A clean URL structure makes it easier for search engines to crawl your web pages and then analyze and store your page content to display as a result of relevant search queries.

❖ Make sure to secure the site with HTTPS protocol.

HTTPS is also a Google ranking signal(announced in 2014). It is a secure HTTP version and a primary protocol for secure data transmission between a website and browser. It uses a Secure Sockets Layer – SSL to encrypt links. The URL of a website that uses SSL starts with: the ‘https://’ rather than ‘http://’and you can see a padlock. e.g.


Secure HTTPS websites are given preference over non-secure ones in search results. So, migrate your website to an HTTPS site today.

Broken links can cause a poor user experience and hurt your website authority. Broken/dead links point to the web pages that have been deleted without 301 redirects. So, whenever one clicks click a broken link, it doesn’t direct them to the correct or working URL.

Make sure that your site is free from any crawl errors. One can check the Coverage report to identify these errors, warnings, and excluded pages through Google Search Console.

❖ Update core metrics to improve the User Experience.

The key factors of Google’s Page experience update combine three core web vitals with the page experience signals like mobile-friendliness, page speed, safe browsing, etc.

To refresh, core web vitals are the user-centered metrics used by Google to quantify web usability. There are three Core Web vitals- LCP, FID, and CLS:

Largest Contentful Paint (LCP) tells about the loading performance of a page from the point when the user first clicks on a page link to when the content element loads on the screen. For a good user experience, it should be less than 2.5 seconds.

First Input Delay (FID) measures the first user interaction with the page. For a good user journey experience, it should be less than 100 ms.

Cumulative Layout Shift (CLS) measures the visual stability of page elements. a CLS of less than .1 seconds is good for a website.

You can find these ranking factors in the Google search console report. There are many tools available in the market to improve Core Web Vitals and your website speed. You can also consider some optimizations like upgrading the JavaScript performance, optimizing the browser image formats, implementing the lazy-loading techniques on non-critical resources, etc.

❖ Add structured data/schema markup.

Structured data, also known as schema markup, help search engines contextualize and understand your website content and rank it more accurately. It helps to display the information in the form of a rich snippet on the results page. Not only it improves the user experience but also the experience of the Search Bots to answer the user queries faster and efficiently. To create schema markup, one can use Google’s Structured Data Testing tool or any of the online schema markup generators. It is much easier than doing it manually.

❖ Check Temporary 302 Redirects.

302 is a simple temporary redirect that means a page is moved temporarily and directing to a new page for a short period. Whereas the 301 is a status code to tell that page is moved permanently. 302 redirect retains the original search engine ranking of a page and not impacting the SEO at all.  In addition, it is easier to implement and improves the user experience as well. You can locate the 302 redirects through the Site Audit report.

Note: Never use a 302 redirect if a page is permanently moved instead; prefer using 301.

❖ Ensure to submit an optimized XML sitemap.

An XML sitemap is simply a website blueprint that helps search engines to decide which pages should be crawled and indexed. Search engines support many different formats of sitemap, but the most commonly used is XML. It is especially useful for faster indexation in case a website has thousands of pages, new pages are frequently added, frequent changes are made to the existing pages, and a website lacks internal and external linking. You can find a sitemap on https://www.domain.com/sitemap.xml. Some of the WordPress plugins generate a sitemap as its standard functionality. Once a sitemap has been generated, submit it to Google Search Console and Bing Webmaster Tools. Don’t forget to refer sitemap in the robots.txt file.

❖ Create an optimized robots.txt file.

The robot.txt file, also known as the robot exclusion protocol, tells web robots to crawl the website pages. Usually, it prevents a certain section of the website from being crawled. In other words, hide some site sections from search engines. Find your site robots.txt at https://www.domain.com/robots.txt. Several WordPress SEO plugins allow users to create and edit their robots.txt file, but if a different CMS is used, you need to manually create the file and upload it to the root of your domain.
