Yahoo has been threatening to shut down Yahoo Site Explorer for quite awhile now, and later this year it will officially be shut down. What does this mean for Search Engine Optimization? Yahoo Site Explorer, has been one my preferred methods for checking back links because it gives far more detail than Google. Yahoo claims that they will be transferring the information to Bing Webmaster Tools, but it seems unlikely that we will be given the same vast amount of information. Working in SEO means constantly adjusting to search engine changes and new regulations. At Emboodo, we will test out who Bing Webmaster Tools work, while still using third party link checker tools such as Majestic SEO in order to ensure clients links are properly managed.
