What is Website SEO?

SEO or search engine optimization is the improvement of technical characteristics and content of a website to meet the requirements of search engines and customer’s needs. During this process, specialists conduct an SEO website analysis to determine the areas for improvement. They analyze the position of a website among its direct Google Search competitors and build a strategy to improve its online ranking.
Websites are also optimized for particular keywords that match their domain. This helps online users to find what they are looking for much faster since search algorithms show the most relevant resources at the top. On the other hand, optimized websites get a chance to attract better-targeted traffic that is more likely to convert.
Generally, there are 3 main types of website SEO:

  • On-page SEO. This subtype of search engine optimization comprises keyword analysis, online content creation, and keyword optimization.
  • Technical SEO. This SEO type is about optimizing site speed, crawlability, website architecture, security, and responsiveness. In other words, SEO experts perform the technical website audit to find any technical bottlenecks that affect its SEO.
  • Off-site SEO. This SEO strategy is all about building backlinks and increasing the website’s authority for search engines.

To put it simply, search engine optimization is a sure way to improve the ranking positions of a website in SERP results. The better SEO a site has, the closer to the top it ranks.

Essential Role of SEO in 2020: Why Does Your Website Need an SEO Audit?

SEO is Google’s way to establish justice in Google Search. Without search engine optimization, it would be very easy to manipulate Google ranking positions. As a result, manipulators would be shown at the top of Google, whereas the websites with engaging and quality online content would rank lower.
Thus, although SEO requires additional effort from website owners, it introduces the order in Google Search. Users receive more accurate and relevant online search rankings, whereas websites have clear directions on what they should improve to rank at the top. Even though Google doesn’t share all factors taken into account by its search ranking algorithms, there are many generally approved SEO techniques. These search engine optimization strategies have proven to be effective and can help your website outperform competitors in Google.
Once you have taken steps to optimize your website or landing page for the Google Search engine, it’s necessary to check the result. To do this, you will need to conduct an SEO audit using one of the professional online SEO tools.
An online SEO checker is specialized software for an automatic audit of search engine optimization. After a quick check, such a tool will show you the main SEO issues on a website and recommend how to fix them. The regular use of SEO software is essential to keep your page at the top of Google Search and make proactive SEO changes.
In addition to that, an SEO audit with online tools has several other benefits:

  • Enhanced customer experience. Relevant online content with a convenient structure not only attracts users but makes the navigation smoother.
  • More effective marketing strategy. The analysis of popular keywords can help website owners understand what online content interests their potential customers.
  • Optimized technical characteristics of the website. After proper search engine optimization, a website will have better speed, more convenient structure, and will generally become more stable.
  • Better position in the market. SEO keyword research always requires the study of online competitors to see what keywords they use to rank in Google. Good SEO should help you win over your competitors.

Remember that SEO is the foundation of equality in Google Search. Besides, it is a free way to ensure long-lasting top search results for your website. Paid search or online ads cannot do that.

How to Check Website SEO?

Even the best free SEO tools won’t help your website rank higher online if you don’t know how to use SEO software. There are several major characteristics you need to evaluate to know the reasons behind your current SEO ranking positions.
Just open an online SEO tracker you would like to use, enter your website address, and launch the check. Make sure to:

Perform website speed audit with online speed checkers

Most top search engine ranking tools can determine whether a website is fast enough to rank high in SERPs. They either measure website speed or indicate that online speed is something you should work on. Actually, Google openly states that site speed matters for web search ranking positions and is evaluated by Google Search algorithm. Slow websites won’t rank high online. That’s why you need to start your website SEO audit with a speed checker.

Check the authority and quality of your backlinks with online SEO software

Backlinks are a key off-site SEO practice with a significant influence on website search ranking positions. External links to a website show Google algorithms that the page is credible and deserves top positions online. Hence, if you want to improve your SEO, you need to analyze the existing backlinks and build new ones. Conducting an audit of the backlinks, keep in mind that the quality of backlinks is more important than quantity. It’s preferable to focus on links with 40+ domain authority that are relevant to your industry.

Check metadata

You can either find your page in Google to see how it displays or use one of the online SEO analyzers. Some of them can run a quick check of meta descriptions, headers, titles, and other metadata. As an alternative, you can use the Yoast plugin if you manage your website content through WordPress. Although this plugin won’t run an online audit of the entire web resource, it is quite effective for basic SEO optimization of content.

