HIGH
Your webpage contains URLs that are not SEO friendly!
HIGH
Your webpage does not contain any H1 headings. H1 headings help indicate the important topics of your page to search engines. While less important than good meta-titles and descriptions, H1 headings may still help define the topic of your page to search engines.
HIGH
The meta description tag is missing from your page. You should include this tag in order to provide a brief description of your page which can be used by search engines. Well-written and inviting meta descriptions may also help click-through rates to your site in search engine results.
HIGH
Your most common keywords are not appearing in one or more of the meta-tags above. Your primary keywords should appear in your meta-tags to help identify the topic of your webpage to search engines.
HIGH
Your website is not connected with social media using the API's provided by Facebook, Google +, Twitter, Pinterest, or using addthis.com
HIGH
The size of your webpage's HTML is 42.9 Kb, and is greater than the average size of 33 Kb. This can lead to slower loading times, lost visitors, and decreased revenue. Good steps to reduce HTML size include: using HTML compression, CSS layouts, external style sheets, and moving javascript to external files.
HIGH
Your website is not using a custom 404 error page. Default 404 error pages result in a poor experience - it can mislead users into thinking an entire site is down or broken, greatly increases the chance they leave your site entirely, and looks unprofessional. By creating a custom 404 error page, you can improve your website's user experience by letting users know that only a specific page is missing/broken (and not your entire site), providing them helpful links, the opportunity to report bugs, and potentially track the source of broken links in your site.
MEDIUM
A Google Analytics script is not detected on this page. While there are several tools available to monitor your site's visitors and traffic sources, Google Analytics is a free, commonly recommended program to help diagnose potential SEO issues.
LOW
Your DNS server is not using an SPF record. SPF (Sender Policy Framework) allows administrators to specify which hosts are allowed to send mail from a given domain by creating a specific SPF record or TXT record in the Domain Name System (DNS). You can find more information about SPF records here.
LOW
Your webpage is using inline CSS styles!

Most Common Keywords Test
  • There is likely no optimal keyword density (search engine algorithms have evolved beyond keyword density metrics as a significant ranking factor). It can be useful, however, to note which keywords appear most often on your page and if they reflect the intended topic of your page. More importantly, the keywords on your page should appear within natural sounding and grammatically correct copy.
