Detect your mistakes

The quick way to start your technical SEO checklist is to spot your mistakes. Thus, you have a roadmap to correct your mistakes. Technical errors result in crawlers not indexing your pages properly. In the worst-case scenario, the browser won’t index your page. Fixing these errors is a necessary first step in any technical SEO checklist.

Website Architecture

That shows how information is structured on a website. Let’s explain this with an example. For this, let’s consider organizing web pages into categories. We may also consider the ways used to navigate between sections of the website. Website architecture affects how users experience your website. It also affects how search engines experience your website.

Let’s examine the features of websites that have bad architecture. These websites may have many dead-end pages. Besides, these websites may also have subdomains or subdirectories that are unwieldy. On the other hand, a website with good architecture does not use the browsing time unnecessarily. Search engines rank these websites faster on results pages. Let’s see what you can do to make your website have a good architecture.

First, make sure your website has an XML sitemap. Then, organize your website URLs in a logical flow. You can do this as follows. Organize your website URLs from domain to category to subcategory. This way, the new URLs that will come will fit this architecture. In the end, optimize your website URL structures for search. To do this, move the main keywords closer to the root domain. Also, do not keep the URL length longer than 60 characters.

Duplicate Content

These content are content that appears on multiple pages or domains in the same domain. Duplicate content issues are also important for technical SEO checklist. These contents are not malicious. That’s why they don’t get penalties from Google. However, you still need to fix such content. There are several main reasons for this. Browsers need to know which version of a web page is the original or canonical page. Otherwise, they will not know which result to show in the search results. So, your webpages will not be in the rankings it deserves on the results pages. Also, your webpages may be in a lower order than the value for which it was filtered.

Schema Markup

This has no direct effect on search results. It is also called Structured Data or Micro Data. It helps determine the content of the page. Users search on Google for some specific purposes. Schema markup enables search engines to serve users and website owners better. When you start using microdata, search engines will get to know your site better. This way, it may understand the content of your website better. Then, it provides more relevant search results to users. Schema markup allows your website to get much more engagement. So, you may get better rankings on Google or other search engines.

website speed

Website Speed

Let’s share the result of online research on this subject. If it takes more than three seconds to load a webpage, almost half of the users leave the website. Something happens when these users leave your website in this way. This behavior sent negative signals to search engines about the quality of your website. Google confirmed this in 2010. The speed of your website is an important signal that affects the ranking factor. There are several improvements you can make to increase the speed of your website. These are as follows:

  • Minimize HTML, JavaScript, and CSS files. Combining them may also be helpful.
  • Eliminate unnecessary code such as line breaks.
  • Tools like HandBrake and TinyPNG quickly compress large files. By using these tools, you may present your images in highly compressed formats.
  • Reduce plugins, scripts, and redirect chains. The low number of codes and files on your website makes it open faster. You should keep the weight of your website and page requests to a minimum.

Servers used to run on Hypertext Transfer Protocol. This method was a fast way to send system data. However, it was not safe. So, it is better to use HTTPS, this method’s additional protocol. This protocol encrypts data and transports it securely on the web. In doing so, it uses the secure socket layer. Google announced that it recognized HTTPS as a ranking factor in 2014. This method is a good way to protect users’ data.

Htaccess 301 Redirect

That is a control file that allows Apache server configuration changes. This file is located in the root directory of your website. If you don’t have this file, you may create it yourself. For a 301 redirect, you first need to locate the htaccess file. To do this, follow the steps below.

  • Login to your FTP.
  • Go to the root directory.
  • Organize your file with software like notepad. If this file does not exist in the root directory, create it.
  • Add your 301 redirect commands to redirect a particular old page to the new page.
  • You need to add another blank line at the end of the file. There is a reason for this. Your server reads this file line by line. For this reason, you must add a last blank line to the file to indicate that you have finished.

That’s all you have to do.


Crawling is the process of search engine spiders browsing the pages of your website within certain time intervals. Search engine bots do this by following the links your pages give to each other within your website. It performs this process by following the links given to your web pages outside of your website. These bots are not able to spend time exploring every single page on the internet.

