Thank you for explain about white hat seo

Are you sure? Better you learn again what SEO is.

Most tend to neglect the value of a well crafted paragraph. Optimizing copy encourage the full use of the English language: its verb tenses, the alteration of prefixes and suffixes. Repetition of keywords proved poiintless after Inktomi, in today's SEO there is value in a synonymous keyphrase or an abbreviation, an antonym ... the search engine understands there is value in writing intelligently. Taking the time to write well implies the author intended it to be read, by humans. This is the art that differentiates the white hats from the rest of the SEO fluff.

Yes, these are white hat SEO techniques and these are according to the Search engines gudileness.
