Use your keywords in the headings and make sure the first level (H1) includes your most important keywords. Never duplicate your title tag content in your header tag.
While it is important to ensure every page has an H1 tag, never include more than one per page. Instead, use multiple H2 - H6 tags.

No Description

This is an example of what your Title Tag and Meta Description will look like in Google search results.
While Title Tags & Meta Descriptions are used to build the search result listings, the search engines may create their own if they are missing, not well written, or not relevant to the content on the page.
Title Tags and Meta Descriptions are cut short if they are too long, so it's important to stay within the suggested character limits.

Alt Attribute

We found 23 images on this web page

No ALT attributes are empty or missing.

This table highlights the importance of being consistent with your use of keywords.
To improve the chance of ranking well in search results for a specific keyword, make sure you include it in some or all of the following: page URL, page content, title tag, meta description, header tags, image alt attributes, internal link anchor text and backlink anchor text.

Text/HTML Ratio

HTML to Text Ratio is: 11.4%

Text content size	7867 bytes
Total HTML size	68979 bytes

Code to text ratio represents the percentage of actual text on a web page compared to the percentage of HTML code, and it is used by search engines to calculate the relevancy of a web page.
A higher code to text ratio will increase your chances of getting a better rank in search engine results.

GZIP compression

Wow! It's GZIP Enabled.

Your webpage is compressed from 67 KB to 13 KB (81.3 % size savings)

Gzip is a method of compressing files (making them smaller) for faster network transfers.
It allows to reduce the size of web pages and any other typical web files to about 30% or less of its original size before it transfer.

WWW Resolve

Great, a redirect is in place to redirect traffic from your non-preferred domain.

Redirecting requests from a non-preferred domain is important because search engines consider URLs with and without "www" as two different websites.

IP Canonicalization

No your domain IP 104.26.8.150 does not redirect to betterexplained.com

To check this for your website, enter your IP address in the browser and see if your site loads with the IP address.
Ideally, the IP should redirect to your website's URL or to a page from your website hosting provider.
If it does not redirect, you should do an htaccess 301 redirect to make sure the IP does not get indexed.

XML Sitemap

Oh no, XML Sitemap file not found!
http://betterexplained.com/sitemap.xml

A sitemap lists URLs that are available for crawling and can include additional information like your site's latest updates, frequency of changes and importance of the URLs. This allows search engines to crawl the site more intelligently.
We recommend that you generate an XML sitemap for your website and submit it to both Google Search Console and Bing Webmaster Tools. It is also good practice to specify your sitemap's location in your robots.txt file.

Robots.txt

Good, you have Robots.txt file!
http://betterexplained.com/robots.txt

A robots.txt file allows you to restrict the access of search engine robots that crawl the web and it can prevent these robots from accessing specific directories and pages. It also specifies where the XML sitemap file is located.
You can check for errors in your robots.txt file using Google Search Console (formerly Webmaster Tools) by selecting 'Robots.txt Tester' under 'Crawl'. This also allows you to test individual pages to make sure that Googlebot has the appropriate access.

URL Rewrite

Good, all URLs look clean and friendly

Your site's URLs contain unnecessary elements that make them look complicated.
A URL must be easy to read and remember for users. Search engines need URLs to be clean and include your page's most important keywords.
Clean URLs are also useful when shared on social media as they explain the page's content.

Underscores in the URLs

Great, you are not using underscores (these_are_underscores) in your URLs

Great, you are not using ?underscores (these_are_underscores) in your URLs.
While Google treats hyphens as word separators, it does not for underscores.

Embedded Objects

Perfect, no embedded objects has been detected on this page

Embedded Objects such as Flash. It should only be used for specific enhancements.
Although Flash content often looks nicer, it cannot be properly indexed by search engines.
Avoid full Flash websites to maximize SEO.

Iframe

Oh no, iframe content has been detected on this page

Frames can cause problems on your web page because search engines will not crawl or index the content within them.
Avoid frames whenever possible and use a NoFrames tag if you must use them.

Domain Registration

Exactly how many years and months

Domain Age: 15 Years, 40 Days

Created Date: 8th-Jun-2006

Updated Date: 17th-May-2020

Expiry Date: 8th-Jun-2022

Domain age matters to a certain extent and newer domains generally struggle to get indexed and rank high in search results for their first few months (depending on other associated ranking factors). Consider buying a second-hand domain name.
Do you know that you can register your domain for up to 10 years? By doing so, you will show the world that you are serious about your business.

While there's no exact limit to the number of links you should include on a page, best practice is to avoid exceeding 200 links.
Links pass value from one page to another, but the amount of value that can be passed is split between all of the links on a page. This means that adding unnecessary links will dilute the potential value attributed to your other links.
Using the Nofollow attribute prevents value from being passed to the linking page, but it's worth noting that these links are still taken into account when calculating the value that is passed through each link, so Nofollow links can also dilute pagerank.
