Why Google penalized you site

Google penalty is a general term that refers to a negative impact on a website's search. Have you noticed that your website has recently lost its ranking position in search engine results?

Are many rules and possible infractions, and a comprehensive answer to this question is way beyond the scope of this article. But we will cover a few of the basic violations you’ll want to be aware of.  Avoid these to reduce the likelihood you’ll get penalized in the first place. 

1. Buying links. Buying links could certainly be seen as an attempt to manipulate PageRank, and therein lies the controversy..
2. Excessive reciprocal links. Swapping links was once an innocent marketing tactic until it started to be abused. If you’ve been exchanging lots of links with clients, it could be seen as a manipulation attempt.
3. Duplicate content. Any duplicate content on your site makes it less useful in Google’s view, and that could result in a penalty. Make sure your content is unique and well-written.
4. Links from sites in another language..
5. Keyword stuffed content. There are all kinds of weird and wonderful ‘rules’ about keyword density in content. The truth is that none of these rules are proven, and a very high keyword density is a flag for poorly written content
6. Footer links. Some web designers use footer links as a navigational aid; some try to manipulate.
7. Missing sitemap data. Make sure your XML sitemap is available.
8. Hidden links. All of the links on your site should be visible and useful to users. Anything that’s hidden is considered suspicious
9. Broken external links. If you don’t keep links up-to-date, Google will assume you don’t care about the user . Check links periodically
10. Scraped content. Sometimes website managers pull content from other sites in order to bulk our their own pages. Often, this is done with good intentions, and it may be an innocent error. But Google sees this as pointless duplication. Replace it with your own original content instead.
11. Hidden content. Less ethical optimization tactics include disguising text on a page to manipulate the theme or keyword weighting. It goes without saying that this is a big No 
12. Anchor text overuse. Switch out your forced, unnatural keyword links
13. Rented links. Some experts still believe rented links are valid and useful for SEO.
14. Affiliate links all over the place. Google isn’t necessarily opposed to affiliate websites, but a high number of affiliate links is a red flag that the content may not be up to scratch.
15. Overusing meta keywords. They are way too easy to manipulate. Make sure you use no more than five per page. 
16. Slow speeds..Hiding your sponsors. Having a sponsor is no bad thing. Plenty of sites wouldn’t exist without them. Don’t try to hide your sponsors
17. Robots.txt flaws. The robots.txt file should be used to tell search engines how to deal with your site.
18. Links to suspicious sites. Never associate yourself with a website that is doing something ethically or legally dubious. Hacking, porn and malware-ridden sites should be avoided. Also, try to remove links to other sites that have been penalized in the past, assuming you know about it.
19. Over-optimization. Google doesn’t like to see too much of a good thing. An over-optimization penalty usually means you’ve gone a step too far in your bid to obsessively out-SEO 
20. Too many outbound links. When linking to other websites, keep it natural. A high quantity of links is a sign that you’re swapping links with people for the sake of mutual SEO benefit.
21. Duplicate metadata. Some blogging tools and CMS platforms make it all too easy to create duplicate metadata by accident. While metadata isn’t a cause for a penalty on its own, it can be a sign of a duplicate content issue on your site.
22. Domain has a bad rep. You may have innocently purchased a domain with a bad history, and that could cause you problems when you try to build a new site around it.
23. Prominent ads. Advertising is OK when treated as a secondary concern. Ads should never dominate the page content or play second fiddle to an article or blog.
24. Beware of quick fixes. Don’t employ anyone that claims to have a magical, foolproof technique that will help to get your site to the top of the SERPs. The only way to rank well is to put in the groundwork over time.
