In marketing the avenues and channels are endless. In B2B the best approach is a highly targeted one. Discover where your target audience frequents, and meet them there. Shows, forums, events, etc.

I would also suggest investing resources in search marketing, SEM drives traffic and subsequent revenue. And well, if you don’t exist online nowadays, you simply don’t exist. As simple as that.

Lastly, in this Amazon era that we live in reviews are critical. We have become accustomed to checking the reviews of our peers before furthering any interactions with businesses and products. If you are a service, Clutch is extremely well reputable. For software, check into Capterra and G2Crowd.

I am running a website where you can verify any Company detail by its name or by pan card https://www.findyourgst.com/
I want to ask how to promote it. any suggestion

The answer to this question highly depends on what your business is about but here are some general recommendations:

1) List your website on G2Crowd or Capterra. Run campaign targeting your current customers to review your product on those platforms (and offer some kind of incentive like Amazon gift card).

2) Install software like LeadFeeder on your website. It's going to tell you which companies are browsing your website. Use that data to reach out to key people on LinkedIn or add those companies into account based marketing campaign on LinkedIn.

3) Write a very detailed case study or how-to post somehow related to your product. That content piece should be written in a way that "soft sells" the product. A good example is what Ahrefs.com is doing on their blog. Use tools like UpLead to find contact information of your target audience. Or use Nerdy Data (much cheaper but less targeted alternative). Then run a cold emailing campaign to promote the content you wrote. Use HotJar to see if people are actually reading your content and keep following up with useful content which should translate to more sales-y approach as you build trust.

I hope my answer has helped you!
