1. Put Out Quality Content
Google is frequently used by people to find information, and if your content falls short of their expectations, site visitors will quickly click the back button.
Your pages won't rank if your website is cluttered with unnecessary content or provides a bad user experience. However, you stand a much better chance of ranking if you deliver excellent content and a fantastic user experience.
Start by auditing the content of your website. Go through each page and assign a rating based on the value of the information it contains. Make sure to note any improvements you can make as well.
As an alternative, you can examine the average visit durations for each page. Poor engagement is evident if visitors arrive on a page but leave right away. Enter your Google Analytics account, select Content & Site Content, and sort by All Pages. Here, you can quickly sort your pages using various metrics.
A quality content is something that is written for your audience, unique and engaging, as well as works towards quality over quantity, thus increasing visitor engagement.
2. Build Quality links to your pages
A link can be seen as a vote as when from a relevant source it will carry far more weight than a link from a spammy source. In fact, an excessive amount of the latter is one of the main reasons for ranking penalties, and Google's Penguin update specifically addresses this issue.
Few effective strategies to build and attract quality links to your pages could be
- Creating engaging content that provides value for your target audience.
- Write guest blogs that involves submitting content to other blogs in your industry with a link back to your site.
- Build local citations about your business consisting of its name, address, and phone number.
- Add a link to your social media profile as they are great places to insert links to your site and to build a following.
3. Create a great mobile experience
Use Google's Mobile-Friendly Test tool to verify that your website is mobile-optimized and simultaneously observe how it operates. This tool works wonders for displaying how your website appears on a mobile device and notifying you of any loading or processing issues.
Verify that the content of your mobile page matches that of your desktop site if you have separate URLs for your mobile site.
4. Check your technical SEO
On both your desktop and mobile versions, be sure to use structured data and metadata.
Edit duplicate content as it is particularly risky for e-commerce websites. Use canonical URLs in these situations to inform Google which version of each page to rank in the SERPs.
Ascertain that your technical SEO & off-page SEO are in good shape and that there are no underlying problems.
5. Concentrate on your local regions
Use on-page SEO and other strategies to make sure Google understands the location of your company as well as other local ranking factors.
Consider creating media and content that defines your company with a particular area, like a neighborhood, community, or city. This will enhance your local SEO.
Sign up for Google My Business to control how your company's information appears in Google search results. Create and maintain profiles on additional significant directories.
Make sure your location information is consistent across all your web properties, like your website, social media, and any other listings.
The most recent Google updates may seem like a lot of work and detail to a business owner and marketer. However, it's crucial to keep in mind that Google, just like you, wants to create a fantastic user experience. These algorithmic changes eliminate content that is disorganized, low-quality, and illegal. That content competes with your business and marketing content in addition to filling up your search queries.
In conclusion, these Google updates are beneficial, and it is up to you to continue learning and applying what you have learned.
