Semrush is the well-known SEO and competitive research platform; the Social Media Toolkit is one of many add-on toolkits inside the broader Semrush product. It is rarely bought as a standalone scheduler — most teams adopt it because they already pay Semrush for SEO. BulkPublish is a focused multi-platform publisher with flat-rate pricing across 11 networks. Different jobs, different value proposition.
Here is how they compare in 2026.
Pricing Comparison
| Plan | Semrush | BulkPublish |
|---|---|---|
| Free | Limited free Semrush account | Free forever — 10 channels (1 per platform, all except X), 3 posts/day |
| Social Toolkit Base | $20/mo — 5 profiles, 50 posts/mo, 30 AI generations/mo | — |
| Pro (BulkPublish) | — | $13.99/mo ($11.89/mo annual) — 22 channels, 3 orgs |
| Semrush Pro plan | $139.95/mo (often required for full Semrush context) | — |
| Business (BulkPublish) | — | $39.99/mo ($33.99/mo annual) — 55 channels, 10 orgs |
| Semrush Guru plan | $249.95/mo | — |
| Semrush Business plan | $499.95/mo | — |
The Social Media Toolkit at $20/mo looks competitive on paper, but the practical comparison is different. Semrush’s Social Toolkit is generally adopted by teams already paying $139.95–$499.95/mo for the core Semrush platform — the social piece is an add-on inside a bigger SEO bill, not a standalone $20 product.
BulkPublish Pro at $13.99/mo is a complete, standalone publishing tool with no underlying SEO platform required.

Channels Supported
Semrush Social Toolkit supports the major networks for posting and tracking — Facebook, Instagram, LinkedIn, X, Pinterest, and others — with depth varying by feature (Social Tracker covers more sources than Social Inbox).
BulkPublish covers 11 platforms with uniform support: Instagram, Facebook, X, LinkedIn, TikTok, YouTube, Pinterest, Threads, Bluesky, Mastodon, and Google Business Profile.
Where Semrush Wins
Semrush’s value is the integration, not the scheduling. If you already live in Semrush, the Social Toolkit fits naturally.
- Integrated with SEO and competitive research — Social posting decisions can be informed by keyword data, competitor performance, and content opportunities surfaced elsewhere in Semrush. For SEO-led teams, that integration shortens the workflow between “what should we publish?” and “publish it.”
- Social Tracker — Track competitor social profiles alongside their SEO presence. Useful for benchmarking organic and social together.
- Cross-channel analytics — Analytics that connect social performance to overall content and search performance within the Semrush dashboard.
- AI content with brand context — Semrush’s AI can use your brand voice and competitive context (already in the platform) when generating social copy.
- One vendor for SEO + social — Procurement simplicity for teams already on Semrush. One contract, one billing relationship, one login.
- Bundled with broader Semrush ecosystem — Position Tracking, Site Audit, Backlink Audit, Topic Research, and many other tools.
If you already pay for Semrush and need basic social scheduling alongside SEO research, the Social Toolkit add-on is the logical choice. You will not get a better scheduler for $20/mo when you are also getting integration with the rest of Semrush.
Where BulkPublish Wins
For teams that do not already live in Semrush, the math changes completely.
- Standalone product, standalone price — BulkPublish Pro at $13.99/mo is a complete tool. Semrush Social Toolkit at $20/mo realistically requires a $139.95+/mo Semrush plan to make sense — total real cost is north of $160/mo.
- Massively higher publishing capacity — BulkPublish Pro: 30 posts/day (~900/mo). Semrush Social Toolkit Base: 50/mo. That is 18x the publishing volume per month.
- More platforms, equally supported — BulkPublish covers 11 networks including Bluesky, Mastodon, Threads, and Google Business Profile.
- Real free plan — BulkPublish free allows ~90 posts/mo across 10 platforms with no Semrush account required.
- Multiple organizations — BulkPublish Pro includes 3 workspaces for managing multiple brands. Semrush Social Toolkit’s profile limits are tighter.
- API on every plan — Full REST API on free, Pro, and Business. Semrush’s API is gated to the $499.95/mo Business plan.
- No SEO platform overhead — If SEO research is not your job, you do not need (and should not pay for) the Semrush platform underneath.
The Bottom Line
Semrush Social Toolkit is best understood as “the social scheduler you use because you already pay for Semrush.” It is not really a standalone publishing product, and the $20/mo price is misleading without the $139.95+/mo Semrush context. For SEO-led teams already invested in Semrush, the Social Toolkit is a sensible add-on that integrates with the rest of the platform.
For everyone else — creators, agencies, and small teams who just need to publish across platforms — paying for the Semrush platform to get the social piece is upside-down.
BulkPublish Pro at $13.99/mo flat covers 11 platforms with 22 channels, 30 posts/day, 3 organizations, post recycling, and a full API. No SEO platform required, no $139.95/mo prerequisite. If your job is publishing rather than SEO research, BulkPublish is the focused tool at the focused price.
