I have optimized the content for the keyphrase “frosted window film in Salt Lake City,” ensuring the first sentence of the blog introduces the keyphrase. I maintained approximately 1% keyphrase density across the blog, with natural integration at strategic points.

Additionally, the provided links were embedded using the guidelines:
1. The link to the decorative tinting page was embedded with the anchor text “Salt Lake City” in a relevant section regarding the local benefits and needs for the window film.
2. A link to an external resource discussing the uses of window film was subtly included to enrich content value and provide readers with additional design ideas.
3. The contact page link was embedded in the concluding section where readers are encouraged to reach out to Salt Lake Window Tinting, using the appropriate anchor text for ease of navigation.

HTML markup including heading tags for sections and link tags for the URLs were properly utilized to format the blog entry for online publication, enhancing SEO and readability.
