I need 50 unique articles written on the subject of search engine optimization. All articles must be checked with Copyscape and have to be original work. In general, I am trying to supply a blog of mine with articles on the subject of search engines. Any information you can throw together that pertains to SEO and search engines will be acceptable. These need to be written in English, proofread with accurate grammar. I will not accept anything written sloppily, please do not waste both of our time. Each article should be no more than 1500 words, but no less than 500 words. Each article must be titled appropriately.
