HTML title tags appear in browser tabs, bookmarks and in search results.

It looks like your title tag is a little outside the ideal length. Since they are one of the most important on-page SEO elements you should make your title tags between 20 and 70 characters including spaces (200 - 569 pixels). Make sure each page has a unique title and use your most important keywords. For internal pages start your title tags with your most important keyword(s).

Great, your meta description contains between 70 and 160 characters spaces included (400 - 940 pixels).

A good meta description acts as an organic advertisement, so use enticing messaging with a clear call to action to maximize click-through rate. They allow you to influence how your web pages are described and displayed in search results.

Ensure that all of your web pages have a unique meta description that is explicit and contains your most important keywords (these appear in bold when they match part or all of the user’s search query).

Use WooRank's Site Crawl to check thousands of pages for meta descriptions that are too long, too short or duplicated across multiple web pages.

This is a representation of what your title tag and meta description will look like in Google search results for both mobile and desktop users. Searchers on mobile devices will also see your site's favicon displayed next to the page's URL or domain.

Search engines may create their own titles and descriptions if they are missing, poorly written and/or not relevant to the content on the page and cut short if they go over the character limit. So it’s important to be clear, concise and within the suggested character limit.

Check your title tag and meta description to make sure they are clear, concise, within the suggested character limit and that they convey the right message to encourage the viewer to click through to your site.

Great, your website is structured using HTML headings (<H1> to <H6>).

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, only include more than one per page if you're using HTML5. Instead, use multiple <H2> - <H6> tags.

This data represents the words and phrases that your page appears to be optimized around. We use what’s called “natural language processing" (NLP), which is a form of artificial intelligence that allows computers to read human language, to do this analysis.

The numbers next to each word or phrase represents how often we detected them and their variants on the page.

Are these the keywords you want to target for your page? If so, great! Track your site’s rankings in Google search results using WooRank’s Keyword Tool.

If these keywords aren’t relevant to your page, consider updating your content to optimize it for your target keywords.

Alternative text allows you to add a description to an image. Since search engine crawlers cannot see images, they rely on alternative text attributes to determine relevance to a search query. Alternative text also helps makes an image more likely to appear in a Google image search and is used by screen readers to provide context for visually impaired users.

It looks like you're missing alternative text for 39 images on blogi.co.kr. Check the images on your website to make sure accurate and relevant alternative text is specified for each image on the page.

Try to keep your alternative text to a simple, one-sentence description of what's in the image.

Links pass value from one page to another. This value is called 'link juice'.

A page's link juice is split between all the links on that page so lots of unnecessary links on a page will dilute the value attributed to each link. There's no exact number of links to include on a page but best practice is to keep it under 200.

Using the Nofollow attribute in your links prevents some link juice, but these links are still taken into account when calculating the value that is passed through each link, so using lots of NoFollow links can still dilute PageRank.

Check your site's internal linking using Site Crawl.

Your website hasn't specified a language yet. Use the META Language Attribute to declare the intended language of your website. We've detected that your website is currently in -.

Here are some tips for multilingual websites:

• Define the language of the content in each page's HTML code.
• Specify the language code in the URL as well (e.g., "mywebsite.com/fr/mycontent.html").
• Use hreflang tags to specify language and country for Google, and the "content-language" meta tag to specify the language and country for Bing.

Search engines see www.blogi.co.kr and blogi.co.kr as two different websites with the same content. This causes them to see a lot of duplicate content, which they don't like.

Right now your website is not directing traffic to www.blogi.co.kr and blogi.co.kr to the same URL. It is crucial that you fix this.

Use the rel="canonical" tag to tell search engines which is the definitive version of your domain. Use a 301 redirect to divert traffic from your secondary domain.

This issue can be caused by problems with a website's SSL configuration. Check your site's SSL configuration for any errors.

If you need help resolving issues with your SSL configuration, consider using a professional service to set it up for you.

A robots.txt file allows you to restrict the access of search engine crawlers to prevent them from accessing specific pages or directories. They also point the web crawler to your page’s XML sitemap file.

Your site currently has a robots.txt file. You can use Google Search Console's Robots.txt Tester to submit and test your robots.txt file and to make sure Googlebot isn't crawling any restricted files.

