Posted May 18th, 2020 in SEO/SEM. Tagged: , , .

Most business owners nowadays are not even aware if their website is reaching the potential customers or not. And believe us when we say this, not having an effective outreach is the same as not having a website. In today’s constantly evolving internet spectrum, if you own a website and intend to drive business through it, Search Engine Optimization (SEO) is imperative for you. SEO just works on the simple fact that for someone to see your content and website it, must first appear in relevant searches.

But SEO is not that simple, it involves keywords, backlinks, content marketing and user experience and more elements. Yes, a lot of domain knowledge is needed to excel in SEO. But all is not lost if you can’t afford a team to handle SEO for your website. There are ways to make things simpler and this is where SEO crawler tools come in.

What is an SEO Crawler and how does it work?

When it comes to search engines like Google, Bing, and Yahoo, there are bots to scout for content when someone conducts an internet search. The process is called crawling and involves following links for the page to find and read content. The next step is indexing, which includes on-boarding the content encountered to search engine servers and finally ranking the results on the basis of relevance.

SEO crawlers work the same way as search engine crawlers, except for the fact that indexing and ranking steps are skipped in the process. Instead, they utilize the data of the initial step to provide useful insights. Think of SEO crawlers as tools to view your website from the search engine’s point of view. A great SEO crawler tool helps you analyze your website for technical SEO and content and reports common issues like:

Duplicate Content

There are several ways that duplicate content can end up on your website. The reason can be as simple as:

  • Selected theme or template causing duplicity in title and descriptions
  • Multiple products having the same content with difference in key information like color and size, a common issue with ecommerce websites
  • Paginated lists
  • Blogs that feature product listings with the same content

Conceptually, removing duplicate content is not that hard to fix. You can easily proofread the website to encounter and fix such accidental mistakes. But what if you are dealing with tons of products and listings? Going through each doesn’t make sense and is not practical. A good SEO crawler can help you fix this by adding canonical tags whenever there is duplicate content encountered.

Improper Indexing

SEO crawler tools help you improve the index-ability of your website and believe us, a lot depends on how a search engine indexes the relevant pages of your website. Alternatively, you can use robots.txt file and the meta-robots tag to tackle issues with the indexing of your website, but if not handled responsibly, people may end up seeing irrelevant content.

An SEO crawler handles such issues expertly. It analyzes your website and provides you a list of pages that are disallowed with no index tags. And following this, you can make sure that you have all the right pages indexed for search engine results.

Poor Redirects

Redirects are a necessary evil when it comes to migrating pages or whole websites. A whole lot can go wrong when implementing these and you may end up with broken redirects that lead to nowhere, redirect chains that lead to slow download time, and redirect loops that cause users to move back and forth between pages that never load. All of these can end up hampering the user trust towards your website. SEO crawlers let you test all your redirects for any such issues.

Insecure Pages

Security is a critical aspect most search engines consider while raking content, especially if your website explores financial and personal information. You may have insecure pages on your website, a common problem encountered when you don’t entirely migrate from HTTP to HTTPS.

This will not only hamper your ranking on the search engine but also you may lose the trust of your valuable existing user base. Who would want to go back to a website that shows security warning while loading? SEO crawler helps you improve when dealing with such mixed content.
