Digital Current is a marketing firm that has a solid portfolio in search engine optimization. This company offers link building services to websites that need to increase incoming traffic. All hyperlink tags are analyzed to ensure proper HTML formatting. Additionally, all links that lead to malicious sites are removed. After all, Google penalizes sites that provide traffic to external pages that are loaded with viruses and spyware. When it comes to sponsored search, targeted keywords are purchased on top search engine displays for ads. Since there is limited space to describe the ads, effective terms are used to highlight the essence of what is being advertised. Analytic software is also installed on web pages that have been optimized for search engines. The reports contain data about daily traffic and conversion rates of ads. Online stores could also review any sales data and other metrics that are related to profits or losses.
