On our corporate website we have a blog where we publish articles which are directly related to our company (house heating systems and gas cylinders) and some articles which are completely irrelevant to our core business, but which might be of interest to our potential clients. In other words, the idea was to attract potential customers to our corporate blog through quality content about house building and inside of those articles include information about our own products and services.
Recently I've been told that it is not a good idea to include these type of articles (blog posts which are not directly related to our core business), because Google might be confused as to what our core business is about. I was advised to remove these blog posts from our corporate blog. By removing I mean completely removing pages and setting a 410 status to tell Google that it is not a 404 error but that these pages were intentionally removed.
Our website is available in Latvian and Russian language. [link removed by moderator]
I would like to hear some independent advice from community members on this topic.
Thank you very much in advance.
