Yes, you should seriously consider investing in SEO even if you are engaging in PPC advertising services. As we all know the PPC advertising is very costly in comparison to SEO services and does not create sustainable results. PPC provides you instant results but it’s not effective if you are not on a good budget. SEO marketing is also a preferred marketing part because it delivers you long term results. People also believe more in organic SEO results rather than paid ad results, and that is essential for creating a unique brand identity.
