Alternatively, one can assume each entity appearing in the carousel would be there regardless of whether they occurred frequently or infrequently on the same page together.

One of the key mechanisms Google uses to determine which entity and relationship are the most important is the freshness (how recent are the co-relations we discussed above), as well as the click-through rate on related queries combined with what users type in after a query.

Authoritative sites, especially those related to a specific subject matter, are given a higher priority in determining the relationships between entities.

If you operate a hotel in New York City, and that hotel name is frequently referenced on pages with the entity “hotel,” the relationship between the brand and the word “hotel” will be strengthened.

Further, if the hotel also exists on pages optimized for “New York City,” that entity relationship will be reinforced whether there is an active link or not. Even if topically unrelated pages use the phrase “New York City” and the name of the hotel, the relevance score goes up.

Continuing with my hotel example, having said “hotel” on a page with competing brands would, by my logic, assist in boosting the strength of the relationship for “hotels.”But if the page is also about dining and activities in New York, the relationship may soften.There is no information I know of to suggest whether entity association is an on-and-off, relative-or-not scenario or whether the more entities referenced, the less any one is valued. This would make sense, and if that is the case, then pages with a focus would logically reinforce a specific entity association more than a general page.

the closer two terms appear on a page, the stronger the relationship association is.

Wikipedia uses nofollow attributes on its outbound links, yet those links pass a powerful signal.

Pages will not be transcoded if the user is using a fast client.

Opting out of Web Light If you do not want your pages to be transcoded, set the HTTP header "Cache-Control: no-transform" in your page response.

Google shows faster, lighter pages to people searching on slow mobile clients. To do this, we transcode (convert) web pages on the fly into a version optimized for slow clients, so that these pages load faster while saving data.

Unlike AMP, site owners cannot create their own Web Light pages

Overall, moving into a preexisting Featured Snippet is harder than we may have thought. Google, on average, oscillates between just two URL options. 

Featured Snippets are made for informational queries. When information meets product/service, URL behavior within the Featured Snippet appears to change. Google moves URLs in and out of the Featured Snippet significantly more often than for the informational queries I looked at. E-commerce sites looking to score Featured Snippets may want to consider the value of a "snippet win," factor that into their overall strategy, and track such URLs very carefully. 

Leverage content you’re already creating and posting in all the other places that customers find you.

There's a workaround that forces Google to autocomplete the middle of the query:

Quora is undoubtedly one of the largest sources of questions out there.

Type [brandname ?] (with the space in-between) into Twitter's search box and you'll see all questions people are asking when discussing your topic / brand / product.

You can use Cyfe to monitor the #redditama hashtag in combination with your core term. Or you can set up an alert inside My Tweet Alerts.

Create a separate FAQ section to address and explain basic questions Identify and optimize existing content to cover the identified questions Add Q&A to important landing pages (this may help get product pages featured in Google).

Researching questions is an ongoing process: You need to be constantly discovering new ones and monitoring social media for real-time ideas

If your image is of a specific product, include both the full product name and the product ID in the alt tag so that it can be more easily found.

n general: if a keyword could be useful for finding something that is on the image, include it in the alt tag if you can.

every publisher in the world could kill it on their SEO strategy if they simply spent lots of time trying to make content that people are looking for and made sure that they maintained a fast, easy-to-navigate. and well-maintained website
