Title Tag Starts with Keyword: According to Moz , title tags that starts with a keyword tend to perform better than title tags with the keyword towards the end of the tag.

Keyword in Description Tag: Google doesn’t use the meta description tag as a direct ranking signal. However, your description tag can impact click-through-rate, which is a key ranking factor.

Keyword Appears in H1 Tag: H1 tags are a “second title tag”. Along with your title tag, Google uses your H1 tag as a secondary relevancy signal, according to results from one correlation study:

TF-IDF: A fancy way of saying: “How often does a certain word appear in a document?”. The more often that word appears on a page, the more likely it is that the page is about that word. Google likely uses a sophisticated version of TF-IDF.

Content Length: Content with more words can cover a wider breadth and are likely preferable in the algorithm compared to shorter, superficial articles. Indeed, one recent ranking factors industry study found that content length correlated with SERP position.

Page Loading Speed via Chrome: Google also uses Chrome user data to get a better handle on a page’s loading time. That way, they can measure how quickly a page actually loads to users.

Use of AMP: While not a direct Google ranking factor, AMP may be a requirement to rank in the mobile version of the Google News Carousel.

Entity Match: Does a page’s content match the “entity” that a user is searching for? If so, that page may get a rankings boost for that keyword.

Google Hummingbird: This “algorithm change” helped Google go beyond keywords. Thanks to Hummingbird, Google can now better understand the topic of a webpage.

Duplicate Content: Identical content on the same site (even slightly modified) can negatively influence a site’s search engine visibility.

Google states that: “Google Search uses breadcrumb markup in the body of a web page to categorize the information from the page in search results.”

Mobile Optimized: With more than half of all searches done from mobile devices, Google wants to see that your site is optimized for mobile users. In fact, Google now penalizes websites that aren’t mobile friendly

YouTube: There’s no doubt that YouTube videos are given preferential treatment in the SERPs (probably because Google owns it ).
