They overlap a little on speed and search access and otherwise answer different questions. ### Fix overlaps once Where both flag the same issue, such as a slow page, fix it once. PostCliq’s weekly history shows whether it stayed fixed. [How PostCliq checks a site](https://postcliq.com/methodology) ## What PostCliq does not do. Knowing the limits is part of choosing well. - It is not a full technical SEO crawler. Search visibility is one of seven categories. - It is not a keyword, backlink or rank-tracking tool. Its Google picture is an estimate for your own site. - It is free with clear weekly limits, not unlimited: one website for a brand, five client sites for an agency, one audit per site each rolling seven days. - It does not fix your website, guarantee results or certify security. WP Creative can make changes, as a separate and optional service. ## Questions people ask. Is Semrush Site Audit free? Partly. A free Semrush account can audit 100 pages per audit and 100 pages per month. Paid plans start at USD 139 a month on monthly billing, with lower prices on annual billing, and crawl far more pages. Is PostCliq an SEO audit? Partly. Search visibility is one of its seven categories, but PostCliq ranks everything by the effect on enquiries, with the enquiry journey weighted most. For deep technical SEO, a dedicated crawler goes further. Which is better for a small B2B website? If the site’s job is enquiries and you have no SEO specialist, PostCliq gives you a shorter, ranked list with evidence. If organic search growth is the main goal, a dedicated SEO audit such as Semrush goes deeper. Can I use both? Yes. They overlap a little on speed and search access and otherwise answer different questions. Use Semrush for SEO health and PostCliq for the enquiry path, and fix anything both flag once. How many pages does PostCliq check? Up to 50 public pages per audit, with up to five rendered in a real browser, once per site each rolling seven days.
