In my opinion, blogging is one of the most valuable marketing tools available to businesses.
Hubspot's previous analysis of 1,500 Hubspot customers (small businesses) found that companies with a blog attracted 55 percent more visitors to their websites than those that did not. The ones that blogged also had 434 percent more pages indexed in search engines.
In addition, according to their Marketing Benchmarks from 7,000 HubSpot's customers, businesses with websites greater than 400 pages, get 6x more leads than those with 51-100 pages.
Although their information is somewhat dated, I'd surmise that the numbers could only be greater at this point.
Your blog will only be as effective as its functionality, appearance and quality of content. Move in the right direction using these content marketing tips.
