Tumblr and WordPress: a crawler’s difference
After the move I activated the Google XML sitemap plugin which submits the blog’s sitemap automatically to different search engines.
Look at the Google Webmaster statistics! From 0 pages crawled per day to about 750 per day… And crawling is good. You want your pages to be indexed by the search engine crawlers, as that generates search traffic.
…Almost on the spot, the traffic coming in from Google searches picked up….
Conclusion: WordPress rocks. If you are serious about your blog, and want to make it attractive to search engines, don’t put your blog on Tumblr…
