I started the blog one month ago.. And Yesterday I just added a custom domain to my blog. I found that the traffic is lower than before, why??and the search traffic is dropping... Do I need to configure Anything after I added a custom domain?? Will it affect any SEO after I added a custom domain.. Please explain to me if you know anythings.. Thanks for your help.. Change from http://techpapaa.blogspot.com to http://www.techpapaa.com
Bacause custom domain don't have indexed the article yet. Wait for few more days and do permanent redirect from old URL.
Check your settings in blogger is every thing "on" or everything given "yes" for visibility to search engine. Also check site works fine as par the new domain name. It may take time(undetermined) for Google to crawl your site so that new updates will be reflected and effects traffic. You can also use social media to drive traffic not only depending upon SEs.
Your New domain is Still Fresh So your page haven't been indexed yet by Google. Try to Ping your Blog with new Custom Domain Name
Search Engine have a rule how to give agood ranking for one blog . one blog sometimes has a good ranking, sometimes going down.But, you must manage your blog: 1.post blogpost in some hieger blog if it is possible blog with pr 7 2. post in some directory ,if it is possible twice a day for one blog 3. Ads PTC or ptc,and etc
Be wait, SEO is a process that takes some time to effect. Do you set up A record subdomain name? I mean without www dot?
