There are two options to getting an internet project off the ground. In the first case, you invest the majority of your funds into SEO and will soon start to see a sustainable increase in target visitors, coming from organic search. In the second case, the majority of funds are allocated to online advertising, which leads to a spike in site visits, while you campaign is active. The most effective online ads are contextual links, which are displayed to users in search engines when they type in a particular request.
Both approaches can also be combined. However, it needs to be understood that the SEO budget should be fairly sizeable, in so far as this approach requires the input of a large number of specialists.
