Authority of Linking Domain# of Links from Separate C-Class IPHey everyone, I would like to know if any SEO Experts could enlighten me (us all who are seeking answers to that kind of questions) on what are the factors that are the most influential on a website's ranking ? Here are the few I've learnt and try to pay attention to when I am developing a website and start SEO campaigns : Keywords : As the first word of domain, In title tags (H1, H2, H3), In the description, The density on the page(%), The prominence of the keyword (having it appear in the first 100 words of the content), The keyword(s) order (affect it's ranking in RP depending on which order you place them). Domains : The age, The authority, The registration length (how long is it paid for in years), The history (A site with volatile ownership (via whois) or several drops may tell Google to “reset” the site’s history, negating links pointing to the domain.), Public or Private WhoIs (can be negative since there are speculations that it is used to "hide something), Domain Trust/TrustRank (its trust, measured by how many links away your site is from highly-trusted seed sites, is a massively important ranking factor http://backlinko.com/google-trustrank). Content : The magnitude of updated content, duplicated content, the length, helpful supplementary content (helpful supplementary content is an indicator of a page’s quality), grammar and spelling, syndicated content (if the content is scraped or copied from somewhere else), Bullets and Numbered Lists (bullets and numbered lists help break up your content for readers, making them more user-friendly. Google likely agrees and may prefer content with bullets and numbers I guess), multimedia (images, videos, and others could act as a content quality signal), Contact Us Page, Terms of Service and Privacy Pages (this helps tell Google your website is trustworthy). Code and other back-end elements : Sitemap, robot.txt, page layout, W3C Validation (I heard that many SEO experts consider W3C validation as a weak factor in ranking, on the other hand, I personally believe having a website with sloppy code and HTML errors could be a sign of poor quality site), keyword in URL, URL Strings, URL Length, URL Path (I read that a page closer to the homepage may get a slight authority boost!), site Uptime (if your site is often dropping or under maintenance then it might affect ranking), SSL Certificate (it is confirmed that they index SSL certificates and that they use HTTPS as a ranking signal), Breadcrumb Navigation, Server Location (may affect how high/low you rank in different countries), Duplicate Meta (this will affect ALL your page's ranking). Links : Outbound Link Quality (linking out to site with authority sends trust signals to Google) Outbound Link Theme (I read on https://moz.com/blog/external-linking-good-for-seo-whiteboard-friday that search engines may use the content of the pages you link to as a relevancy signal. Let's say that, if you have a page about cars that links to movie-related pages, this may tell Google that your page is about the movie Cars, not the automobile.) # ofOutbound Link (Too much 'do-follow' OBLs may “leak” PageRank, which can hurt that page’s rankings.) Internal Links Pointing to Pages, Broken Links, Affiliate Links, Linking Domain Age (getting backlinked by aged websites may be more powerful than new domains), # of Linking Root Domains (The number of referring domains is one of the most important ranking factors in Google’s algorithm another source out of https://moz.com/blog/guide-to-competitive-backlink-analysis "Link Root Domain" part w/ graph) # of Links from Separate C-Class IP, # of Linking Pages (The total number of linking pages, even if some are on the same domain, is a ranking factor.), Authority of Linking Domain (getting backlinks from higher authority domains may play a role in a link's importance, for example, a PR2 page link from a site with a homepage PR3 may be worth less than a PR2 page link from PR8 Yale.edu), Links from Competitors (Links from other pages ranking in the same SERP may be more valuable for a page’s rank for that particular keyword, I have experienced this case in 2 websites I made that ranked on Page 1 for the same Keyword giving links to each others and had a positive outcome). Edit: regarding the list above, I mixed both negative and positive impact points on SEO, but I'm sure you guys will be able to tell which one they are. I know this isn't all of it but I tried to put everything I remembered by the head from all my research and personal experience.