Research keywords with SEO software

The fact that you conducted keyword research with a bunch of best SEO tools and online analyzers several years ago, doesn’t mean these keywords are still relevant. The trends in any industry quickly change as well as keywords and online search queries that rank best. Therefore, you need to regularly conduct small keyword research to make sure your keywords are on track. Enter the keywords in any online SEO checker that supports keyword research and see whether their popularity grows. If keywords become more popular online, you are on the right track. If not, consider selecting new keywords.
These are the main ways to analyze website SEO and ranking positions. For in-depth SEO and SERP ranking audit, you will also need to check website structure, internal URLs, old content, data markup, and online competitors. Generally, to get the overall SEO picture, free online SEO software is enough. You just need to select an SEO checker tool with the most suitable functionality.
For a full audit, SEO professionals use the combination of several best SEO analyzers and checkers. Although different online SEO tools provide distinct metrics and rely on their custom algorithms, they all evaluate website ranking potential.

Types of online tools for website SEO and SERP ranking analysis

Generally, there are 7 types of online tools for website SEO and SERP ranking analysis:

  • Speed analyzers. Online speed is essential to rank your website higher in SERPs. Fortunately, there are plenty of free speed checkers that can measure website load time. Try using Pingdom, PageSpeed Insights, WebPageTest, or any other alternative online checker. Apart from the ranking positions in SERPs, speed also affects user experience. A one-second delay in page loading decreases the number of page views by 11%. That’s why software for online speed check is a must-use to keep your website afloat.
  • Backlink building tools. Backlinks heavily impact the authority, domain rating, SEO, and SERP of a website. They show search engines that your web resource is credible and takes a noticeable place among competitors. Although there are some ways to build backlinks without link building software and specialized tools, it’s inefficient. You are likely to hear too many rejections and create low-quality backlinks with poor domain rating and authority. With simple tools, checkers, and analyzers, you can analyze the backlink profile of your competitors and available options. This will give you ideas on how to use link building for search engine optimization and which third-party resources can benefit your SEO, domain authority, and SERPs.
  • Rank tracking tools. Let’s say you have finished writing content according to all search engine optimization rules. What’s next? After the content is published, you need to make sure the articles and keywords properly rank on Google. To perform such analysis manually, you would need to type each keyword in Google, trying to find your pages in SERPs. Don’t do that! There is a range of rank trackers that determine the exact position of a keyword in Google ranking. They show how the SERP position changed compared to the previous period and often provide the same information on competitors’ websites. Some rank analyzers also allow you to download weekly/monthly reports and send email notifications.
  • Keyword Research tools. No need to say that keyword research is the foundation of website search engine optimization. Advanced keyword analysis software significantly speeds up the discovery phase and brings numerous other SEO benefits. In particular, keyword analyzers can show the content gaps of your competitors. This allows you to easily rank for keywords that others rarely target in their content. Besides, keyword ranking software helps to constantly keep track of trending keywords and instantly create content targeting them. It’s another way to outperform your competitors and make your website rank higher in SERP positions.
  • SEO reporting tools. SEO reporting software is necessary for anyone who wants to rank in the top SERPs and stay there forever. The thing is that search engine optimization is a continuous process that requires monitoring and tuning-up. Such website checkers analyze website performance based on selected KPIs and regularly provide SEO reports. Besides, SEO reporting tools send the results of experiments and other valuable information. Thanks to this, you always know the state of search engine optimization and can remain flexible in your SEO strategy. The current SEO software market offers hundreds of tools with reporting functionality. You may use SEMrush, Google Data Studio, or Plerdy that supports a website SEO checker called SEO Alerts.
  • Competitor analysis tools. If you want to launch a successful SEO strategy, treat competitors like your teachers, not like your enemies. Competitor websites have been in your industry for a while and introduced diverse SEO ranking techniques. Use competitor SEO tracking software to learn what works for your competitors and what doesn’t. With such SEO checkers, you can view the traffic, ranking positions, SERPs, backlinks, and other metrics of your competitors. A clear picture of your market segment will help you find your SEO path and use the most effective search engine optimization techniques.
  • Local SEO tools. Although Google ranking is global, many buying decisions happen locally. Customers who need car rental services in Paris would rather search for “car rental services in Paris” than for “car rental.” Thus, in case your business is tied to a specific location, remember to use local SEO software for website optimization. Such SEO optimization tools usually comprise: an automated listings finder (to look for directory listing opportunities), functionality for automated update of all listings, review management features. You can either choose a local SEO checker that focuses on one of the listed features or pick an all-in-one website optimization tool that includes listings as one of its capabilities.

The majority of advanced online SEO checkers combine several types of the described tools. You can find SEO optimization software that evaluates your SERP rating and provides SEO analysis reporting at the same time.
