Here are the top mobile SEO mistakes you need to avoid if you want to earn better positions in theSERPs, drive more traffic to your mobile site, and keep your mobile visitors happy.

1.Slow Site Speed
Page load speed is an important Google ranking factor.But it’s also important to the people who will visit your site.

*Minimize requests and redirects:Keep pages clean and simple. Eliminate as many 301 redirects as possible, remove unnecessary elements from your page, optimize your HTML code, and minify anything that might slow site speed like CSS and JavaScript.
*Resize and compress images:You can use built-in tools in WordPress to automatically resize images for you, and tools like compressor.io to compress your file size.
*Check your hosting solution:Cheap third-party hosting solutions won’t give you the site speed you need to host huge volumes of traffic.This is especially true for e-commerce.
*Check your progress: Use Google’s PageSpeed Insights as a quick and easy check of your website’s performance.

2.Blocked Files
Googlebot should be able to crawl your website like an average user, which means restricting access toJavaScript, CSS, and image files on your website can potentially harm your rankings.

3.Interstitials Ads
Any page that provides a poor user experience could rank lower in organic search.This includes:
*Popups that cover a page’s main content, regardless of whether that occurs as soon as a user clicks through from Google search results or occurs as users scroll through the page.
*Standalone interstitials that are difficult to dismiss — especially if accidentally clicking these interstitials redirects you to a new page.
*Deceptive layouts, where the above-the-fold portion tricks users into thinking they’re viewing an interstitial.Note that there are some exceptions to this rule.Interstitial ads that are not adversely affected by the new ranking signal include:
*Legally necessary interstitials, including those for age verification and cookie usage.
*Login dialogs for unindexable content (e.g., private content like emails and content behind paywalls).
*Reasonably sized banners (e.g., the app install banners provided by Safari and Chrome). Generally, these take up no more than 20 percent of a screen.
*Check your website’s robots.txt file to see if any essential elements are disallowed.

4.Unplayable Content
Before you include video or multimedia on your page, consider how it will affect your site speed and whether your video-embedding is playable on all devices.Also, include a transcript whenever possible. This will assist both Google (for indexing) and users who need closed captioning.

5.Bad Redirects/Cross Links
Faulty redirects are a major issue in websites that haven’t been optimized for mobile.This is especially true on websites with separate desktop and mobile URLs.

Common areas of improvement include:
*If a mobile user mistakenly lands on the desktop version of your website, redirect them to the mobile version of the page they were seeking.They should not be redirected back to your mobile site’s homepage.
*If you do not have a smartphone equivalent of your desktop pages, remedy that ASAP.Until those pages are live, you should leave users on your desktop page as opposed to redirecting them to your mobile homepage.
*Mobile users who request dynamically generated URLs should be taken to an equivalent mobile URL that will properly display the information they’re seeking.
*Mobile users across all devices should be served the same content.
*Avoid mistakenly linking to desktop-optimized versions of your pages from your mobile URLs.

6.Mobile-Only 404s
Users on the desktop and mobile versions of your site should be able to access the same content.You need to remedy any instance in which mobile users receive a 404 error while trying to access a page that desktop users can see.In general, you should eliminate all 404 and soft 404 pages as quickly as possible — these could help improve your SERP positions for your site.Website auditing software will help you easily find and fix broken links and 404 pages.

7.No Rich Snippets
If you aren’t yet using Schema or Structured Data markup to categorize your content, then you’re missing out a key driver of organic CTR.Google and its users tend to respond to rich snippets that showcase examples of the information they’re seeking.

8.Not Specifying Mobile Viewport
Mobile screens come in all shapes and sizes, so if you don’t specify the correct viewports using the viewport meta tag, then your users may experience pages improperly fitted to their device.Commonmistakes include:
*Using fixed-width viewports, which are only optimized for certain devices.
*Poor minimum viewport parameters, which leave users with smaller devices high and dry.

9.Poor Mobile Design
Your design must also be mobile-friendly.So design for smartphones and tablets, not the desktop experience.Space the elements of your pages so that mobile users aren’t at risk of clicking the wrong link or button.

10.Not Cross-Checking Metrics You Rely On
Understand how the tools you use on a daily basis work, and how the metrics you rely on are calculated. When you’re optimizing — whether for mobile or desktop — make sure you use a good site auditing tool to find your gaps.Check your content, your backlinks, your title/meta tags, your schema markup, etc.everything that will play a role in your website’s success.At the same time, understand that even when different tools boast similar functions (e.g., site audit), they often deliver measurably different results.Cross-check your results against another tool’s results; you might be surprised by how much they differ.
