Your HTML title tag appears in browser tabs, bookmarks and in search result pages.

Make your title tags clear, concise (50-60 characters) and include your most important keywords.

Great, your meta description contains between 70 and 320 characters (spaces included).

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).

Check your Google Search Console account (Click 'Search Appearance', then 'HTML Improvements') to identify any issues with your meta descriptions, for example, they are too short/long, or duplicated across more than one page.

This is a representation of what your Title Tag and Meta Description will look like in Google search results.

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.

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 Keyword Cloud provides an insight into the frequency of keyword usage within the page.

It's important to carry out keyword research to get an understanding of the keywords that your audience is using. There are a number of keyword research tools available online to help you choose which keywords to target.

Keyword consistency is the use of keywords throughout the different elements of the webpage. Consistent keyword use helps crawlers index your site and determine relevancy to search queries.

The table above highlights the most frequently used keywords on your page and how consistently you're using them.

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 most or all of your images have alternative text. Check the images on your website to make sure accurate and relevant alternative text is specified for each image on the page. Try to minimize the number of alt text characters to 150 or less (including spaces!) to optimize page load times.

We've discovered 4,016,692 pages in Google's index for zing.vn.

A low number can indicate that bots are unable to discover your pages, which is commonly caused by bad site architecture & internal linking, or you're unknowingly preventing bots and search engines from crawling & indexing your pages. An unusually high number could be an indication of duplicate content due to URL parameters.

Make sure your website's XML sitemap is present and that you've submitted it to the major search engines. Building backlinks to your website's internal pages will also help bots to discover, crawl and index them, while building authority to help them rank in search results at the same time.

Check Index Status and Crawl Errors in Google Search Console to track the status of your crawled/indexed pages.

If you use parameters in your URL like session IDs or sorting and filtering, use the rel="canonical" tag tag to tell search engines which version of those pages is the original.

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.

Broken links send users to non-existent web pages. They hurt a site's usability and reputation, which impacts SEO.

Fortunately your page doesn't contain any broken links.

Be proactive in checking your pages to make sure they don't have any broken links.

Search engines see www.zing.vn and zing.vn as different websites. This means they could see a large amount of duplicate content, which they don't like.

Fortunately your website redirects www.zing.vn and zing.vn to the same site.

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.

We checked zing.vn/robots.txt didn't find a robots.txt file. Use Google Search Console to submit and test your robot.txt file. You can also test individual pages to make sure Google isn't crawling any restricted files.

XML sitemaps contain the list of your URLs that are available to index and allow the search engines to read your pages more intelligently. They can also include information like your site’s latest updates, frequency of changes and the importance of URLs.

Be 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 sure to be consistent in using your preferred URLs (with or without www.), correct protocols (http vs. https) and trailing slashes. You should also use your robots.txt file to point search engine crawlers to the location of your sitemap.

Great, you aren't using ‪underscores (these_are_underscores) in your URLs.

Google sees hyphens as word separators while underscores aren't recognized. So the search engine sees www.example.com/green_dress as www.example.com/greendress. The bots will have a hard time determining this URL's relevance to a keyword.

Great, you aren't using Flash or frames on your site.

While it often looks nicer, Flash content can't be properly indexed by search engines. Maximize your SEO efforts by avoiding Flash.

Search engines also have problems with frames because they can't crawl or index the content within them. Avoid them if you can and use a NoFrames tag when you can't.
