1- Check Indexing of Your Pages
For maximum benefits, you should get all of your website pages indexed. But sometimes, Google removes web pages from Google index. You should keep checking indexing of your web pages.
2- Check Crawlability
Site structure, internal link structure, looped redirects, unsupported scripts sometimes affect crawlability. So you should keep checking crawlability from time to time.
3- Improve Page Speed
As mentioned earlier, mobile searches are more than desktop searches now. And Google is experimenting mobile first indexing and will start considering page speed as a ranking factor by July 2018. You should improve page speed of your website.
4- Don’t Forget to Use Canonical Links
If used properly, canonical links can solve the duplicate content issue. Yoast has published a long guide on the topic.
5- Use Proper Redirects
Redirects are used to send search engines and users to different URLs from the ones they requested. When you are redirecting one URL to another, you should follow the best redirect practices to retain SEO value.
6- Use Structured Data
Search engines work hard to decipher the content of a page. By using structured data, you will provide search engine explicit clues about the meaning of the content.
7- Don’t Use Flash On Your Website
As all search engines are not able to crawl and index flash (and the ones that do often do it with error), you should avoid using flash on your website.
8- Accelerated Mobile Pages Can Improve Ranking
Though Google has repeatedly said that accelerate mobile pages are not a ranking factor, we can understand that having AMPs can improve ranking. How? AMPs improve page speed. And Google will start considering page speed as a mobile ranking factor.
9- Optimize for Voice Search
With the exponential growth of mobile searches, the trend of voice search is catching up very fast. You should make sure that your website is optimized for voice search. I have written a detailed guide to optimizing for Google voice search.
10- Remove Site’s Downtime
You should make sure that your site has minimum downtime because lots of downtime from server issues may affect your ranking. If you don’t fix it, your site might be deindexed.
11- Use Geo-Targeting
You should consider Geo-targeting if you want to promote your business in a specific country. Google might give a little preference to websites that have local server IP and country-specific name.
12- Remove All Technical Errors
Coming to the end of SEO checklist for technical SEO, your website should be free from every technical error. Even a small technical error can have a serious implication. Off page SEO are techniques that are executed outside the website to improve the search visibility of a website. You must understand that offsite SEO is not just about building links. Off page activities go deeper than that.
13- Earn Backlinks from Aged Domains
Needless to say, backlinks from aged domains have more value than backlinks from newer domains. So keep trying to acquire backlinks from aged domains.
14- Earn Backlinks from Different Root Domains
One of the most important ranking factors is to get backlinks from different root domains. According to a Moz study, “The number of linking root domains correlates well with rankings.”
15- .edu and .gov Links
As Google values high-authority links, many SEO experts believe that .edu and .gov links have a special place in Google algorithm. And there is a valid reason behind it.
Till we meet again. Stay awesome 😉.
