I have created PPT for my keyword and I had submitted it to ten different sites is it right or not...single file to different site is right or not for PPT in seo
In most of the ppt submission sites, ppt is submitted in form of images and text within it, doesn't crawl. The title, description provided for it's detail are being crawled by the search engines and showing in the results. Try to provide proper description that clearly describes the content of ppt. Also, it will give give much advantage if you modify the content and submit in place of the same content.
I do not think it is going to help much. The thing is that anyone can do activities like this. You should try to create an ebook or do a Podcast. It should not hurt you and it may drive very little traffic.
