(All taken from: https://support.google.com/webmasters/answer/7451184)

Here are all of the things I found:

  • Using a single title across all of your site's pages or a large group of pages

  • Using extremely lengthy titles that are unhelpful to users. 

  • Stuffing unneeded keywords in your title tags. 
  • Using a single description meta tag across all of your site's pages or a large group of pages
  • Placing text in heading tags that wouldn't be helpful in defining the structure of the page.
  • Using heading tags where other tags like and may be more appropriate.
  • Erratically moving from one heading tag size to another. 
  • Excessive use of heading tags on a page. 
  • Very long headings. 
  • Using heading tags only for styling text and not presenting structure. 
  • Using invalid markup
  • Changing the source code of your site when you are unsure about implementing markup
  • Adding markup data which is not visible to users. 
  • Creating fake reviews or adding irrelevant markups. 
  • Creating complex webs of navigation links, for example, linking every page on your site to every other page.
  • Going overboard with slicing and dicing your content (so that it takes twenty clicks to reach from the homepage).
  • Having a navigation based entirely on images, or animations. 
  • Requiring script or plugin-based event-handling for navigation
  • Letting your navigational page become out of date with broken links. 
  • Creating a navigational page that simply lists pages without organizing them, for example by subject.
  • Allowing your 404 pages to be indexed in search engines (make sure that your web server is configured to give a 404 HTTP status code or - in the case of JavaScript-based sites - include a noindex robots meta-tag when non-existent pages are requested).
  • Blocking 404 pages from being crawled through the robots.txt file. 
  • Providing only a vague message like "Not found", "404", or no 404 page at all.
  • Using a design for your 404 pages that isn't consistent with the rest of your site.
  • Using lengthy URLs with unnecessary parameters and session IDs. 
  • Choosing generic page names like "page1.html". 
  • Using excessive keywords like "baseball-cards-baseball-cards-baseballcards.htm".
  • Having deep nesting of subdirectories like ".../dir1/dir2/dir3/dir4/dir5/dir6/page.html".
  • Using directory names that have no relation to the content in them. 
  • Having pages from subdomains and the root directory access the same content, for example, "domain.com/page.html" and "sub.domain.com/page.html
  • Writing sloppy text with many spelling and grammatical mistakes. 
  • Awkward or poorly written content. 
  • Embedding text in images and videos for textual content: users may want to copy and paste the text and search engines can't read it.
  • Dumping large amounts of text on varying topics onto a page without paragraph, subheading, or layout separation.
  • Rehashing (or even copying) existing content that will bring little extra value to users.
  • Having duplicate or near-duplicate versions of your content across your site.
  • Inserting numerous unnecessary keywords aimed at search engines but are annoying or nonsensical to users.
  • Having blocks of text like "frequent misspellings used to reach this page" that add little value for users.
  • Deceptively hiding text from users38, but displaying it to search engines. 
  • Writing generic anchor text like "page", "article", or "click here". 
  • Using text that is off-topic or has no relation to the content of the page linked to.
  • Using the page's URL as the anchor text in most cases, although there are certainly legitimate uses of this, such as promoting or referencing a new website's address.
  • Using excessively keyword-filled or lengthy anchor text just for search engines.
  • Creating unnecessary links that don't help with the user's navigation of the site.
  • 1.jpg" when possible—if your site has thousands of images you might want to consider automating the naming of the images.
  • Writing extremely lengthy filenames. 
  • Stuffing keywords into alt text or copying and pasting entire sentences. 
  • Attempting to promote each new, small piece of content you create; go for big, interesting items.
  • Involving your site in schemes53 where your content is artificially promoted to the top of these services.
  • Spamming link requests out to all sites related to your topic area. 
  • Purchasing links from another site with the aim of getting PageRank.
