We expect advertisements to be visible. However, you should not let the advertisements distract users or prevent them from consuming the site content. For example, advertisements, supplement contents, or interstitial pages (pages displayed before or after the content you are expecting) that make it difficult to use the website.

Regarding internal linking, i believe that in the case of two links pointing to an internal page, being one of those links in the group i mentioned above, they will considered only the one witch feed the algorithm with more information. In sites that have the menu before the content, it will be the second link. I think that’s the smart way for them to analyse all the links to better understand the destination page content. And they are smart 😉 .

A user-feedback poll is one great, easy way to help you better understand your customers. Kline claims, “Done incorrectly, these can be annoying for a user. Done well, it’s an excellent opportunity to help the customer feel that their opinion matters, while also getting needed insights to better market the company. One poll we ran for an e-commerce client helped us learn that 80% of potential customers cared more about the performance of the product than the price. [So,] we added as much helpful performance information to the website as we could.”

In February 2011, Google announced the Panda update, which penalizes websites containing content duplicated from other websites and sources. Historically websites have copied content from one another and benefited in search engine rankings by engaging in this practice. However, Google implemented a new system which punishes sites whose content is not unique.[36] The 2012 Google Penguin attempted to penalize websites that used manipulative techniques to improve their rankings on the search engine.[37] Although Google Penguin has been presented as an algorithm aimed at fighting web spam, it really focuses on spammy links[38] by gauging the quality of the sites the links are coming from. The 2013 Google Hummingbird update featured an algorithm change designed to improve Google's natural language processing and semantic understanding of web pages. Hummingbird's language processing system falls under the newly recognized term of 'Conversational Search' where the system pays more attention to each word in the query in order to better match the pages to the meaning of the query rather than a few words [39]. With regards to the changes made to search engine optimization, for content publishers and writers, Hummingbird is intended to resolve issues by getting rid of irrelevant content and spam, allowing Google to produce high-quality content and rely on them to be 'trusted' authors.
When referring to the homepage, a trailing slash after the hostname is optional since it leads to the same content ("https://example.com/" is the same as "https://example.com"). For the path and filename, a trailing slash would be seen as a different URL (signaling either a file or a directory), for example, "https://example.com/fish" is not the same as "https://example.com/fish/".
Commenting on blog posts written by industry experts with lots of followers can bring your website a lot of traffic. When you post a comment (most) blogs allow you to leave a link back to your site for other readers to check out – as long as you leave an insightful comment you WILL get traffic from your blog comments. Make sure you comment as quickly as possible when new blog posts go up. The higher in the comments you are the more clicks you’ll get. I have Google Reader setup to alert me when new blog posts are made on the industry blogs I follow and I comment immediately to lock in my first place spot.
If you are using Responsive Web Design, use meta name="viewport" tag to tell the browser how to adjust the content. If you use Dynamic Serving, use the Vary HTTP header to signal your changes depending on the user-agent. If you are using separate URLs, signal the relationship between two URLs by tag with rel="canonical" and rel="alternate" elements.
To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain. Additionally, a page can be explicitly excluded from a search engine's database by using a meta tag specific to robots (usually ). When a search engine visits a site, the robots.txt located in the root directory is the first file crawled. The robots.txt file is then parsed and will instruct the robot as to which pages are not to be crawled. As a search engine crawler may keep a cached copy of this file, it may on occasion crawl pages a webmaster does not wish crawled. Pages typically prevented from being crawled include login specific pages such as shopping carts and user-specific content such as search results from internal searches. In March 2007, Google warned webmasters that they should prevent indexing of internal search results because those pages are considered search spam.[47]