See the pages you've disallowed with your robots.txt file with Site Crawl.

We checked the robots.txt file for blogi.co.kr but couldn't find an XML sitemap. Specifying the location of your XML sitemaps in your robots.txt file ensures that search engines and other crawlers find and access it easily each time they access your website.

Learn more about adding your XML sitemap to your robots.txt file.

If you haven't created a sitemap yet, we recommend you generate one for your site and submit it through both Google Search Console and Bing Webmaster Tools. Usually, your XML sitemap would be found at blogi.co.kr/sitemap.xml

Make sure to only include the pages you want search engines to crawl, so leave out any that have been blocked in a robots.txt file. Avoid using any URLs that cause redirects or error codes and be consistent in using your preferred URLs (with or without www.), correct protocols (http vs. https) and trailing slashes.

URL parameters are used to track user behaviors on site (session IDs), traffic sources (referrer IDs) or to give users control over the content on the page (sorting and filtering). The issue with URL parameters is that Google sees each unique parameter value as a new URL hosting the same thing - meaning you could have a duplicate content problem. Sometimes, it’s able to recognize these URLs and group them together. It then algorithmically decides which URL is the best representation of the group and uses it to consolidate ranking signals and display in search results. You can help Google recognize the best URL by using the rel="canonical" tag.

Use the URL Parameters Tool in Google Search Console to tell Google how your URL parameters affect page content and how to to crawl URLs with parameters. Use this tool very carefully - you can easily prevent Google from crawling pages you want indexed through overly restrictive crawling settings, especially if you have URLs with multiple parameters.

Check the On-Page section of Site Crawl to identify any duplicate content issues.

The hreflang tag is an HTML tag that tells search engines which languages and (optionally) countries a page's content is relevant for. Hreflang tags also tell search engines where to find the relevant content in alternate languages.

If your website targets users all around the world, using hreflang tags will help make sure the right content is being served to the right users.

The value of the hreflang attribute identifies the language (in ISO 639-1 format) and optionally a region in ISO 3166-1 Alpha 2 format of an alternate URL.

Use WooRank's Site Crawl to perform a thorough check on hreflang validity across a website.

Using underscores in your URL makes it hard for search engines to determine your site's relevance to a search. Google sees hyphens as word separators while underscores are ignored. So the search engine sees http://www.maru.net/blogi/html/mypage/my_use.html as all one word. Use hyphens in your URLs instead: http://www.maru.net/blogi/html/mypage/my-use.html.

We've detected underscores in your URLs. Change underscores to hyphens to maximize your SEO.

Mobile friendly pages make it easy for users to complete their objectives and common tasks and use a design or template that is consistent across all devices (uses responsive web design).

Google released a new mobile ranking algorithm that expanded the use of mobile-friendliness in its mobile search rankings. With almost half of all Google search queries originating on a mobile device, it is important to make sure your mobile site is optimized for these users.

This is how your website appears when displayed on different mobile devices.

With more than half of all Google search queries originating on a mobile device, it is important to make sure your mobile site is optimized for these users.

Your page’s links and buttons are too small and/or too close to be easily clicked on a mobile device. The average fingertip area is 48 pixels in width and height. Tap targets should also be spaced enough so that a user's finger pressing on one link or button does not inadvertently touch another one. The minimum required space between tap targets is 8 pixels on all sides.

Use Google's Lighthouse tool to get a detailed look at all of your too tap targets that are too small and too close together.

Great, your website does not embed any special types of web content, such as Flash, Silverlight or Java, so your content can be accessed on all devices.

At least 60% of your page’s font size is 12 pixels or greater.

The viewport is an element of a page’s responsive design. It’s the area of a webpage visible to the user and varies between devices.

It looks like blogi.co.kr could be missing a meta viewport.

Use the meta viewport tag in the <head> to set the viewport to the device’s screen size. It should look like this: <meta name="viewport" content="width=device-width, initial-scale=1.0">.

Mobile or responsive frameworks are an important part of website optimization as they assist developers in creating applications which are applicable to multiple devices.

