first-time voters, young voters, and minority voters resulted in 800,000 new voters registered in Georgia between 2018 and 2020.
Supporters contributing to door-knocking, phone and text banking, and local partnerships with churches and community centers delivered their message to voters centered around community needs.
National and local volunteers kept the outreach going nonstop through the holidays, helping to turn out a historic 4.5+ million people who voted in the Senate runoff election.
Ultimately, these combined efforts resulted in President Biden winning Georgia in 2020, and the election of Senators Jon Ossoff and Raphael Warnock in 2021.
2023 SAG-AFTRA strike
The 2023 SAG-AFTRA strike over contract negotiation conflicts with the Alliance of Motion Picture and Television Producers (AMPTP) is another grassroots mobilization triumph within the entertainment industry.
SAG-AFTRA's leadership galvanized approximately 160,000 members to participate in the strike, demanding fair compensation, residuals from streaming platforms, and protections against the unauthorized use of artificial intelligence (AI) in reproducing actors' likenesses.
Members organized and engaged in widespread picketing at major studios and production sites across key locations like Los Angeles and New York City. The union and its members used traditional and social media channels to communicate their goals, report developments, and rally support.
Their efforts led to securing wage increases, streaming residuals, and AI protections for SAG-AFTRA members.
Steps for successfully mobilizing supporters
Once you’ve built a strong foundation for your campaign, then you can start mobilizing. The initial groundwork you need to do before getting to work on specific actions include:
Defining your issue
Setting your goals
Identifying your decision maker
Creating your petition or other campaign materials
Follow these steps to plan and inspire collective action from your supporters to win the change you’re seeking.
Communicate a strong, inspiring message
Convey the urgency or importance of your issue in your petition and in any other outreach to your audience. Include examples and personal stories of how the issue is directly impacting your community. To resonate with potential supporters, you need to explain how the issue concerns their lives, because as Siddhu points out, “if people don’t feel affected by the issue, they may not sign onto it.”
Your message to your supporters should highlight how their participation can help get the result everyone wants. Explain that working together to raise awareness about the issue and putting pressure on the decision makers to address it will make progress. There’s power in numbers. This will inspire and motivate them to take action.
Use petition updates to organize and encourage actions
The petition updates tool on Change.org is a free resource you can use to post messages on your petition that will automatically email to everyone who’s signed it. This is an effective and convenient way to share how supporters can participate and provide them with instructions and resources.
By using the petition updates tool, one successful petition starter prompted his supporters to contact their state representatives and donate to making campaign videos, resulting in getting an important law passed.
Facilitate direct actions for supporters to take
Ready, set, action. Here are some proven actions you and your fellow advocates can take to reach your goals, plus tips to set your supporters up for success.
→ Contact the decision maker directly
Direct outreach to the leaders or officials with the authority to respond to your petition is crucial for getting results.
In a Change.org survey, petition starters said that in addition to signing, when supporters personally contacted the decision maker, it made a noticeable difference in getting a response.
In a different survey, decision makers said the best ways constituents can contact them are by:
Emailing (32.69%)
Setting up an in-person meeting (23.08%)
Calling their office (19.23%)
Speaking at a town hall style meeting (13.46%)
Tagging them on social media (11.54%).
Both petition starters and decision makers point to the number of signatures a petition has and the amount of local community support it has as the top drivers of getting decision makers’ attention. So when asking your supporters to contact decision makers, be sure to provide this information and instruct them to share it.
→ Tip: You can find out how many of your supporters are local in your Change.org petition dashboard.
To help mobilize your supporters to contact decision makers, provide them with the key points and call to action they should include in their message. For example, Siddhu created a helpful resource for his supporters that included everything they needed to put pressure on Texas state representatives in his Action Center, including:
A link to find the representative of their district
How to email their representative
An email template to their representative
How to call their representative
A script they could use when calling their representative
Sample Instagram and Snapchat posts, including a custom image, they could share
→ Share the petition on social media
Asking supporters to share the petition across social media platforms expands its reach and keeps the pressure on decision makers. This was another top tactic identified by petition starters surveyed to gain momentum and get the attention of decision makers.
Be sure to provide your supporters with all the resources they need to successfully promote the campaign on social media, including:
A custom petition link, which you can create on Change.org
Custom images or videos you can create using tools like Canva
Hashtags specific to your campaign
Sample captions or key points to include
→ Leave helpful comments on the petition
Another valuable Change.org feature is the ability for signers to leave public comments. These are also one of the best ways both petition starters and decision makers cited to encourage a response. Supporters who leave written or video comments add depth and relevance to the campaign, making it harder for decision makers to ignore.
Decision makers reported that the most influential types of supporter testimonials are ones that include:
Real, personal impact: Authentic stories from people directly affected by the issue — especially if the person lives in their district or community.
Supporting facts and information: Many decision makers emphasized they want testimonials backed by solid facts, relevant laws, or credible data
Respectful and thoughtful messages: Decision makers value testimonials that are respectful, well-reasoned, and avoid partisanship, exaggeration, or conspiracy theories. Testimonials that feel genuine (not templated or AI-generated) also stand out.
Fresh perspectives: Some decision makers noted that stories revealing aspects of the issue they hadn’t previously considered can help shift their thinking — even more than general statements of concern.
Example of successfully mobilizing petition signers
This petition calling for urgent wildfire debris cleanup shows successful mobilization efforts in action. The fight is ongoing, but the petition has nearly 10,000 signatures and has encouraged many supporters to take action.
This petition demands that Governor Gavin Newsom and Los Angeles County officials take immediate action to address toxic wildfire debris polluting the coastline following the Palisades Fire. The organizer supported their case and provided signers with helpful information by sharing:
Scientific details about the types of pollutants (heavy metals, dioxins, asbestos) and their health/ecological risks.
Explanations of environmental processes, like how storm drains and tides carry debris back into the ocean.
Specific, actionable demands for containment, cleanup, and transparent testing.
Framing of the issue's urgency with references to upcoming storms and ongoing contamination risks.
The campaigner used petition updates to organize the following collective actions:
A protest with instructions that attracted a big turnout
Calling elected officials to demand immediate action
A Zoom meeting for supporters to attend to hear campaign progress, developments, and next steps
An in-person and virtual “March to the Sea” to raise visibility for their demands. Supporters were also encouraged to bring signs or instruments, spread the word on social media, volunteer to help with the event, and, for those unable to attend in person, take remote actions like contacting local representatives, writing letters to Congress, and sharing the petition online.
Mobilize your supporters, move decision makers
Petitions work best when they’re a tool for action, not just a collection of signatures. Use your petition to organize your supporters, keep them informed, and give them clear steps to influence decision makers directly.
When you combine a strong petition with collective action — like contacting officials, sharing your campaign, and showing up for events — you increase your chances of winning real change. Ordinary citizens can make a difference.
