In spite of the fact that had been using and utilizing many SEO techniques and strategies, I still seem not to be able to get the results that I want. I am currently indexed at Google and there are some instances that my website still doesn’t show up in searches. I want to expand my coverage and get indexed at several other good search engines out there. So far, my biggest challenge is on how to get listed or indexed at Yahoo. We know how difficult this is. I have been trying to do so for the past weeks but to no avail. Could anyone give me good pieces of advice about this matter?
