This makes it easy for search engines to find all of your content. It provides reports and data to help you understand how your pages appear in search results. You also get to see the actual search terms people are using to find your website, how each page appears in the search results, and how often your pages are clicked. You can then plan your content strategy accordingly. Google Search Console also alerts you when there is something wrong with your website, like when search crawlers are unable to access it, find duplicate content, or restricted resources. After that you need to click on the Add Sitemap button. Once you have successfully added your sitemap, it will appear as pending.
The recipe of this score is kept secret so that people cannot game the results. However, the most common signals of authority are links. You should make it a habit to interlink your own posts whenever possible. If you have multiple authors, then create a pre-publish blog post checklist that requires them to interlink at least 3 other blog posts.
This will help you boost your pageviews, increases the time users spend on your site, and ultimately will improve the SEO score of your individual blog posts and pages. Engaged users means more links back to your site, more traffic, and improved SEO. Spammers submit comments with bad links which could affect and even ruin your search rankings.
This is why we recommend everyone to start using Akismet. It is one of the two plugins that come pre-installed with every WordPress site, and it helps you combat comment spam. If Akismet alone is unable to handle comment spam, then see these tips and tools to combat comment spam in WordPress.
If your blog posts attract a lot of genuine, spam-free comments, then you should pat yourself on the shoulder for building such an engaging website! However, too many comments on a post can make it load slower which also affects your search engine rankings.
Keep reading below to find out more about how speed affects SEO.
See our tutorial on how to paginate comments in WordPress. This helps you save link juice.
This will allow you to easily add nofollow to external links. By default, it shows the full article content on all these pages. Full articles also make your archive pages load slower. Showing full articles everywhere also affects your page views.
For example, users who subscribe to your RSS feed will be able to read the full article in their feed reader without ever visiting your website. The easiest way to solve this is by showing summaries or excerpts instead of full articles. Web usability experts believe that users decide whether they want to stay or leave within few seconds of visiting a website.
That means that as a website owner, you only have a few seconds to present your content and engage users. Search engines like Google admit that they rank faster websites higher than slow loading websites. If you are not careful with image sizes and quality, then they can slow down your website.
See our guide on how to speed up WordPress by optimizing images for the web. Another trick you can use to optimize your images for search engines is to use descriptive title and alt tags. These tags help search engines understand what your image is about. They also help users with visual impairment as their screen readers can read the alt and title tags to them. WordPress allows you to add title and alt tags when you upload an image.
If you are a photographer or add a lot of images to your WordPress site, then you need to use a gallery plugin. We recommend using Envira Gallery. This means that the security of your WordPress site is crucial for good rankings. This adds an additional security layer to your WordPress site. Categorical data can also take on numerical values Example: 1 for female and 0 for male.
Nominal Data Nominal values represent discrete units and are used to label variables, that have no quantitative value. Note that nominal data that has no order. Therefore if you would change the order of its values, the meaning would not change. Ordinal Data Ordinal values represent discrete and ordered units. You can see an example below: Note that the difference between Elementary and High School is different than the difference between High School and College.
This is the main limitation of ordinal data, the differences between the values is not really known. Because of that, ordinal scales are usually used to measure non-numeric features like happiness, customer satisfaction and so on.
Numerical Data 1.
In other words: We speak of discrete data if the data can only take on certain values. It basically represents information that can be categorized into a classification.
An example is the number of heads in coin flips. You can check by asking the following two questions whether you are dealing with discrete data or not: Can you count it and can it be divided up into smaller and smaller parts?
An example would be the height of a person, which you can describe by using intervals on the real number line. Interval Data Interval values represent ordered units that have the same difference.
Therefore we speak of interval data when we have a variable that contains numeric values that are ordered and where we know the exact differences between the values. That means in regards to our example, that there is no such thing as no temperature. With interval data, we can add and subtract, but we cannot multiply, divide or calculate ratios. Ratio Data Ratio values are also ordered units that have the same difference. Ratio values are the same as interval values, with the difference that they do have an absolute zero.
Good examples are height, weight, length etc. Why Data Types are important? Datatypes are an important concept because statistical methods can only be used with certain data types.
You have to analyze continuous data differently than categorical data otherwise it would result in a wrong analysis. Therefore knowing the types of data you are dealing with, enables you to choose the correct method of analysis.
