Hello, We run two sites with the same product, product descriptions and url structure. Essentially, the two sites are the same except for domain name and minor differences on the home pages. We've run this way for quite a few years. Both sites have a domain authority of 48 and there are not a large number of duplicate incoming links. I understand the "book" to say we should combine the sites with 301's to the similar pages. I am concerned about doing this because "site 2" still does about 20% of our business. We have been losing organic traffic for a number of years. I think this mainly has to do with a more competitive environment. However, where google used to serve both our sites for a search term it now will only show one. How much organic benefit should we see if we combine. Will it be significant enough to merge the two sites. Understandably, I realize the future can't be predicted but I would like to know if anyone has had a similar experience or opinion Thanks
