Link building is an important part of any SEO strategy, whether it be the beginning optimization process or as part of your ongoing efforts. Sometimes I am asked “when do I have enough links?” The simple answer to knowing when you have enough links is “you don’t.” You can never have too many links, and you should never stop concentrating on a continued link building strategy. Keep in mind that link building should always be combined with a good technical optimization, on page SEO and off page marketing strategies to achieve not only higher, but lasting rankings. A higher ranking in the SERPs is not much use if you can’t keep it there.
Think of your link building and marketing efforts as a race track that never ends. You have to keep an eye on your competitors and what they are doing in an attempt to stay ahead of the game. You should also keep in mind that your customer’s needs and habits may change over time. You have to be ready to evolve with the changing marketing to meet those needs.