AMP is an open-source library that provides a straightforward way to create web pages that are compelling, smooth, and load near instantaneously for users.

Check your AMP markup with the AMP validator.

Get started using Schema.org vocabulary and marking up your webpage.

Schema.org is a set of vocabularies used to add meaning to the information on a webpage in a way that is readable by machines (Google). Schema.org vocabularies include attributes for entities, relationships between entities and actions.

Learn more in Google's intro to structured data. Structuring data on your pages can help increase website traffic and improve audience engagement. Schema.org vocabulary can be added to a page using many different formats, including RDFa, Microdata and JSON-LD.

Facebook developed the Open Graph protocol to enable the integration of any web page with its social media platform. Other social media platforms have also adopted the protocol, allowing you to control how your web pages are presented when shared across social media.

Check out Facebook's Guide to Sharing for Webmasters to learn how to add Open Graph tags.

Use the Sharing Debugger to check what information appears when shared on Facebook and the Twitter Cards Validator to do the same for Twitter.

Designed for humans first and machines second, microformats use code (HTML/XHTML tags) originally intended for other purposes to add context to the content on a webpage. This helps machines (like Google!) to understand certain information (contact information, geographic coordinates, calendar events, etc.) intended for humans.

We don’t recommend adding plain text/linked email addresses to your webpages, as malicious bots scrape the web in search of email addresses to spam. Instead, consider using a contact form.

Using an SSL certificate creates an encrypted connection between your visitor's browser and your website's server adding an extra layer of security. In 2014, Google announced that HTTPS would become part of their ranking algorithm and since your website is not HTTPS, it will likely rank below your HTTPS competitors. When moving to HTTPS, follow these best practices for a smooth transition:

• Use a serious issuer to purchase your SSL certificate
• Redirect all of your HTTP pages to the HTTPS version of your website
• Use HTTP Strict Transport Security in your headers
• Renew your SSL certificate every year, before it expires
• Make sure that all of your content (CSS, etc.) is linked to HTTPS
• Update your XML sitemap to ensure the URLs include HTTPS and update the robots.txt file to reference this version
• Register the HTTPS website in Google & Bing Search Console/Webmaster Tools

Your server's IP address has little impact on your SEO. Nevertheless, try to host your website on a server which is geographically close to your visitors. Search engines take the geolocation of a server into account as well as the server speed.

Use DNSstuff for comprehensive reports on your server.

Get to know the technologies used for your website. Some codes might slow down your website. Ask your webmaster to take a look at this.

Web analytics let you measure visitor activity on your website. You should have at least one analytics tool installed, but It can also be good to install a second in order to cross-check the data.

Popular Analytics Tools Include: Google Analytics, Quantcast™, AdobeAnalytics™, Piwik™, chartbeat™, Clicky™, ClickTale™, etc.

The Doctype is used to instruct web browsers about the document type being used. For example, what version of HTML the page is written in.

Declaring a doctype helps web browsers to render content correctly.

Specifying language/character encoding can prevent problems with the rendering of special characters.

Keep your URLs short and clean and avoid long domain names when possible.

A descriptive URL is better recognized by search engines. A user should be able to look at the address bar and make an accurate guess about the content of the page before reaching it (e.g., http://www.mysite.com/en/products).

Keep in mind that URLs are also an important part of a comprehensive SEO strategy. Use clean URLs to make your site more "crawlable" by Google.

Resource: Search for a good domain name. If no good names are available, consider a second hand domain. To prevent brand theft, you might consider trademarking your domain name.

Favicons are the small icons that represent a website, company and/or brand. They can be displayed (among other instances) in browser tabs or bookmarks. Google also displays favicons in a page's search snippet in mobile search results.

You can see how your site's favicon appears in search results in the Google Preview above.

Make sure your favicon is consistent with your brand to help improve visibility.

404 error pages are displayed when the page you are trying to open can't be found on the site's server for a variety of reasons.

It looks like blogi.co.kr doesn't have a customized 404 error page. This makes your site less user friendly. Generic 404 error pages strand users on a page with no links or suggestions of what to do next.

Use a custom 404 page to reduce customer frustration and link to other pages on your site. Make sure it returns the 404 http status code.
