Growing your messenger subscriber list and driving them to pages on your website is one of the most effective ways to get more traffic. These messages get a 90%+ open rate and a 50%+ click-through rate which almost guarantees they will see your next blog post or resource you created. Messaging apps are surpassing social networks and are not going anywhere anytime soon. I recommend you get started soon because these amazing engagement rates will not last long.
A Blog: If you are using blog and you are relying on Adsense, then you can buy traffic. I suggest it only if you are in a very bad state/ initialization phase of blog. Do not go for a huge number of traffic for the first time, increase the number of visitors in time (to avoid suspicion from search engines). You must also consider re-targeting these readers. But remember you can’t afford to buy traffic all the time, one of these days Google is going to find you, so alongside adopt SEO, content marketing practices also. In order o buy traffic, I would suggest fiverr. look for reputed seller/ reviews. Adopt practices suggested here.
Building an email list for email marketing can take a long time, so it’s important to start building it out on day one. With email marketing, you’ll be able to keep driving website traffic to your store as long as your customers stay subscribed. With social media sites continuously limiting your reach, email marketing is one of the only marketing channels you can have complete control over. You can build an email list by adding Email Popup Box, which adds opt-in forms to your website. You can also use Spin-a-Sale to collect emails upon exit intent, or try Product Notify which emails customers if there’s a product price change.
Buying website traffic shouldn't be a replacement for SEO and other conventional methods of online marketing, but it can certainly give you that edge you need in the highly competitive online market. You can improve your Alexa ranking, time on site and lower bounce rate, but most importantly - it will drive potential clients and bring your website in front of your target audience long before you will see the first results of your conventional marketing strategies.
