I was posting articles with 1 link per page but i have noticed that companies similar to mine, are adding up to 100 links per 1000-1500 words article. Going by the google recommendations, there is no limit on numbers of links per page.
I agree that putting 100's of links on a page not only looks like spam, it is spam. I'd like to add that the only reason for posting articles with links is if the articles are quality and have viewer volume. If you are writing articles that nobody will read you are wasting your time. For cleaning companies like my window cleaning business and your carpet cleaning it is difficult if not impossible to create articles that have relevance and are newsworthy. For Top Notch Windows we don't find the cost of producing them to have a good return. I wonder what others are seeing?
