10 days ago I was wondering if I should merge the 3 Perl Maven sites. The recommendation by everyone was to merge the perl5maven.com site into the perlmaven.com site. As I had the same feeling too, I did it on May 1, just 8 days ago.
It went quite smooth, but there was a price!
The number of visitors went down from 2,200/day to 1,500 on May 6. It slightly recovered to 1,800 on May 7, but it does not look very good today either.
I am not sure what is the exact source of this change, but let's look at a few possibilities and ways to fix them.
The incoming links are still pointing to the old domain. I used the Webmaster tools of Google to locate the incoming links. Updated where it came from my other sites and sent a few e-mails asking people to replace the link. This will take time till Google reindexes those pages and notices the change in URL.
Obviously (?), the old domain uses 301 redirect to let every visitor, both human, and bot, know that the pages moved. If someone clicks on an incoming link still going to the old address, those people will be redirected to the new address, but I think it is better to eliminate that step.
As Google is the biggest source of visitors, having a high Google Page Rank is probably important. The old domain had Page Rank 4, the new one currently has 3. In time, I am sure the new domain will get higher, especially as Google notices the updated incoming links and as more sites will link to the new address.
One thing is unclear though. If Google still shows the links to the old site in the search results, why would it use the Page Rank of the new site?
In the Webmaster tools of Google, I told it the old site was moved to the new address. I guess it will take some time till Google starts to take this information in account.
Another thing I noticed is that I lost all the social counters indicating that this site is good for some people. I have links to Reddit, Google+ and Twitter on each page, but as the counters on those button are connected to the underlying URLs, they all became 0 when I moved the pages. Same with all the comments made using Disqus.
Luckily, Disqus has a tool to allow easy migration. As I set up 301 redirect on the old site, I could just tell Disqus to crawl all the pages that had comments on them, and associate the comments with their new home. The comments have already moved.
In the Twitter button I can configure two URLs: data-url is the URL that will be included in the tweet if someone clicks on the button. data-counturl is the URL that 'counts' the tweets. I configured my system so for every page, that was created before May 1 2013, I set the data-counturl to be the old URL on perl5maven.com. With this fix I can see the nice numbers of Twitter.
I have not found anything similar for Reddit.
For all the articles that were published before the merge-date, I set the Reddit link to point to the old site. It would be probably better to point only the pages that actually have been posted to Reddit, but that requires more work.
I have not seen any place where Google mentions what to do with the Google+ count, but after a few days I noticed that the Perl Tutorial page, which is the most visited page on my site had suddenly jumped to 76. I don't think that 76 people have +1-ed the page on the new site in the past few days, so apparently Google can handle such moves automatically. Checking the other pages, some of them still show 0 bot others already have a larger number. I assume this happens as Google slowly notices that the old pages have moved. Nice.
I don't have Facebook buttons and counters on my site but this page, where I got the Twitter solution from, has some explanation for Facebook as well.
There is no real conclusion yet. I have to see how does this work out in the long run. How long will it take for the number of visitors to recover? Will people link to the new site? Will they help by sharing the useful articles on Google+ or on Twitter?Published on 2013-05-08 by Gabor Szabo blog comments powered by Disqus
