Dear colleagues! I present to you the SiteAnalyzer program, which is intended for technical analysis and site audit (server response codes, presence of "broken" links, links to external resources, check for availability of title, keywords, description, h1-h6 headers, check for duplicate pages, calculate PageRank, etc). This is a free analogue of the program Screaming Frog SEO Spider and similar. The analysis is performed by scanning all pages of the site (crawling the site by links), after which, based on parsed data, you can audit the parameters of interest. Screens Key features Scanning of all pages of the site, as well as images, scripts and documents Getting server response codes for each page of the site (200, 301, 302, 404, 500, 503, etc.) Determining the presence and content of Title, Keywords, Description, H1-H6 Find and display "duplicate" pages, meta tags and headers Determining the presence of the attribute rel="canonical" for each page of the site Following the directives of the file "robots.txt", the meta tag "robots", or X-Robots-Tag Accounting "noindex" and "nofollow" when crawling the pages of the site Reference analysis: the definition of internal and external links for any page of the site Calculation of internal PageRank for each page of the site Determining the number of redirects from the page Sitemap "sitemap.xml" generation (with the possibility of splitting into several files) Filtering data by any parameter (flexible configuration of filters of any complexity) Export reports to CSV and Excel (full report in Excel format) Differences from analogues Low demands on computer resources, low consumption of RAM To store data, a local database is used that is characterized by its performance and reliability Scanning websites of any volumes due to the low requirements of computer resources Portable format (works without installation on a PC or directly from removable media) I will be glad to any comments and wishes on the work and development of the program.
