A spam score of 30 or below is considered a low spam score.
To reduce your MOZ spam score you should look for and identify any low quality and spammy backlinks and then either disavow or remove the low quality or spammy backlinks.
And also build up high quality backlinks from reputable websites to diversify your link profile and improve your websites on page SEO as well as technical health and create high quality and original content to increase your websites trust and authority.
You can use Moz's link Explore or other webmaster tools to find any low quality or spammy or suspicious backlinks that point to your site.
And if you can't get the websites to remove the spammy links you can use Google's Disavow Tool to signal to search engines that you want to ignore the spammy and low quality backlinks.
A good Moz spam score is 1% or under 30%.
Moz spam scores between 31% to 60% indicate a medium spam risk and a Moz spam score of between 61% to 100% indicate a high risk of spammy characteristics of the website although the Moz spam score is not a direct ranking factor in search engines but is a helpful guide to identify any potential issues on your website which include toxic backlinks, low quality content etc.
The lower your Moz spam score the better.
The Google Spam Score is a metric that was created by Moz and other third party SEO tools, and is a score that is used to estimate how likely a website's link profile as well as other on page factors are to be flagged as spam by Google.
The Google Spam Score which is more commonly known as a Moz spam score is a third party score and opinion that is based on proprietary algorithms and not a direct indicator of Google's own penalties or rankings, although it can also highlight some potential issues with the quality of your website, which Google's own algorithms may also consider.
Having a high spam score above 30 percent can decrease your chances of ranking in Google, and having a spam score below 30 percent means that you're more likely to rank in Google.
Although Google itself does not use the Moz spam score or other third party tools as they use their own algorithm when determining your spam score and how they should rank your website or if they should rank your website at all.
To improve your website ranking on Google and get Google to rank your website higher you need to create high quality and relevant content that solves the searchers problems.
Also use targeted keywords in your titles, descriptions and body and build quality backlinks from authoritative sites.
And ensure that your website provides it's users with a positive user experience by improving the site loading speed and ensure the site is mobile friendly.
You can also analyze your websites performance by using tools such as Google Search Console and Google Analytics.
And also use proper image optimization and a clear site structure.
Write content for users and not just for search engines as Google ranks websites that solve a users problems and not just content designed for the search engines.
And ensure you're writing original content and not just copying content that others have already written and integrate your target keywords naturally into the contents body text, headings, title tags and page URLs but don't use keyword stuffing as it can hurt your rankings.
Google uses at least 200 factors to rank websites.
Although the exact number of ranking factors that Google uses to rank websites is not officially disclosed publicly and the number of Google ranking factors still continues to evolve.
The factors that Google uses for ranking websites are also categorized into areas such as site quality, relevance of content, user experience, website authority, website trustworthiness, mobile friendliness, page speed, content quality and whether or not the content answers the searchers questions.
The main thing that Google uses to rank websites is how well the content matches the search intent of the search query and how well the content is written and if it's made for people and not just search engine optimized.
The first thing that Google considers when ranking a website is the quality of the websites content as well as the relevance of the content.
When ranking content and websites in it's search engine, Google seeks to provide it's users with reliable, helpful and comprehensive information and content which directly answers the searchers search queries.
Google rewards and ranks high content which is valuable and people first instead of just search engine optimized content.
If the content does not answer the searchers query it will either not rank or may be pushed down later in the rankings if Google detects that people are not finding the content helpful such as by bouncing from the content quickly.
For your websites content to rank high in Google search is needs to be unique and provide new insights and offer substantial value to the searcher.
The content must also be created for people, and solve real user problems and satisfy the search query's intent.
And Google also prefers to rank content higher that provides complete answers to someone's questions on a given topic they are searching for answers for.
Google is also now ranking user generated content like question and answer websites better including websites like reddit, quora and even this website higher than blog content that just writes content that's not helpful.
Blogs can still rank good and high in Google but the content must be of high quality and not just regurgitated content.
