keywords that don't go out of stylle

I know most keywords rise and fall in popularity, but are there certain keywords and phrases that are always popular? It seems like these would be the best to include in a website for SEO.

well typically seasonal keywords will last for the season but most keywords are lasting. its a better idea to find as relevant as possible keywords to your content or products. once you have relevant keywords you can then see how saturated and competitive they are to refine your list.