At this point, we may assume that they are progressing on the quality value they give to each website. This value that these bots assign to your website is called the crawl budget in the SEO world. The crawl budget has no specific numerical value. Thanks to this technical SEO checklist, you may use this budget efficiently. So, you may enable spiders to discover, crawl and index your web pages more frequently.

Using the Browser Caching Feature

This feature is a feature that increases the opening speed of your website. This way, browsers do not have to load images and other resources on the site over and over again. When users enter the website after their first visit, browsers pull these resources from the cache for a specified period. Thus, users view the site much faster. The same is true for bots. When bots enter a webpage, recalling static resources each time that will not easily change causes extra waiting time on their behalf.

These static resources can be resources such as logos and favicon. You should offer bots that try to crawl your web pages to load all of your page content as quickly as possible. You may achieve this by activating the cache feature. For this, you must set an expiration date or a maximum lifetime in HTTP headers for static resources. These settings tell the browser to load those already downloaded on the local disk, not resources on the network.

Spiders associate your web pages with the keywords on your website. Then, they add them to their index. This process is called indexing. It is one of the first terms that come to mind when it comes to technical SEO checklist. We can explain the realization of the indexing process as follows. A user performs a search query on the search engine. The search engine does not perform the indexing process live during this time. First, it searches for page groups that were previously associated with the relevant search query and indexed. Then, it sorts the results related to the search query among them. Spiders consider many algorithmic factors when ranking these page groups.

They also consider a large number of ranking signals. This process is called ranking. The top 10 results that the search engine ranks as organic results on the first page are the most important results. Therefore, all your web pages should be crawlable and indexable.

Link Building

These links are of two types, Off-site and On-Site. Off-site link building refers to off-site links. On-site link building represents links within the website. Link building is the process of getting links from other websites to your website. A hyperlink is a way users navigate pages on the internet. Search engines use links to crawl web pages. Search engine bots scan the pages on your website one by one and follow the links in them. There are many different techniques for link building. However, the connections created for today’s algorithms are of critical importance. The wrong actions you take may cause negative results for your website. There are a few techniques you can do to gain backlinks. Let’s talk about them now.

Create fun, high-quality, original, or unusual content on your website that people want to share. Before creating your content, determine who your target audience is. Once you create valuable content and know where your audience is, it will be easier to earn links. If your content is related to your users, they may link to your website. This technique is called internal links in technical SEO checklist. This technique redirects both Google bot and users by creating a hyperlink between pages.

HTTP Response Codes

That is the server’s response to a request made by the browser. So, these are called HTTP response codes or status codes. These codes are one of the most obvious ways to see what is happening between the browser and the server. Search engine spiders read these codes to see the status of the relevant page. This happens when a browser makes the first request to the server to load a website. There are a few important codes among these codes in terms of technical SEO. These are 2xx, 3xx, 4xx, and 5xx response codes.

Mobile-First Indexing

Before this practice, desktop pages determined both mobile and desktop search results. The rates of determining factors such as mobile click-through rates and mobile site speed were lower. These data caused the same page to rank in desktop and mobile results with a difference of several positions. In 2018, Google made an announcement. In this announcement, Google announced that they had switched to mobile priority indexing. Thus, the content offered by the mobile pages began to determine the position of the desktop pages. In this regard, Google states that it will always have a single indexing method. In other words, there will not be an index separate from the main directory.

Today, Google indexed desktop pages more. However, over time, these pages will be replaced by mobile versions. Google Search Console will soon send messages to website owners whether they have switched to mobile-priority indexing. Most websites have received this transition message.

In Google Search Console, you may see that the crawl rates made from Smartphone Googlebot increase over time. With mobile priority indexing, the mobile version of the relevant page will appear in the search results. For this reason, you should be ready in order not to lose traffic and position with the arrival of the update. So, it is of great importance to be ready for Mobile Priority Indexing. Based on this data, we may understand that page contents are the basis of mobile-first indexing. Therefore, you should make sure that all the content you offer in the desktop version is also available on mobile pages. The scope of these contents is as follows:

  • Images
  • Category Descriptions
  • CSS and JS Resources
  • Structured Data Markings
  • Breadcrumb
  • In-Site Link Setup
  • All data types presented on the webpage

You need to make sure that you are presenting the content in the full version. You may use the mobile compatibility test for this.
